Censorship At the time, the Motion Picture Production Code prohibited the portrayal of illicit sex as harmless or positive. For the film to be approved under the Code, a line had to be inserted in post-production in which Chris expresses his regret at having had premarital sex with Alice. As Niven was not available, the line was done as a voice-over impression of Niven by voice actor Allen Swift.
