Life and career
Childhood and first marriage (1926–1944)
Monroe was born Norma Jeane Mortenson at the
Los Angeles County Hospital on June 1, 1926, as the third child of Gladys Pearl Baker (née Monroe, 1902–1984). Gladys, the daughter of two poor
Midwestern migrants to California, was a
flapper and worked as a film negative cutter at
Consolidated Film Industries. When she was fifteen, Gladys married a man nine years her senior, John Newton Baker, and had two children by him, Robert (1917–1933) and Berniece (born 1919). She filed for divorce in 1921, and Baker took the children with him to his native Kentucky. Monroe was not told that she had a sister until she was twelve, and met her for the first time as an adult. In 1924, Gladys married her second husband—Martin Edward Mortensen—but they separated before she became pregnant with Monroe by a different man; they divorced in 1928.
 The identity of Monroe's father is unknown and Baker was most often used as her surname.
Monroe's early childhood was stable and happy. While Gladys was mentally and financially unprepared for a child, she was able to place Monroe with foster parents Albert and Ida Bolender in the rural town of
Hawthorne soon after the birth. They raised their foster children according to the principles of
evangelical Christianity. At first, Gladys lived with the Bolenders and commuted to work in Los Angeles, until longer work shifts forced her to move back to the city in early 1927. She then began visiting her daughter on weekends, often taking her to the cinema and to sightsee in Los Angeles. Although the Bolenders wanted to adopt Monroe, by the summer of 1933, Gladys felt stable enough for Monroe to move in with her and bought a small house in
Hollywood. They shared it with lodgers, actors George and Maude Atkinson and their daughter, Nellie. Some months later, in January 1934, Gladys had a mental breakdown and was diagnosed with
paranoid schizophrenia. After several months in a rest home, she was committed to the
Metropolitan State Hospital. She spent the rest of her life in and out of hospitals, and was rarely in contact with Monroe.
—Monroe in an interview for
Life in 1962
"When I was five I think, that's when I started wanting to be an actress. I loved to play. I didn't like the world around me because it was kind of grim, but I loved to play house. It was like you could make your own boundaries... When I heard that this was acting, I said that's what I want to be... Some of my foster families used to send me to the movies to get me out of the house and there I'd sit all day and way into the night. Up in front, there with the screen so big, a little kid all alone, and I loved it."
Monroe became a
ward of the state, and her mother's friend, Grace McKee Goddard, took responsibility over her and her mother's affairs. In the following four years, she lived with several foster families, and often switched schools. For the first sixteen months, she continued living with the Atkinsons; she was sexually abused during this time.
[b] Always a shy girl, she now also developed a
stutter and became withdrawn. In the summer of 1935, she briefly stayed with Grace and her husband Erwin "Doc" Goddard and two other families, until Grace placed her in the Los Angeles Orphans Home in Hollywood in September 1935. While the orphanage was "a model institution", and was described in positive terms by her peers, Monroe found being placed there traumatizing, as to her "it seemed that no one wanted me".
Monroe and first husband James Dougherty, c.1943–1944
Encouraged by the orphanage staff who thought that Monroe would be happier living in a family, Grace became her
legal guardian in 1936, although she was not able to take her out of the orphanage until the summer of 1937. Monroe's second stay with the Goddards lasted only a few months, as Doc molested her. After staying with various of her and Grace's relatives and friends in Los Angeles and
Compton, Monroe found a more permanent home in September 1938, when she began living with Grace's aunt, Ana Atchinson Lower, in the
Sawtelle district. She was enrolled in
Emerson Junior High School and was taken to weekly
Christian Science services with Lower. While otherwise a mediocre student, Monroe excelled in writing and contributed to the school's newspaper. Due to the elderly Lower's health issues, Monroe returned to live with the Goddards in
Van Nuys in either late 1940 or early 1941. After graduating from Emerson, she began attending
Van Nuys High School.
In early 1942, the company that Doc Goddard worked for required him to relocate to
West Virginia. California laws prevented the Goddards from taking Monroe out of state, and she faced the possibility of having to return to the orphanage. As a solution, she married their neighbors' son, 21-year-old factory worker James "Jim" Dougherty, on June 19, 1942, just after her 16th birthday. Monroe subsequently dropped out of high school and became a housewife; she later stated that the "marriage didn't make me sad, but it didn't make me happy, either. My husband and I hardly spoke to each other. This wasn't because we were angry. We had nothing to say. I was dying of boredom." In 1943, Dougherty enlisted in the
Merchant Marine. He was initially stationed on
Catalina Island, where she lived with him until he was shipped out to the
Pacific in April 1944; he would remain there for most of the next two years. After Dougherty's deployment, Monroe moved in with his parents and began working at the
Radioplane Munitions Factory to participate in the war effort and to earn her own income.
