Unfortunately, one of the biggest reasons that "Freddy vs. Jason" hasn't happened to this point is that actor Robert Englund — the only man to portray Freddy Krueger until 2010 and an integral part of the franchise's success — is no longer interested in playing the character. "I'm too old to do another Freddy now," he told Entertainment Weekly in 2017. "If I do a fight scene now, it's got to be real minimal because I can't snap my head for eight different takes and different angles." 

Englund doubled down on this in 2023, telling Variety, ""I'm too old and thick to play Freddy now. I just can't do fight scenes for more than one take anymore. I've got a bad neck and bad back and arthritis in my right wrist. So I have to hang it up, but I would love to cameo." However, the horror actor did suggest that Kevin Bacon might make for a good Freddy, saying the way he moves might be perfect for the part.

With all that said, however, if the screen treatment that had been leaked by Bloody Disgusting had ever been made, we know it would have starred Englund and Bruce Campbell, as well as Monica Keena and Jason Ritter, returning as survivors Lori and Will. Keena even addressed the possibility recently while talking with the podcast Happy Horror Time, revealing that both she and Ritter had options for a sequel in their contract for the first film. 

Of course, it's also likely that Ken Kirzinger would have reprised his role as Jason Voorhees too, and he may even still be up for a return if somehow a "Freddy vs. Jason" follow-up could ever be made. He made this clear during an appearance at a panel during the Spookala Horror Convention in 2022. "If they asked me to do that, I'd be very happy to come back," he told a moderator when asked about a possible sequel.
