Trivia: The big fight scene is spoofed in "South Park" when the crippled kids Timmy and Jimmy fight, instead of the film's Nada and Frank. The episode is called "Cripple Fight".
Trivia: Check out the nurse that wakes Kristen up at the school infirmary. It is Robert Englund, out of his Freddy make-up. After Kristen wakes up, it is a different person.
Trivia: When Chucky is running behind Maggie, many children and child relatives of cast and crew were filmed doing the run while dressed up as Chucky, including Alex Vincent's younger sister, since it would have been impossible for the animatronic Chucky to run across screen like that. However, it is unknown which child ultimately was used in the final cut.
Trivia: The horn sound that is continually made by Leviathan is Morse code for "God".
Trivia: During the filming of the movie, Kane Hodder (the actor who plays Jason) was returning to his trailer one night after filming, still in his Jason costume. His trailer was approximately one mile down a dark, dirt back-road. Exhausted from filming, Kane decided to take a shortcut through the woods surrounding the area. While in the woods, he encountered a local resident, who asked Kane if he was filming the new Friday movie. Thinking it a rather foolish question, given that he was still in his Jason costume, mask and all, Kane did not answer. After the young man tried to communicate with him several more times, Kane remained staring and silent, until he lunged for the man and groaned, sending the man in an absolute panic. He was so terrified that he fell several times and struggled to his feet, screaming as he ran away. The next morning, Kane Hodder was informed that the Sheriff would be by the set later in the day for questioning, but the Sheriff never came. Definitely a hilarious, if not terrifying joke.
Trivia: Director Tom Holland was asked to direct this movie following his success with the first movie. Actors Chris Sarandon, Amanda Bearse and Stephen Geoffrey's were all offered to reprise their character's roles. All four had turned them down. Tom and Chris were both working together on the movie Child's Play. Amanda didn't like the material and was busy appearing in the TV show Married...With Children. Stephen was offered the choice to be in this movie or 976-Evil. Stephen, like Amanda, didn't like the material and hated the script and chose the latter movie. Only William Ragsdale and Roddy McDowall appeared in this movie as their original characters.
Trivia: At the end of the movie, the Carol-Anne that Pat is holding is really a double, because Heather O'Rourke died from intestinal stenosis, shortly before the movie was finished.
Trivia: Jeremy Irons kept track of his characters by playing one with his weight on the balls of his feet, and the other with his weight on his heels.
Trivia: The role of Klownzilla the King Klown was played by Charles Chiodo, who helped write the story.
Trivia: The demon effects were done by Carlo Rambaldi, who is arguably most famous for creating the design of the benevolent titular character from Steven Spielberg's "E.T."
Trivia: Almost all of the characters are named after real-life popular Hollywood actors and directors from the era: Molly (Molly Ringwald), Sean (Sean Penn), Uncle John (John Hughes), TC (Tom Cruise), Ally (Ally Sheedy), Chuck and Emilio (Charlie Sheen and Emilio Estevez), Anthony (Anthony Michael Hall), Judd (Judd Nelson), Demi (Demi Moore), Lea (Lea Thompson), Brooke and Jodi Shote (Brooke Shields and Jodi Foster), Phoebe (Phoebe Cates), etc.
Trivia: The film's original title was "Red Rain" and the Peter Gabriel song of the same name was meant to be featured in the film. However, they couldn't get the rights to feature the song, so the song "Red Harvest" was commissioned and written specifically for the film. Shortly before the film's release, the studio decided that the title "Red Rain" no longer made any sense without the Gabriel song in the movie, and instead retitled the film "Jack's Back."