Modeling and first film roles (1945–1949)
Monroe photographed by Conover while working at the Radioplane factory in late 1944
In late 1944, Monroe met photographer
David Conover, who had been sent by the
U.S. Army Air Forces'
First Motion Picture Unit (FMPU) to the factory to shoot morale-boosting pictures of female workers. Although none of her pictures were used by the FMPU, she quit working at the factory in January 1945 and began modeling for Conover and his friends.
 She moved out of her in-laws' home, defying them and her husband, and signed a contract with the Blue Book Model Agency in August 1945. She began to occasionally use the name Jean Norman when working, and had her curly brunette hair straightened and dyed blonde to make her more employable. As her figure was deemed more suitable for
pin-up than fashion modeling, she was featured mostly in advertisements and men's magazines. According to the agency's owner, Emmeline Snively, Monroe was one of its most ambitious and hard-working models; by early 1946, she had appeared on 33 magazine covers for publications such as
Pageant, U.S. Camera, Laff, and Peek.
Impressed by her success, Snively arranged a contract for Monroe with an acting agency in June 1946. After an unsuccessful interview with producers at
Paramount Pictures, she was given a screentest by
Ben Lyon, a
20th Century-Fox executive. Head executive
Darryl F. Zanuck was unenthusiastic about it, but he was persuaded to give her a standard six-month contract to avoid her being signed by rival studio
[c] Monroe's contract began in August 1946, and she and Lyon selected the
stage name "Marilyn Monroe". The first name was picked by Lyon, who was reminded of Broadway star
Marilyn Miller; the last was picked by Monroe after her mother's maiden name. In September 1946, she divorced Dougherty, who was against her having a career.
Monroe during her modeling career
Monroe had no film roles during the first months of her contract and instead dedicated her days to acting, singing and dancing classes. Eager to learn more about the film industry and to promote herself, she also spent time at the studio lot to observe others working. Her contract was renewed in February 1947, and she was soon given her first two film roles: nine lines of dialogue as a waitress in the drama
Dangerous Years (1947) and a one-line appearance in the comedy
Scudda Hoo! Scudda Hay! (1948).
[d] The studio also enrolled her in the
Actors' Laboratory Theatre, an acting school teaching the techniques of the
Group Theatre; she later stated that it was "my first taste of what real acting in a real drama could be, and I was hooked". Monroe's contract was not renewed in August 1947, and she returned to modeling while also doing occasional odd jobs at the studio.
Determined to make it as an actress, Monroe continued studying at the Actors' Lab, and in October she appeared as a blonde
vamp in the short-lived play Glamour Preferred at the
Bliss-Hayden Theater, but the production was not reviewed by any major publication. To promote herself, she frequented producers' offices, befriended gossip columnist
Sidney Skolsky, and entertained influential male guests at studio functions, a practice she had begun at Fox. She also became a friend and occasional sex partner of Fox executive
Joseph M. Schenck, who persuaded his friend
Harry Cohn, the head executive of Columbia Pictures, to sign her in March 1948.

in 1947. She appeared in two small film roles during the contract and was let go after a year.
While at Fox, her roles had been that of a "girl next door"; at Columbia, she was modeled after
Rita Hayworth. Monroe's hairline was raised by electrolysis and her hair was bleached even lighter, to platinum blond. She also began working with the studio's head drama coach,
Natasha Lytess, who would remain her mentor until 1955. Her only film at the studio was the low-budget musical
Ladies of the Chorus (1948), in which she had her first starring role as a chorus girl who is courted by a wealthy man. During the production, she began an affair with her vocal coach, Fred Karger, who paid to have her slight overbite corrected. Despite the starring role and a subsequent screen test for the lead role in
Born Yesterday (1950), Monroe's contract was not renewed. Ladies of the Chorus was released in October and was not a success.
