Note: while fans may have wanted Michael Myers from “Halloween” involved in a monstrous battle royale, including him in a script was never anything more than conjecture.
Unlike a “Hellraiser” crossover, a treatment for “Freddy vs. Jason vs. Ash” was actually written in full. According to a different article in Bloody Disgusting, New Line Cinema executive Jeff Katz wrote a story wherein Ash (Bruce Campbell), usually wrapped up in the slapstick violence of nondescript demons called Deadites, was to fight both Freddy Krueger and Jason Voorhees, killing off Freddy once and for all. Resourceful internet hunters can find the treatment online. Ash, to remind readers, was a comedically a-hole-ish antihero who would most certainly live through a monster fight, wielding a chainsaw affixed to the stump where his right hand used to be. Ash wouldn’t “win,” however, as he is incredibly unlucky; Katz wondered in his treatment if Ash should be unwittingly sucked into an alternate dimension at the end of “FvJvA.”
The connection between “Evil Dead” and “Friday the 13th” or “A Nightmare on Elm Street” seems tentative, until fans of “Jason Goes to Hell” recall that the Necronomicon, the book of unspeakable evil from Raimi’s films, made a cute Easter egg-style cameo in the 1993 film. Katz took that cameo quite literally. Horror fans would do well to read Katz’s treatment, as it’s quite a hoot. The film itself was never actually put into production, however, and eventually was transformed into a six-issue comic book series, published in 2007 and 2008. The comics merely extrapolate the original idea, expanding them a little bit. The next year, “Nightmare Warriors” was also published. That one was wholly original.
Even without the unmade sequels, though, “Freddy vs. Jason” is a fun, fan-service film for the ages.
