Roman Polanski's adaptation of Ira Levin's novel holds up today because, when it comes to the real source of its scares—the paranoia and isolation big cities breed—nothing has changed.

Mia Farrow plays Rosemary, the bewildered outsider tortured in the private space of her high-rise apartment and pregnancy. John Cassavetes exudes slime as the narcissitic husband and wannabe actor who's seduced into darkness by the sweet (ahem) elderly couple next door.

The second—and best—part of Polanski's Apartment Trilogy builds terror by degrees. Like the frog in the slowly boiling pot of water, you don't know it's too late until you're already doomed. For every city-dweller who's ever wondered about his or her neighbors, there's something terrifying waiting in Rosemary's Baby. —GT
