Director Fede Alvarez revealed at WonderCon on Sunday that both the classic "Evil Dead" and the upcoming remake/reboot will hopefully crossover in the future.
Alvarez says that they hope to make a sequel to the remake opening this week, while Sam Raimi and original series star Bruce Campbell will move forward with "Army of Darkness 2".
Then, assuming everything comes together, those in the new franchise who've made it through can combine with Campbell's Ash for a final film which would essentially be the seventh in the franchise.
As of now, Sam Raimi and his brother Ivan are busy at work on the screenplay for "Army of Darkness 2".
