Caitlin O’Heaney, who starred as the stalked bride to be in the cult slasher film He Knows You’re Alone and as a lounge singer and spy in the Donald P. Bellisario-created adventure series Tales of the Gold Monkey, has died. She was 73.

O’Heaney died May 18 in Westchester County in New York, her friend Peter Davis told The Hollywood Reporter. They recently worked together on the short film Faith and Forgiveness. No cause of death was revealed.

Trained at Julliard under John Houseman and Michael Kahn, O’Heaney also worked with Katharine Hepburn on Broadway, played a 1930s Hollywood actress for Woody Allen in A Midsummer Night’s Sex Comedy (1982) and starred as Snow White on the first season of the 1987-88 ABC sitcom The Charmings.

The green-eyed, auburn-haired O’Heaney portrayed Amy Jensen, a woman menaced by a bride-obsessed killer, in He Knows You’re Alone (1980), an independent film picked up by MGM. Director Armand Mastroianni said he looked at more than 4,000 photos and interviewed more than 100 actresses before selecting her for the part.

And on the 1982-83 series Tales of the Gold Monkey, set in in 1938 in the South Pacific, she portrayed the American spy Sarah Stickney White, the love interest of fighter pilot Jake Cutter (Stephen Collins).
