In his interview with François Truffaut, Alfred Hitchcock said he was so impressed with the performance of Anita Björk in Miss Julie (1951) that he hired her for this movie. However, when she arrived in Hollywood, Bjork brought her lover, writer Stig Dagerman, and their baby daughter. Since they were not married, Warner Bros. insisted that Hitchcock find another actress for the role of Ruth Grandfort, in this case Anne Baxter.
Montgomery Clift drank during the shooting and his eyes appear glazed during the ferry scene. Hitchcock was a very non-confrontational director and delegated an assistant director and Karl Malden to talk to the actor about it.