After leaving Columbia in September 1948, Monroe became a protégée of
Johnny Hyde, who was the vice president of the
William Morris Agency. Hyde represented her and their relationship soon became sexual, although she refused his proposals of marriage. To advance Monroe's career, he paid for a silicone prosthesis to be implanted in her jaw and possibly for a
rhinoplasty, and arranged a bit part in the
Marx Brothers film
Love Happy (1950). Monroe also continued modeling, and in May 1949 she posed nude for photos taken by
Tom Kelley. Although her role in Love Happy was very small, she was chosen to participate in the film's promotional tour in New York that year.
Monroe appeared in six films that were released in 1950. She had bit parts in Love Happy,
A Ticket to Tomahawk,
Right Cross and
The Fireball, but also made minor appearances in two critically acclaimed films:
The Asphalt Jungle and
Joseph Mankiewicz's drama
All About Eve. In the former, Monroe played Angela, the young mistress of an aging criminal. Although only on the screen for five minutes, she gained a mention in
Photoplay and according to Spoto "moved effectively from movie model to serious actress". In All About Eve, Monroe played Miss Caswell, a naïve young actress.
Following Monroe's success in these roles, Hyde negotiated a seven-year contract with 20th Century-Fox in December 1950. He died of a heart attack only days later, which left her devastated. Despite her grief, 1951 became the year in which she gained more visibility. In March, she was a presenter at the
23rd Academy Awards, and in September,
Collier's became the first national magazine to publish a full-length profile of her. She had supporting roles in four low-budget films: in the
Home Town Story, and in three moderately successful comedies for Fox,
As Young as You Feel,
Love Nest, and
Let's Make It Legal. According to Spoto all four films featured her "essentially [as] a sexy ornament", but she received some praise from critics:
Bosley Crowther of
The New York Times described her as "superb" in As Young As You Feel and Ezra Goodman of the
Los Angeles Daily News called her "one of the brightest up-and-coming [actresses]" for Love Nest. To further develop her acting skills, Monroe began taking classes with
Michael Chekhov and mime
Lotte Goslar. Her popularity with audiences was also growing: she received several thousand letters of fan mail a week, and was declared "Miss
Cheesecake of 1951" by the army newspaper
Stars and Stripes, reflecting the preferences of soldiers in the
Korean War. In her private life, Monroe was in a relationship with director
Elia Kazan, and also briefly dated several other men, including director
Nicholas Ray and actors
Yul Brynner and
Monroe became a
top-billed actress in the second year of the Fox contract. Gossip columnist
Florabel Muir named her the "
it girl" of 1952 and
Hedda Hopper described her as the "cheesecake queen" turned "box office smash".
 In February, she was named the "best young box office personality" by the
Foreign Press Association of Hollywood,
 and began a highly publicized romance with retired
New York Yankee
Joe DiMaggio, who was one of the most famous sports personalities of the era. The following month, a scandal broke when she revealed in an interview that during 1949 she had posed for nude pictures, which were featured in calendars. Fox had learned of the photographs some weeks earlier, and to contain the potentially disastrous effects on her career, the studio and Monroe had decided to talk about them openly while stressing that she had only posed for the photos while she was in a dire financial situation. The strategy succeeded in getting her public sympathy and increased interest in her films: the following month, she was featured on the cover of Life as "The Talk of Hollywood". Monroe added to her reputation as a new sex symbol with other publicity stunts that year, such as wearing a revealing dress when acting as Grand Marshal at the
Miss America Pageant parade, and by stating to gossip columnist
Earl Wilson that she usually wore no underwear.
Clash by Night
(1952). The film allowed Monroe to display more of her acting range in a dramatic role.
Regardless of the popularity of her sex appeal, Monroe wished to present more of her acting range, and in the summer of 1952 she appeared in two commercially successful dramas. The first was
Clash by Night, for which she was loaned to RKO and played a fish cannery worker; to prepare, she spent time in a real fish cannery in
Monterey. She received positive reviews for her performance:
The Hollywood Reporter stated that "she deserves starring status with her excellent interpretation", and Variety wrote that she "has an ease of delivery which makes her a cinch for popularity".
 The second film was the thriller
Don't Bother to Knock, in which she starred as a mentally disturbed babysitter and which Zanuck had assigned for her to test her abilities in a heavier dramatic role. It received mixed reviews from critics, with Crowther deeming her too inexperienced for the difficult role,
Variety blaming the script for the film's problems.
