Following in the wake of such films as "Jodorowsky's Dune" and "The Death of Superman Lives: What Happened?," a new feature-length documentary is in the works about "Justice League Mortal," the DC Comics adaptation that "Mad Max: Fury Road" helmer George Miller was slated to direct before the project fell apart back in 2008. Short film director Ryan Unicomb is teaming with producers Aaron Cater and Steven Caldwell and Sydney-based writer/author Maria Lewis to develop the documentary which will reportedly be an unbiased account of the superhero ensemble project's gestation, development and ultimate disintegration. Currently going by the working title of "Miller's Justice League Mortal," Unicomb is said to already have private investors lined up though he may augment that however with a crowd-funding campaign.
