There was a comic book that bridged the gap between Friday the 13th Part VIII: Jason Takes Manhattan and this film. It followed Jason after he was dipped in toxic waste in a New York City sewer, and his killing spree all the way back to Camp Crystal Lake. It also explains why the FBI has a task force specifically for Jason.
The Necronomicon found in the Voorhees house is a prop created by Tom Sullivan for The Evil Dead and Evil Dead II. Sam Raimi sent a letter asking Sullivan to forgive him for not asking permission to borrow Sullivan's Evil Dead II props for this film. Tom Sullivan said he was not paid and would never again loan out props without granting permission.
Jason's heart was used in From Dusk Till Dawn as Monkey Man's heart.
In addition to his roles as Jason and the Security Guard, Kane Hodder also played Freddy Krueger's arm in the final scene.
One early concept for this movie was "Jason Goes To L.A" in which two rival gangs would be fighting; when Jason would show up and start murdering them. This would force the rival gangs to band together to defeat Jason.
The crate in the basement of the Voorhees house was a prop from the story "The Crate" from Creepshow.
The jungle gym in front of the Voorhees house was also used in The Birds.
At the end of the film, when the portal to Hell opens, Freddy Krueger's glove emerges to snatch Jason's hockey mask. If one accepts that Freddy was in Hell following his defeat in Freddy's Dead: The Final Nightmare (1991) (which was released in 1991 but actually set in the future), interesting timeline clues emerge. Namely, "Freddy's Dead" took place (according to the beginning crawl) "ten years from now". As noted, Freddy's Dead: The Final Nightmare (1991) came out in 1991. However, the "Nightmare on Elm Street" Companion website opted to interpret "10 Years from Today" as 10 years from 1989 (events of the prior film to the "Final Nightmare", A Nightmare on Elm Street 5: The Dream Child (1989)). In any event, if "Jason Goes To Hell" follows the events of "Freddy's Dead", then it must take place in either 1999 or 2001.
The original title of the movie was "Friday the 13th Part IX: The Dark Heart of Jason Voorhees".
Jason's heart was actually made of gelatin and filled with fruit cocktail from the crafts services table mixed with black dye. Actor Richard Gant was still disgusted and nearly threw up during the take.
There is a substantial amount of male nudity in this film as with female nudity, probably most notably in the "homoerotic shaving scene" as many fans have come to call it. The reason for this that director Adam Marcus viewed the previous "Friday the 13th" film as somewhat sexist, showing only or primarily female nudity, and thought it more acceptable to show male and female nudity in equal amounts.
Tobe Hooper was originally considered to direct.
This entry features the strongest clues as to the location of Crystal Lake. Namely, twice (once at the start, once when Steve Freeman sees the hitchhikers), a sign indicating that Crystal Lake is approximately 29 miles from Fairfield and 39 miles from Westport appears. Fairfield and Westport are both located in Connecticut. Previous films had indicated New Jersey or its environs; in part 3, a sign for Pick-It, the New Jersey state lottery, appears on the sign of a window at around 14 minutes into the film, while in part 1, Enos' truck has New Jersey on the side, and at about 11 minutes into part 1, the gates for a cemetery also has New Jersey on it.
The Assistant Coroner is played by Dean Lorey, one of the movie's screenwriters.
The patches on the shoulders of the Crystal Lake police uniforms state that Crystal Lake is in Cunningham County. This is a homage to Sean S. Cunningham, who is the producer of this movie, and was the producer & director of Friday the 13th.
John McTiernan was offered the chance to direct the movie but turned to down to work on Last Action Hero.
In extended interviews of Crystal Lake Memories documentary about Friday The 13th movies Noel Cunningham said that original rough cut of Jason Goes To Hell was over 130 minutes long and therefore it had to be heavily re-edited to be more faster paced and under 90 minutes long.
Agent Abernathy was named after Lewis Abernathy who helped Sean S. Cunningham make the underwater thriller DeepStar Six.
"Jason Goes to Hell" was released on VHS in both R-rated and unrated versions and on DVD with both the R-rated and unrated versions of the film on the same disc, the unrated version being three minutes longer. This is the first "Friday the 13th" film released Uncut in North America. Friday the 13th (1980) was released uncut in the U.S. on Deluxe Edition DVD in 2009.
Filmed from 20 July 1992 to 4 September 1992, but not released until 13 August 1993.
At the end, when Freddy's glove grabs Jason's mask, was meant to be an inside joke, referencing the fact that a screenplay putting Jason and Freddy against each other had been in the works since 1987, and had been intended to be Friday the 13th part VII. However, it took too long to come up with a good script for that film, so another film (Jason X (2001) ) was produced in the interval. Because New Line owned both properties, a joint project should have been easier to develop, but Freddy vs. Jason (2003) took several years (and sat untouched after several false starts) to come to fruition.
