This Czechoslovakian production wasn’t the first non-pornographic film to depict sexual intercourse, but it is the first movie to feature an actress, Hedy Lamarr, in her star-making role, simulating an orgasm onscreen. Lamarr’s non-sexual nude caused censorship, bans and denouncements of the film from the U.S. Department of the Treasury, Adolph Hitler and Pope Pius XII. However, the close-ups on the facial expressions of a woman in bliss were certainly as objectionable, if not more so, for the time.
