John Sturges admitted to have made the movie for money only. He did not feel the story, the characters, the whole atmosphere. And, Laurence Harvey's mannerisms made the shooting very uncomfortable.
Martha Hyer says in her autobiography that playing love scenes with Laurence Harvey needed a strong stomach. According to her, he was in real life the same misfit he was in most of the films he played.
John Sturges intended to show in this movie women playing some kind of male characters.
