Hepburn was offered the role of Emma Jacklin, but only wanted to do the film with Grace Kelly as her co-star. Kelly declined the film, and all others, due to the people in Monoco not wanting her to be an actress. So Audrey did not do the film either.

Turned down the role because she was Princess of Monaco and had run into difficulties with her subjects earlier when Alfred Hitchcock and she had planned to do "Marnie" together.
