This was the first movie in which a mainstream American actress (Jayne Mansfield) appeared nude in several revealing scenes). It reportedly took some imbibing of champagne on Mansfield's part to get her out of her clothes the first time, although her fellow actors revealed in later interviews that she seemed to enjoy being naked on set and the attention she got so much, especially from men, that she started traipsing around between scenes. In fact, a photo in Kenneth Anger's book "Hollywood Babylon II" shows Mansfield on the set completely nude chatting with the crew.
During the filming of Jayne Mansfield's nude scenes, Playboy sent a photographer to take still shots which were published in the magazine to promote the movie. Playboy published its behind-the-scenes images in the June 1963 issue, promising "The Nudest Jayne Mansfield" on the cover. Publisher Hugh Hefner was then arrested by Chicago vice squad. The city based its complaint on two "particularly obscene" images showing Mansfield lying naked on a bed with a fully clothed man. But it ended up a mistrial.
During the ocean cruise, Sandy (Jayne Mansfield) sends a telegram announcing her pregnancy to her parents, Mr. and Mrs. Harry Peers in Texas. The Peers were Mansfield's actual mother and step-father.
Despite being banned in some cities (or perhaps because of it), the film was a hit, and helped to put Jayne Mansfield on the Top 20 List of Box Office Attractions for 1963.
Jayne Mansfield agreed to make her topless debut in this film - the first nude scene in U.S. films since 1934 because the misbegotten Will Hays "Production Code" outlawed it - because she was in a career slump at the time. She hadn't had a hit since Will Success Spoil Rock Hunter? (1957), and her longtime studio was getting fed up. Fox dropped her contract after yet another dud, the historical riff It Happened in Athens (1962). But the nudity didn't help her career. Though it did indicate where films were heading in respect to the policy against nudity. From that point on, U.S. studios started adding more and more nudity, ignoring the weakening power of the Production Code and the puritanical government group behind it.
