Who Killed Teddy Bear is a 1965 American neo-noir crime thriller film,[3] directed by Joseph Cates and starring Sal Mineo, Juliet Prowse, Jan Murray and Elaine Stritch.

Norah Dain, a nightclub disc jockey and aspiring actress living alone in a Manhattan apartment, receives a series of obscene phone calls from someone who seems to be watching her on a daily basis.

A police detective, Lt. Dave Madden, whose own wife was raped and murdered, takes a personal interest in Norah and her case.

Lawrence is unable to have a normal romantic or sexual relationship due to his guilt over the accident and his duty to look after Edie following the death of their parents.

He tries to get rid of his frustration by visiting adult bookstores and movies in Times Square, but still is obsessed with watching and calling Norah.

Instead, she is friendly to him and even attracted to him, complimenting him on his body when they meet at the gym, and offering to stay late after work to teach him to dance.

Director Joseph Cates envisioned the film as a noir thriller that was meant to appeal to the exploitation crowd.

[7] A scene of the film required Mineo's character to imply he was masturbating, but no nudity could be shown due to censors.

"[8] Set in New York City, the film was shot on location in Manhattan and features footage of Times Square.

[15] In a retrospective review, Anton Bitel of Channel 4 wrote: "The film’s sexual panic captures perfectly the mood between the repressive 1950s and the liberated 1970s – and for those with an interest in cinema history, Teddy Bear represents an important missing link between, on the one hand, Peeping Tom (1960), Psycho (1960), and the nascent Italian giallo genre, and on the other hand, Black Christmas (1974), Taxi Driver (1976), and the American slasher genre.
