Film / Prom Night III: The Last Kiss

Go To
Prom Night III: The Last Kiss is 1990 horror comedy film.

This installment is a continuation of the previous film. It was released Direct-to-Video as the previous film flopped theatrically, but performed well on home video.

Mary Lou manages to escape from the other side to the land of the living, and begins dating a student named Alex, offering her special brand of skills (read: murder) to help him through high school. But when he tries to break off with her due to all the bodies she leaves behind, all hell breaks loose (literally).

The film was written and co-directed by Ron Oliver, who had written the previous film and directed its reshoots. Peter Simpson, the producer of the previous two films, was the other co-director.


This film has the examples of:

  • Ambiguous Ending: Very much downplayed compared to most examples of the trope, but given the nature of Mary Lou's powers, as well as how it isn't quite explained, there is a chance that the ending Is only in Alex's head and is Mary Lou lashing out at his sanity in defeat.
  • Arc Number: The number 57 crops up a lot, since it's the year of Mary Lou's death.
  • Ascended Extra: Mary Lou is the driving force behind both this film and its predecessor, but she has far more screen-time here.
  • Asian and Nerdy: Played with. An Asian student is seen sobbing after not making the top of the honor roll.
  • Awesome Moments: Sarah fighting off the inhabitants of Hell with a flamethrower.
  • Boy Meets Ghoul
  • Continuity Snarl: Despite being a direct sequel to the previous film, there is absolutely no continuity with it whatsoever.
