In an interview with American Movie Classics just before his death, Anthony Perkins admitted he was not up to the task of directing this film, feeling his technical knowledge to be too limited.
Anthony Perkins originally wanted to use a stunt woman for the scene where Duane throws Red out of the motel room. Juliette Cummins convinced Perkins to not use a stunt double and did her own stunt for that scene.
Actress Juliette Cummins was nearly fired by director Anthony Perkins after making an unintentional joke about his homosexuality.
