Based on Henry James's The Turn of the Screw, this creepy but ultimately perplexing thriller was one of the first films designed to scare you without showing, say, severed limbs and nonstop gore. The Innocents features a wide-eyed Deborah Kerr as a governess sent to a stately manor where she will care for two children. When they start communicating with ghosts, demons, dead people, the devil -- what they are, we'll never find it -- the poor governess comes unhinged. Not altogether frightening, but it has a few creep-out moments that mostly redeem its totally ambiguous ending.