Monroe's three other films in 1952 continued typecasting her in comic roles that focused on her sex appeal. In
We're Not Married!, her starring role as a beauty pageant contestant was created solely to "present Marilyn in two bathing suits", according to its writer
Nunnally Johnson. In
Monkey Business, in which she was featured opposite
Cary Grant, she played a secretary who is a "dumb, childish blonde, innocently unaware of the havoc her sexiness causes around her". In
O. Henry's Full House, her final film of the year, she had a minor role as a prostitute.
During this period, Monroe gained a reputation for being difficult on film sets; the difficulties worsened as her career progressed. She was often late or did not show up at all, did not remember her lines, and would demand several re-takes before she was satisfied with her performance. Monroe's dependence on her acting coaches—first Natasha Lytess and later
Paula Strasberg—also irritated directors. Monroe's problems have been attributed to a combination of perfectionism, low self-esteem, and
stage fright; she disliked the lack of control she had on her work on film sets, and never experienced similar problems during photo shoots, in which she had more say over her performance and could be more spontaneous instead of following a script.
 To alleviate her anxiety and chronic
insomnia, she began to use
amphetamines and alcohol, which also exacerbated her problems, although she did not become severely addicted until 1956. According to
Sarah Churchwell, some of Monroe's behavior especially later in her career was also in response to the condescension and sexism of her male co-stars and directors. Similarly, Lois Banner has stated that she was bullied by many of her directors.
Rising star (1953)
Monroe starred in three movies that were released in 1953 and emerged as a major sex symbol and one of Hollywood's most bankable performers.
 The first of these was the
Niagara, in which she played a femme fatale scheming to murder her husband, played by
Joseph Cotten. By then, Monroe and her make-up artist
Allan "Whitey" Snyder had developed the make-up look that became associated with her: dark arched brows, pale skin, "glistening" red lips and a beauty mark. According to Sarah Churchwell, Niagara was one of the most overtly sexual films of Monroe's career, and it included scenes in which her body was covered only by a sheet or a towel, considered shocking by contemporary audiences. Its most famous scene is a 30-second
long shot of Monroe shown walking from behind with her hips swaying, which was heavily used in the film's marketing.
When Niagara was released in January,
women's clubs protested that the film was immoral, but the movie proved popular with audiences and grossed $6 million at the box office. While Variety deemed it "clichéd" and "morbid", The New York Times commented that "the falls and Miss Monroe are something to see", as although Monroe may not be "the perfect actress at this point ... she can be seductive – even when she walks".
 Monroe continued to attract attention with her revealing outfits in publicity events, most famously at the Photoplay awards in January 1953, where she won the "Fastest Rising Star" award. She wore a skin-tight gold
lamé dress, which prompted veteran star
Joan Crawford to describe her behavior as "unbecoming an actress and a lady" to the press.
While Niagara made Monroe a sex symbol and established her "look", her second film of the year, the satirical musical comedy
Gentlemen Prefer Blondes, established her screen persona as a "dumb blonde". Based on
bestselling novel and
its Broadway version, the film focuses on two "gold-digging"
showgirls, Lorelei Lee and Dorothy Shaw, played by Monroe and
Jane Russell. The role of Lorelei was originally intended for
Betty Grable, who had been 20th Century-Fox's most popular "
blonde bombshell" in the 1940s; Monroe was fast eclipsing her as a star who could appeal to both male and female audiences. As part of the film's publicity campaign, she and Russell pressed their hand and footprints in wet concrete outside
Grauman's Chinese Theatre in June. Gentlemen Prefer Blondes was released shortly after and became one of the biggest box office successes of the year by grossing $5.3 million, more than double its production costs. Crowther of The New York Times and William Brogdon of Variety both commented favorably on Monroe, especially noting her performance of "
Diamonds Are a Girl's Best Friend"; according to the latter, she demonstrated the "ability to sex a song as well as point up the eye values of a scene by her presence".
In September, Monroe made her television debut in the
Jack Benny Show, playing Jack's fantasy woman in the episode "Honolulu Trip". She co-starred with Betty Grable and
Lauren Bacall in her third movie of the year,
How to Marry a Millionaire, which was released in November. It featured Monroe in the role of a naïve model who teams up with her friends to find rich husbands, repeating the successful formula of Gentlemen Prefer Blondes. It was the second film ever released in
CinemaScope, a widescreen format that Fox hoped would draw audiences back to theaters as television was beginning to cause losses to film studios. Despite mixed reviews, the film was Monroe's biggest box office success at that point in her career, earning $8 million in world rentals.
