Artist Disillusionment: Surprisingly averted, given that Ted White (Jason) hated the experience, butted heads with director Joe Zito, and wasn't too fond of the finished product (or the slasher genre in general, for that matter). He actually enjoys interacting with fans on the convention circuit and has even said that, in over 50 years in the industry, he's never met nicer people than the Friday the 13th fans who approach him.
Magnum Opus Dissonance / Old Shame: A two'fer. Ted White is best-known for this film and is considered by many fans to be one of the best Jasons; Mister White has no love for the film or even the slasher genre in general. Due to this and him and director Joe Zitto arguing all the time, he demanded his name be taken off the film, which is why he's uncredited and why he turned down the chance to play Jason in following sequels. After positive experiences in the convention circuits, he admited he regrets turning down the offers.
Old Shame is apparently averted in the case of Corey Feldman, who played Tommy. During a commentary interview as part of a "Making of" documentary, Feldman has said that he would love to play Tommy one more time in a movie that ignored the character's appearances in Parts V and VI, in order to have one more showdown with Jason (similar to what Jamie Lee Curtis did with Halloween H20).
Money, Dear Boy: The reason Ted White took the part and the reason he started appearing at horror conventions after refusing to do so for over two decades. He has warmed up to the role after meeting the fans, however.
Screwed by the Lawyers: The music in the Crispin Glover dance scene was originally AC/DC's Back in Black, but they had to dub it over with the Lion song Love is a Lie to avoid getting into a lawsuit with the former.
Throw It In!: The scene where Jason grabs Tommy. Zito told Feldman when Ted White (Jason) was gonna grab him. Feldman was prepared for it, but the grab was delayed for a while. When Feldman was about to wonder what was going on White burst through and grabbed him. Tommy's screaming was really Feldman screaming for real as he didn't see it coming.
What Could Have Been: The original script called for Tommy to cut Jason's head off to kill him, but this was changed in case they wanted Jason to return.
