Marilyn Monroe

Let's Make Love and the Misfits
By this time, Monroe had only completed one film, Bus Stop, under her four-picture contract with 20th Century Fox. She agreed to appear in Let's Make Love, which was to be directed by George Cukor, but she was not satisfied with the script, and Arthur Miller rewrote it. Gregory Peck was originally cast in the male lead role, but he refused the role after Miller's rewrite; Cary Grant, Charlton Heston, Yul Brynner and Rock Hudson also refused the role before it was offered to Yves Montand. Monroe and Miller befriended Montand and his wife, actress Simone Signoret, and filming progressed well until Miller was required to travel to Europe on business. Monroe began to leave the film set early and on several occasions failed to attend, but her attitude improved after Montand confronted her. Signoret returned to Europe to make a film, and Monroe and Montand began a brief affair that ended when Montand refused to leave Signoret. The film was not a critical or commercial success.
Monroe's health deteriorated during this period, and she began to see a Los Angeles psychiatrist, Dr. Ralph Greenson. He later recalled that during this time she frequently complained of insomnia, and told Greenson that she visited several medical doctors to obtain what Greenson considered an excessive variety of drugs. He concluded that she was progressing to the point of addiction, but also noted that she could give up the drugs for extended periods without suffering any withdrawal symptoms. According to Greenson, the marriage between Miller and Monroe was strained; he said that Miller appeared to genuinely care for Monroe and was willing to help her, but that Monroe rebuffed while also expressing resentment towards him for not doing more to help her. Greenson stated that his main objective at the time was to enforce a drastic reduction in Monroe's drug intake.
In 1956 Arthur Miller had lived briefly in Nevada and wrote a short story about some of the local people he had become acquainted with, a divorced woman and some aging cowboys. By 1960 he had developed the short story into a screenplay, and envisaged it as containing a suitable role for Monroe. It became her last completed film. The Misfits, directed by John Huston and costarring Clark Gable, Montgomery Clift, Eli Wallach and Thelma Ritter. Shooting commenced in July 1960, with most taking place in the hot Northern Nevada desert. Monroe was frequently ill and unable to perform, and away from the influence of Dr. Greenson, she had resumed her consumption of sleeping pills and alcohol. A visitor to the set, Susan Strasberg, later described Monroe as "mortally injured in some way," and in August, Monroe was rushed to Los Angeles where she was hospitalized for ten days. Newspapers reported that she had been near death, although the nature of her illness was not disclosed. Louella Parsons wrote in her newspaper column that Monroe was "a very sick girl, much sicker than at first believed", and disclosed that she was being treated by a psychiatrist. Monroe returned to Nevada and completed the film, but she became hostile towards Arthur Miller, and public arguments were reported by the press. Making the film had proved to be an arduous experience for the actors; in addition to Monroe's distress, Montgomery Clift had frequently been unable to perform due to illness, and by the final day of shooting, Thelma Ritter was in hospital suffering from exhaustion. Gable, commenting that he felt unwell, left the set without attending the wrap party. Monroe and Miller returned to New York on separate flights.