Monroe was listed in the annual
Top Ten Money Making Stars Poll in both 1953 and 1954,
 and according to Fox historian Aubrey Solomon became the studio's "greatest asset" alongside CinemaScope. Monroe's position as a leading sex symbol was confirmed in December 1953, when
Hugh Hefner featured her on the cover and as centerfold in the first issue of
Playboy. The cover image was a photograph taken of her at the Miss America Pageant parade in 1952, and the centerfold featured one of her 1949 nude photographs.
Conflicts with 20th Century-Fox and marriage to Joe DiMaggio (1954–1955)
Posing for soldiers in Korea after a
performance in February 1954, during her suspension by the studio
Although Monroe had become one of 20th Century-Fox's biggest stars, her contract had not changed since 1950, meaning that she was paid far less than other stars of her stature and could not choose her projects or co-workers. She was also tired of being typecast, and her attempts to appear in films other than comedies or musicals had been thwarted by Zanuck, who had a strong personal dislike of her and did not think she would earn the studio as much revenue in dramas. When she refused to begin shooting yet another musical comedy, a film version of
The Girl in Pink Tights, which was to co-star
Frank Sinatra, the studio suspended her on January 4, 1954.
The suspension was front page news and Monroe immediately began a publicity campaign to counter any negative press and to strengthen her position in the conflict. On January 14, she and Joe DiMaggio, whose relationship had been subject to constant media attention since 1952, were married at
San Francisco City Hall. They then traveled to Japan, combining a honeymoon with his business trip. From there, she traveled alone to Korea, where she performed songs from her films as part of a
USO show for over 60,000 U.S. Marines over a four-day period. After returning to Hollywood in February, she was awarded Photoplay's "Most Popular Female Star" prize. She reached a settlement with the studio in March: it included a new contract to be made later in the year, and a starring role in the film version of the Broadway play
The Seven Year Itch, for which she was to receive a bonus of $100,000.
Monroe's next film was
River of No Return, which had been filmed prior to her suspension and featured
Robert Mitchum as her co-star. She called it a "Z-grade cowboy movie in which the acting finished second to the scenery and the CinemaScope process", although it was popular with audiences. The first film she made after returning to Fox was the musical
There's No Business Like Show Business, which she strongly disliked but the studio required her to do in exchange for dropping The Girl in Pink Tights. The musical was unsuccessful upon its release in December, and Monroe's performance was considered vulgar by many critics.
Posing for photographers while filming the subway grate scene for
The Seven Year Itch
in September 1954
In September 1954, Monroe began filming
Billy Wilder's comedy
The Seven Year Itch, in which she starred opposite
Tom Ewell as a woman who becomes the object of her married neighbor's sexual fantasies. Although the film was shot in Hollywood, the studio decided to generate advance publicity by staging the filming of a scene on
Lexington Avenue in New York. In the shoot, Monroe is standing on a subway grate with the air blowing up the skirt of her
white dress, which became one of the most famous scenes of her career. The shoot lasted for several hours and attracted a crowd of nearly 2,000 spectators, including professional photographers.
While the publicity stunt placed Monroe on international front pages, it also marked the end of her marriage to DiMaggio, who was furious about the stunt. The union had been troubled from the start by his jealousy and controlling attitude; Spoto and Banner have also asserted that he was physically abusive. After returning to Hollywood, Monroe hired famous attorney
Jerry Giesler and announced in October 1954 that she was filing for divorce. The Seven Year Itch was released the following June, and grossed over $4.5 million at the box office, making it one of the biggest commercial successes that year.
After filming for Itch wrapped in November, Monroe began a new battle for control over her career and left Hollywood for the East Coast, where she and photographer
Milton Greene founded their own production company, Marilyn Monroe Productions (MMP) – an action that has later been called "instrumental" in the collapse of the
[e] Announcing its foundation in a press conference in January 1955, Monroe stated that she was "tired of the same old sex roles. I want to do better things. People have scope, you know." She asserted that she was no longer under contract to Fox, as the studio had not fulfilled its duties, such as paying her the promised bonus for The Seven Year Itch. This began a year-long legal battle between her and the studio. The press largely ridiculed Monroe for her actions and she was parodied in Itch writer
Will Success Spoil Rock Hunter? (1955), in which her lookalike
Jayne Mansfield played a dumb actress who starts her own production company.
