Handed the exploitive title Cat People, RKO producer Val Lewton opted for a thinking man's thriller--a psychological mood piece, more reliant on suspense and suggestion than overt "scare stuff". Simone Simon plays an enigmatic young fashion artist who is curiously affected by the panther cage at the central park zoo. She falls in love with handsome Kent Smith, but loses him to Jane Randolph. After a chance confrontation with a bizarre stranger at a restaurant, Simon becomes obsessed with the notion that she's a Cat Woman--a member of an ancient Serbian tribe that metamorphoses into panthers whenever aroused by jealousy. She begins stalking her rival Randolph, terrifying the latter in the film's most memorable scene, set in an indoor swimming pool at midnight. Psychiatrist Tom Conway scoffs at the Cat Woman legend--until he recoils in horror after kissing Simon. If the film's main set looks familiar, it is because it was built for Orson Welles' The Magnificent Ambersons (Lewton later used the same set for his The Seventh Victim). Cat People was remade by director Paul Schrader in 1982.
