Trivia: The movie ends with a shot of Mrs. Voorhees old wrinkled head on Jason's shrine. Originally her head was supposed to open its eyes, and smile. Steve Miner comments on commentary how he decided to get rid of the idea, as he felt it would make the movie come across as more cheap and hokey than normal.Hamster
Trivia: An actor/stuntman named Steve Dash actually played Jason in almost every scene, but was crestfallen when he found out he wouldn't be given on-screen credit for the role. Due to some studio red-tape, the actor credited for portraying Jason was Warrington Gillette, a stand-in who only appeared on-screen for a brief instance. (Gillette portrayed the "Unmasked Jason" under heavy makeup, who leaps through the window at the end of the film and is only on-screen for about 20 seconds.) Dash was understandably upset, as he put in almost all the work to create and play the character, but got no reward and was only credited as being Jason's stunt-double. When archival footage from this film was re-used in the next two installments in flashback, Dash was finally given the proper credit he deserved and was given sole credit for portraying Jason via archival footage.