Monroe dedicated 1955 to studying her craft. She moved to New York and began taking acting classes with
Constance Collier and attending workshops on
method acting at the
Actors Studio, run by
Lee Strasberg. She sometimes jotted down private notes to herself of what she learned on a given day, acknowledging that Strasberg's observations about her in particular were important:
Why did it mean so much to me?... Strasberg makes me feel badly [that I was acting out of "fear"]... You must start to do things out of strength... by not looking for strength, but only looking and seeking technical ways and means.
She grew close to Strasberg and his wife Paula, receiving private lessons at their home due to her shyness, and soon became like a family member. She dismissed her old drama coach,
Natasha Lytess, and replaced her with Paula; the Strasbergs remained an important influence for the rest of her career. Monroe also started undergoing
psychoanalysis at the recommendation of Strasberg, who believed that an actor must confront their emotional traumas and use them in their performances.
In her private life, Monroe continued her relationship with DiMaggio despite the ongoing divorce proceedings; she also dated actor
Marlon Brando and playwright
 She had first been introduced to Miller by Kazan in the early 1950s.
 The affair between Monroe and Miller became increasingly serious after October 1955, when her divorce from DiMaggio was finalized, and Miller separated from his wife. The FBI also opened a file on her. The studio feared that Monroe would be blacklisted and urged her to end the affair, as Miller was being investigated by the
FBI for allegations of
communism and had been subpoenaed by the
House Un-American Activities Committee. Despite the risk to her career, Monroe refused to end the relationship, later calling the studio heads "born cowards".
By the end of the year, Monroe and Fox had come to an agreement about a new seven-year contract. It was clear that MMP would not be able to finance films alone, and the studio was eager to have Monroe working again. The contract required her to make four movies for Fox during the seven years. The studio would pay her $100,000 for each movie, and granted her the right to choose her own projects, directors and cinematographers. She would also be free to make one film with MMP per each completed film for Fox.
Critical acclaim and marriage to Arthur Miller (1956–1959)
Monroe began 1956 by announcing her win over 20th Century-Fox; the press, which had previously derided her, now wrote favorably about her decision to fight the studio.
Time called her a "shrewd businesswoman" and
Look predicted that the win would be "an example of the individual against the herd for years to come". In March, she officially changed her name to Marilyn Monroe. Her relationship with Miller prompted some negative comments from the press, including
Walter Winchell's statement that "America's best-known blonde moving picture star is now the darling of the left-wing intelligentsia." Monroe and Miller were married in a civil ceremony at the Westchester County Court in
White Plains, New York, on June 29, and two days later had a
Jewish ceremony at his agent's house at
Waccabuc, New York.
converted to Judaism with the marriage, which led Egypt to ban all of her films.
[g] The media saw the union as mismatched given her star image as a sex symbol and his position as an intellectual, as demonstrated by Variety's headline "Egghead Weds Hourglass".
Monroe's dramatic performance in
(1956) marked a departure from her earlier comedies.
Bus Stop was the first film that Monroe chose to make under the new contract; the movie was released in August 1956. She played Chérie, a saloon singer whose dreams of stardom are complicated by a naïve cowboy who falls in love with her. For the role, she learnt an
Ozark accent, chose costumes and make-up that lacked the glamour of her earlier films, and provided deliberately mediocre singing and dancing.
Joshua Logan agreed to direct, despite initially doubting her acting abilities and knowing of her reputation for being difficult. The filming took place in Idaho and Arizona in early 1956, with Monroe "technically in charge" as the head of MMP, occasionally making decisions on cinematography and with Logan adapting to her chronic lateness and perfectionism.
The experience changed Logan's opinion of Monroe, and he later compared her to
Charlie Chaplin in her ability to blend comedy and tragedy. Bus Stop became a box office success, grossing $4.25 million, and received mainly favorable reviews.
The Saturday Review of Literature wrote that Monroe's performance "effectively dispels once and for all the notion that she is merely a glamour personality" and Crowther proclaimed: "Hold on to your chairs, everybody, and get set for a rattling surprise. Marilyn Monroe has finally proved herself an actress." She received a
Golden Globe for Best Actress nomination for her performance.
