  • Tom Hanks makes his Big Screen debut in a small role...producers cut out his death scene after they took a liking to him off screen...His character was a psychology student.
  • The film was inspirational to Kevin Williamson (Scream), Sream 2's opening scene is very reminecent to this films, in which a female is murdered at a movie theater. In an early draft of the script, randy meeks mentions the similarities.
