During one scene with Burt Lancaster, Corinne Calvet felt nauseated and threw up on her leading man. She was not able to film anything else that day. She remained grateful to the actor that he never mentioned it after she returned and gave her suggestions and encouragement. She credits him for her success in Hollywood.
Hal Wallis and screenwriter of "Rope of Sand" saw it as a re-teaming of Ingrid Bergman and Humphrey Bogart. The producer of "Casablanca" did not get the stars but managed to recruit supporting players Claude Rains, Paul Henried, and Peter Lorre.
In 1984 Burt Lancaster said, " When I think of my least favorite [picture), I think of "Rope of Sand." I did that thing under great duress. I hated it."
According to Corinne Calvet's autobiography, "Has Corinne Been a Good Girl?," Hal Wallis demanded that she have sex with him in exchange for her starring in this movie. But she refused, saying she was a married woman. So Wallis dropped her option in 1953. To avenge herself, she had sex with him while she was sick. The next day, Wallis developed strep throat. Calvet sent him four dozen roses with a get-well-soon card and a note: "Next time, I'll give you something worse. Best wishes for your recovery."
In her autobiography, Corinne Calvet confesses that she did not understand what William Dieterle said, because of his heavy German accent. So she asked her co-star Burt Lancaster to translate for her.