In August 1956, Monroe began filming MMP's first independent production,
The Prince and the Showgirl, at
Pinewood Studios in England. It was based on
The Sleeping Prince, a play about an affair between a showgirl and a prince in the 1910s. The main roles had first been played on stage by
Laurence Olivier and
Vivien Leigh; he reprised his role and directed and co-produced the film. The production was complicated by conflicts between him and Monroe. He angered her with the patronizing statement "All you have to do is be sexy", and by wanting her to replicate Leigh's interpretation. He also disliked the constant presence of Paula Strasberg, Monroe's acting coach, on set.
In retaliation to what she considered Olivier's "condescending" behavior, Monroe started arriving late and became uncooperative, stating later that "if you don't respect your artists, they can't work well." Her drug use escalated, and according to Spoto she became pregnant and miscarried during the production. She also had arguments with Greene over how MMP should be run, including whether Miller should join the company. Despite the difficulties, the film was completed on schedule by the end of the year. It was released in June 1957 to mixed reviews, and proved unpopular with American audiences. It was better received in Europe, where she was awarded the Italian
David di Donatello and the French
Crystal Star awards, and was nominated for a
After returning to the United States, Monroe took an 18-month hiatus from work to concentrate on married life on the East Coast. She and Miller split their time between their Manhattan apartment and an eighteenth-century farmhouse that they purchased in
Roxbury, Connecticut; they spent the summer in
Amagansett, Long Island. She became pregnant in mid-1957, but it was
ectopic and had to be terminated. She suffered a miscarriage a year later. Her
gynecological problems were largely caused by
endometriosis, a disease from which she suffered throughout her adult life.
[h] Monroe was also briefly hospitalized during this time due to a barbiturate overdose. During the hiatus, she dismissed Greene from MMP and bought his share of the company as they could not settle their disagreements and she had begun to suspect that he was embezzling money from the company.
Monroe returned to Hollywood in July 1958 to act opposite
Jack Lemmon and
Tony Curtis in Billy Wilder's comedy on gender roles,
Some Like It Hot. Although she considered the role of Sugar Kane another "dumb blonde", she accepted it due to Miller's encouragement and the offer of receiving ten percent of the film's profits in addition to her standard pay. The difficulties during the film's production have since become "legendary". Monroe would demand dozens of re-takes, and could not remember her lines or act as directed – Curtis famously stated that kissing her was "like kissing
Hitler" due to the number of re-takes. Monroe herself privately likened the production to a sinking ship and commented on her co-stars and director saying "[but] why should I worry, I have no phallic symbol to lose."
 Many of the problems stemmed from a conflict between her and Wilder, who also had a reputation for being difficult, on how she should play the character. Monroe made Wilder angry by asking him to alter many of her scenes, which in turn made her stage fright worse, and it is suggested that she deliberately ruined several scenes to act them her way.
In the end, Wilder was happy with Monroe's performance, stating: "Anyone can remember lines, but it takes a real artist to come on the set and not know her lines and yet give the performance she did!" Despite the difficulties of its production, Some Like It Hot became a critical and commercial success when it was released in March 1959. Monroe's performance earned her a Golden Globe for Best Actress, and prompted Variety to call her "a comedienne with that combination of sex appeal and timing that just can't be beat".
 It has been voted one of the best films ever made in polls by the
American Film Institute and
Sight & Sound.
Career decline and personal difficulties (1960–1962)
After Some Like It Hot, Monroe took another hiatus until late 1959, when she returned to Hollywood and starred in the musical comedy
Let's Make Love, about an actress and a millionaire who fall in love when performing in a satirical play. She chose
George Cukor to direct and Miller re-wrote portions of the script, which she considered weak; she accepted the part solely because she was behind on her contract with Fox, having only made one of four promised films. The film's production was delayed by her frequent absences from the set. She had an affair with
Yves Montand, her co-star, which was widely reported by the press and used in the film's publicity campaign. Let's Make Love was unsuccessful upon its release in September 1960; Crowther described Monroe as appearing "rather untidy" and "lacking ... the old Monroe dynamism",
 and Hedda Hopper called the film "the most vulgar picture she's ever done".
Truman Capote lobbied for her to play Holly Golightly in
a film adaptation of
Breakfast at Tiffany's, but the role went to
Audrey Hepburn as its producers feared that Monroe would complicate the production.
