The Misfits
In 1960, Marilyn began filming The Misfits, with Clark Gable and Montgomery Clift. Written by her husband, Arthur Miller, the filming was troubled. Problems on the set were largely caused by the dissolution of her marriage to Miller, her demanding rewrites of numerous scenes, and Gable’s own ill health. It was to be his last film. Clark Gable died just days after the film was completed in November, 1960.
Although nobody knew it at the time, it was also the last film Marilyn Monroe completed during her lifetime. Following its completion Monroe went to Mexico to obtain a quick divorce from Miller, abandoned her Judaism studies and practice, and entered a period of steadily declining health, both mental and physical. She underwent surgery for her endometriosis and other related problems and spent hospitalized for mental health issues. She began work on other projects, but health problems prevented their completion and they were abandoned.
