"I would love to make Evil Dead 4. My brother and I plan to work on the script this summer."
The brother he is likely referring to is Ivan Raimi, who co-wrote the screenplays for Army Of Darkness, Darkman, and Drag Me to Hell with Sam Raimi. His other brother, Ted Raimi is better known as an actor, who has a small role in Oz: The Great and Powerful and many of Sam Raimi's other films.
It isn't immediately clear if Bruce Campbell will return as Ash in Evil Dead 4, the iconic character he portrayed in Sam Raimi's trilogy The Evil Dead, Evil Dead 2: Dead by Dawn, and Army Of Darkness, although it seems likely. He helped produce the Evil Dead remake along with Sam Raimi.