The last film that Monroe completed was John Huston's
The Misfits, which Miller had written to provide her with a dramatic role. She played Roslyn, a recently divorced woman who becomes friends with three aging cowboys, played by
Eli Wallach and
Montgomery Clift. Its filming in the Nevada desert between July and November 1960 was again difficult. Monroe and Miller's four-year marriage was effectively over, and he began a new relationship with
Inge Morath. Monroe disliked that he had based her role partly on her life, and thought it inferior to the male roles; she also struggled with Miller's habit of re-writing scenes the night before filming. Her health was also failing: she was in pain from
gallstones, and her drug addiction was so severe that her make-up usually had to be applied while she was still asleep under the influence of barbiturates. In August, filming was halted for her to spend a week
detoxing in a Los Angeles hospital. Despite her problems, Huston stated that when Monroe was playing Roslyn, she "was not pretending to an emotion. It was the real thing. She would go deep down within herself and find it and bring it up into consciousness."
Monroe and Miller separated after filming wrapped up, and she was granted a
quick divorce in Mexico in January 1961. The Misfits was released the following month, but the movie failed at the box office. Its reviews were mixed, with Variety complaining of frequently "choppy" character development,
 and Bosley Crowther calling Monroe "completely blank and unfathomable" and stating that "unfortunately for the film's structure, everything turns upon her".
 Despite the film's initial failure, it has received more favorable reviews from critics and film scholars in the twenty-first century.
Geoff Andrew of the
British Film Institute has called it a classic,
 Huston scholar Tony Tracy has described Monroe's performance the "most mature interpretation of her career", and Geoffrey McNab of
The Independent has praised her for being "extraordinary" in portraying Roslyn's "power of empathy".
Monroe was next to star in a television adaptation of
W. Somerset Maugham's short story Rain for
NBC, but the project fell through as the network did not want to hire her choice of director, Lee Strasberg. Instead of working, she spent the first six months of 1961 preoccupied by health problems. Monroe underwent surgery for her endometriosis, had a
cholecystectomy, and spent four weeks in hospital care – including a brief stint in a
mental ward – for depression.
[i] She was helped by her ex-husband Joe DiMaggio, with whom she now rekindled a friendship. In spring 1961, Monroe also moved back to California after six years on the East Coast. She dated Frank Sinatra for several months, and in early 1962 purchased a house in
Brentwood, Los Angeles.

Something's Got to Give
. She was absent due to illness for most of the production and was fired by Fox in June 1962.
Monroe returned to the public eye in spring 1962: she received a "World Film Favorite" Golden Globe award and began to shoot a new film for 20th Century-Fox,
Something's Got to Give, a re-make of
My Favorite Wife (1940). It was to be co-produced by MMP, directed by George Cukor and to co-star
Dean Martin and
Cyd Charisse. Days before filming began, Monroe caught
sinusitis; despite medical advice to postpone the production, Fox began it as planned in late April. Monroe was too ill to work for the majority of the next six weeks, but despite confirmations by multiple doctors, the studio tried to put pressure on her by alleging publicly that she was faking it. On May 19, she took a break to sing "
Happy Birthday" on stage at President
John F. Kennedy's birthday celebration at
Madison Square Garden in New York. She drew attention with her costume: a beige, skintight dress covered in rhinestones, which made her appear nude.
[j] Monroe's trip to New York caused even more irritation for Fox executives, who had wanted her to cancel it.
Monroe next filmed a scene for Something's Got to Give in which she swam naked in a swimming pool. To generate advance publicity, the press was invited to take photographs of the scene, which were later published in Life; this was the first time that a major star had posed nude while at the height of their career. When she was again on sick leave for several days, Fox decided that it could not afford to have another film running behind schedule when it was already struggling to cover the rising costs of
Cleopatra (1963). On June 7, Fox fired Monroe and sued her for $750,000 in damages. She was replaced by
Lee Remick, but after Martin refused to make the film with anyone other than Monroe, Fox sued him as well and shut down the production. The studio blamed Monroe for the film's demise and began spreading negative publicity about her, even alleging that she was mentally disturbed.
Fox soon regretted its decision, and re-opened negotiations with Monroe later in June; a settlement about a new contract, including re-commencing Something's Got to Give and a starring role in the
What a Way to Go! (1964), was reached later that summer. To repair her public image, Monroe engaged in several publicity ventures, including interviews for Life and
Cosmopolitan and her first photo shoot for
Vogue. For Vogue, she and photographer
Bert Stern collaborated for two series of photographs, one a standard fashion editorial and another of her posing nude, which were both later published posthumously with the title
The Last Sitting. In the last weeks of her life, she was also planning on starring in a biopic of
