Rob makes mention that he is there looking for the man who killed his sister. His sister was in part 2. She was Sandra, who was speared in bed after having sex.

Body count is 13.

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.

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.
