Several contemporary reviewers mentioned that, although the film was set in the 1930s, Capucine seemed to be wearing contemporary (1962) fashions. Director Edward Dmytryk stated that it was because she was the "protégé" (i.e., live-in girlfriend) of producer Charles K.

According to Penny Stallings' 'Flesh and Fantasy', when Barbara Stanwyck first encountered Laurence Harvey on the set lounging in his gold brocade bathrobe and drinking champagne, she walked up to him and said, "All right, Larry, let's go! Get your ass in gear. We've got a picture to make, and I don't have time for prima donnas!" After a moment of silence, this struck Harvey as highly amusing, and he burst into laughter. He and Stanwyck immediately became friends.
During the filming, Capucine objected to filming kissing scenes with Laurence Harvey, feeling that he was not manly enough for her. Harvey reportedly replied, "Perhaps if you were more of a woman, I would be more of a man. Honey, kissing you is like kissing the side of a beer bottle."
