Trivia: Peter Barton was hesitant when it came time to do his death scene, as he was previously burned by a magnesium flare doing a stunt on a previous film and required multiple surgeries afterwards. Sensing Peter's hesitation, Ted White requested that a pad be placed behind Peter's head when he was slammed into the shower wall.
Trivia: When Judie Aronson, who plays Samantha, was filming the scene in the raft where she gets killed, they were doing so many takes. She was wet and cold and wanted to warm up. The director refused until he got the shot he wanted which made Judie cry and freak out. Ted White, who played Jason, was so upset about this that he demanded they get her a blanket and let her get warmed up or he would walk off the set and not come back. Needless to say, Judie got warmed up very quickly.
Trivia: Body count is 13.
Trivia: Ted White, who plays Jason, refused to talk to the other actors on the set, because he thought it would diminish their fear of Jason.
Trivia: Tom Savini, who did the effects for the original film, returned to do the effects for this movie. As Savini had "created Jason" by doing the effects for the first movie, he felt it was appropriate that he should also be the one to definitively "kill Jason," as this was originally intended to be the final film.
Trivia: An early concept for the film was that Tommy was going to dabble in inventing gizmos and gadgets, which would have paid off at the end of the movie, as he would use them against Jason. One early concept was that Tommy would invent a weapon using parts of a microwave oven, and would use it to blow apart Jason's head during the final battle. Eventually, he was instead reworked into a monster fanatic who made creature masks.
