When a Stranger Calls is a 2006 American psychological horror film directed by Simon West and written by Jake Wade Wall. The film stars Camilla Belle, Brian Geraghty, Katie Cassidy, Tessa Thompson and Clark Gregg. Belle plays a babysitter who starts to receive threatening phone calls from an unidentified stranger, played by both Tommy Flanagan and Lance Henriksen. It is a remake of Fred Walton's 1979 horror film of the same name, which became a cult classic for its opening 20 minutes, which this remake extends to a feature-length film.
The film was theatrically released on February 3, 2006. It was panned by critics but was a moderate box office success, grossing $67.1 million worldwide on a $15 million budget.
