"Who Killed Teddy Bear?" is a 1965 British-American neo-noir thriller film, directed by Joseph Cates and starring Sal Mineo, Juliet Prowse, and Jan Murray. The movie follows the story of a nightclub deejay, Norah Dain (played by Juliet Prowse), who starts receiving disturbing and harassing phone calls from an unknown man. She reports the situation to the police, and detective Lt. Dave Madden (played by Jan Murray) takes charge of the case.
As Dave investigates, he discovers that Norah's stalker is more than just a harmless nuisance. The man, who calls himself "The Nymph," is a deeply disturbed individual who becomes increasingly obsessed with Norah and starts leaving her obscene gifts. Dave soon realizes that The Nymph is fixated on a Teddy bear, which becomes the central object of the investigation. As he delves deeper into the case, Dave must confront his own inner demons and compulsions, which threaten to compromise his judgment and his relationship with Norah.
The film is notable for its frank and explicit portrayal of sexual perversion and mental illness, which were considered taboo subjects at the time of its release. The movie also features a haunting jazz score by veteran composer and arranger Quincy Jones. "Who Killed Teddy Bear?" was initially overlooked by critics, but has since gained a cult following for its daring and provocative themes, as well as for the performances of its lead actors.
