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 all the attention she got, especially from men, that she started traipsing around in the buff between scenes. In fact, a photo in Kenneth Anger's book "Hollywood Babylon II" shows a completely-nude Mansfield 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 nude on a bed with a fully-clothed man. 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 of Texas. The Peers were Mansfield's actual mother and stepfather.
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.
During a wedding shower, the ship's effeminate hairdresser Babette (female impersonator T.C. Jones) mimics Jayne Mansfield, much to Sandy's (Mansfield) delight.
