He Knows You're Alone (1980)
He Knows You're Alone is a 1980 American slasher film directed by Armand Mastroianni, written by Scott Parker and edited by George Norris. It was one of the first horror films to be influenced by the success of 1978's Halloween and shares a number of similarities with that previous hit. Although appearing in only a small role, this is Tom Hanks' film debut.
