Marilyn Monroe

Some Like it Hot became a resounding success, and was nominated for six Academy Awards. Monroe was acclaimed for her performance and won the Golden Globe Award for Best Actress - Motion Picture Musical or Comedy. Wilder commented that the film was the biggest success he had ever been associated with. He discussed the problems he encountered during filming, saying "Marilyn was so difficult because she was totally unpredictable. I never knew what kind of day we were going to have... would she be cooperative or obstructive?" He had little patience with her method-acting technique and said that instead of going to the Actors Studio "she should have gone to a train-engineer's school ... to learn something about arriving on schedule." Wilder had become ill during filming, and explained, "We were in mid-flight – and there was a nut on the plane." In hindsight, he discussed Monroe's "certain indefinable magic" and "absolute genius as a comic actress."
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.
