Yep, that's right. Some light has finally been shed on George A.'s next movie: Survival of the Dead
The movie is supposed to be set after Land of the Dead. A group of people are searching for a way to survive and more importantly, find a cure and revive their undead family members. I guess, much like in Land of the Dead, the Zombies continue to evolve.
Not much more information is known about the movie. I'll keep you George A. fans updated though.
