Trivia: A fan theory on Reddit suggest that Roy Burns was possessed by the spirit of Jason Voorhees. There is some credence to this theory considering that the murders Roy committed would require inhuman strength, he broke down a solid wooden door by just walking through it and when he got hit by a tractor, he got back up very quickly. How he got possessed by Jason however has never been explained.
Trivia: Initially, Corey Feldman was asked to reprise his role as Tommy Jarvis, but since he was busy shooting "The Goonies," the character was re-written to be a few years older, and John Shepherd was cast. Feldman did appear in a brief cameo during the opening dream sequence.
Trivia: There are three different hockey masks used either in this film or its advertisements. The first is the one that the Jason impostor (Roy) wears. It has two blue triangles below the eyes. The second is the one the real Jason wears when Tommy sees him in the hospital room at the end, with the red triangles. The third is featured on the poster. It has an un-holy amount of breathing holes on it. (01:23:00 - 01:27:10)
Trivia: Director Danny Steinmann is more infamous for directing pornography. This is why there's more sex in this film than previously. He also didn't care much for directing the actors, so they often had to improvise their scenes.
Trivia: Since Jason is killed at the end of the fourth film, the idea with this movie was to take the series in a new direction by having a different man become the killer, and to have Tommy become the killer in the sixth film, which is why Jason doesn't appear anywhere here, except in Tommy's dreams. This plan was scrapped, however, when Part 5 underperformed at the box office and audiences at the time were unhappy that Jason wasn't in it, so for the sixth film they brought Jason back.
Trivia: Tommy Jarvis says only 24 words throughout the entire film.
Trivia: Even ignoring the "deaths" that occur in Tommy's dreams, this film still had, at the time, the highest body count of any movie in the series.
Trivia: Originally, the film was supposed to pick up where the ending of the previous film left off. Tommy Jarvis is taken to the same hospital as Jason's body. While trying to get to the morgue, he murders seven people on the staff. When he arrives, he finds Jason's body rising from the table. The adult Tommy then wakes up in the van, on his way to Pinehurst.
