Trivia: The TV edit of the film differs widely from the theatrical release - lots of footage was purposely edited out, such as when the dead Norwegian on the table blinks, and there is also a narration. Director John Carpenter has publicly stated that he finds the TV edit embarrassing and a disgrace to his movie.
Trivia: Craig T. Nelson was originally cast as Carla's boyfriend, Jerry, but his casting was vetoed by producer Harold Schneider, despite director Sidney J. Furie's insistence. Nelson instead famously starred in contemporaneous supernatural hit Poltergeist (1982).
