Just because Fede Alvarez is directing a remake of Evil Dead doesn't mean that Sam Raimi is done with the franchise. At a press event for Oz the Great and Powerful, Raimi announced that he plans to return to his horror series with Evil Dead 4.
During a Meet the Filmmakers event in London, Raimi gave a rather surprising answer to a question about Evil Dead:
I would love to make Evil Dead 4. My brother and I plan to work on the script this summer.
Hopefully, Bruce Campbell is in this equation as well. It'll be interesting to see if Raimi has Campbell on board at this point—and what they have in store for an older Ash.
