At one point the film was called "A Letter to Four Wives". Upon submitting the adapted screenplay to 20th Century-Fox chief
Darryl F. Zanuck,
Joseph L. Mankiewicz mentioned that he found it too long and asked how he felt the movie could be shortened. "Take out one of the wives," Zanuck replied. Originally, the movie would have featured
Anne Baxter as the fourth wife. Zanuck didn't feel Baxter's segment was as strong as the other three, so that one was cut.
