Famed director Alfred Hitchcock is the master of suspense and the grandfather of the slasher movie. While Psycho (1960) is light on gore and sex, for its time it was a mind-blower. The simple premise is that Janet Leigh has stolen $40,000 and is hiding out at a cheap motel waiting for her lover. Too bad for her it's the Bates Motel, with mama's boy Anthony Perkins as its knife-happy proprietor. Janet gets offed in one of the scariest yet sexiest shower scenes in a film history rife with them. She's completely nude, but Hitchcock's quick editing makes it difficult to catch more than a hip and side of boob, but an out-of-focus nipple will reward the eagle-eyed. Yes, Psycho will drive you mad with desire.
