- Creator Backlash: Though Writer/Director Ron Oliver enjoyed working with the cast, he later wished that he'd chosen more age appropriate actors to portray the high school students.
- Keep Circulating the Tapes: The 2003 U.S. DVD release from Artisan (a double feature with part 4) contains the television edit, with alternate angles/takes and poorly dubbed-out profanity. The original edit is not legally available in the United States apart from the initial VHS release. Echo Bridge even released a triple feature DVD of the original Prom Night, Hello Mary Lou: Prom Night II and Prom Night IV: Deliver Us From Evil, skipping right over this film. This is also the only entry of the original series to not be available for streaming on Amazon Prime. It's possible the film is currently suffering from unspecified legal issues, and might even be in the same legal nightmare as Fright Night Part II, which had the same producer.
- The Australian DVD is currently the only English release of the original cut on that format (the German release also has it, but only with German audio). The English box set utilized the TV cut as well.
- The Other Darrin: Courtney Taylor replaces Lisa Schrage as Mary Lou.
- Troubled Production: Considering the film's low budget and pressure to get things finished as quickly and cheaply as possible, there were numerous issues the cast and crew encountered during production:
- Producer Jose Menendez was murdered by his two sons right as production was beginning, putting filming on hold for a couple weeks.
- Al Magliochetti, who did visual effects work on the film through VFX company Light and Motion, recalled numerous instances of a tense and confusing on-set atmosphere. For example, he did not get along with producer, co-director Peter Simpson, labeling him an uncivilized thug and one of the nastiest producers he'd ever worked with. He described one instance where Simpson reduced actress Courtney Taylor (Mary Lou) to tears after making a crude comment about her chest.
- Editor Nick Rotundo was also the cause of much tension, as Magliochetti recalled that Rotundo would often try to override the wishes of director Ron Oliver and the VFX department, simply doing whatever he wanted with the picture. After Oliver exploded at Magliochetti over an unauthorized change, he simply showed Oliver the instructions Rotundo had given him, causing Oliver to realize the source of the problem.
- You Look Familiar: Brock Simpson, who played Josh in the previous film (and young Nick in the original), appears as Larry the Cop.
