Let’s Make Love (George Cukor, 1960) is a musical comedy film made by 20th Century Fox. It was produced by Jerry Wald from a screenplay by Norman Krasna, Hal Kanter and Arthur Miller. It starred Marilyn Monroe, Yves Montand and Tony Randall. It would be Monroe’s last musical film performance.
Norman Krasna was inspired to write the script after seeing Burt Lancaster do a dance at a Writers Guild award ceremony and receiving a loud applause. He came up with the idea of a story about a very wealthy playboy like Jock Whitney who hears about a company putting on a show that made fun of him and becomes enamoured of the theatre and a girl in the play.
Krasna felt that only three actors were suitable to play the male lead — Gary Cooper, James Stewart and Gregory Peck — because all were so obviously not musical performers, making it funny if they sung and danced. Peck agreed to play the lead, and then Marilyn Monroe was signed opposite him, even though Krasna would have preferred Cyd Charisse.
Arthur Miller revised the script so that more emphasis was given to Monroe, his wife. This led to Peck dropping out. Rock Hudson was considered an ideal replacement based on his ability to play comedy, but Universal would not release him. So, Montand was cast instead after starring in The Crucible (Raymond Rouleau, 1957), based on a play also written by Miller. That pleased Monroe, who wanted Montand for the part. Krasna felt he was miscast because he could actually sing and dance, and so ruined the joke, but Monroe was enthusiastic about Montand. The two stars wound up having an affair during the making of the film.
