Prom Night III: The Last Kiss is a 1990 Canadian slasher horror comedy film and the third in the Prom Night franchise, continuing the storyline involving the murderous ghoul Mary Lou Maloney. This is the only entry to depart from the strictly horror genre of the series, and is instead a spoof of the previous films. It was released in theaters on June 1, 1990. This film was followed by a third sequel, titled Prom Night IV: Deliver Us from Evil.
