Trivia / Hello Mary Lou: Prom Night II

  • Box Office Bomb: Earned only $2,683,519 on a $2 million budget, but was a success on home video. However, this only ensured the next two sequels would go direct-to-video.
  • Executive Meddling: Producer Peter Simpson was unhappy with the original cut, feeling it wasn't scary enough, and ordered 1/3 of the movie to be reshot under the direction of screenwriter Ron Oliver, who (at that time) had never directed a movie before.
    • Also the distributor had the rights to the original Prom Night, and chose to make this film an In-Name-Only sequel to it at the last minute. Its original title was The Haunting of Hamilton High.
  • Follow the Leader: The film leans towards supernatural slasher genre á la Elm Street.
  • Germans Love David Hasselhoff: According to screenwriter Ron Oliver, the film received much better critical and audience reception in the US than its native Canada.
