The Bellboy and the Playgirls(1962)

A very funny tale about a man with a theory about girls!

The bellboy aspires to be a private eye and is reading a book to learn the trade. The 'suspicious' activities of women in the hotel give him a chance to practice his skills. Surprise! They are representatives of a lingerie manufacturer. To investigate further, he poses as a potential buyer, and the women take turns modeling their wares. The film is a re-edited version of a West German film from 1958 originally titled “Mit Eva fing die Sünde an” with roughly 15 minutes of additional footage shot by Francis Ford Coppola and Jack Hill with nudity inserted for an American release in 1962. Coppola has since said that the project was "adding five three-minute nudie sketches in color to a stupid German movie that had been shot in black-and-white"
