Warner Bros. is moving aggressively ahead with the big screen adaptation of DC Comics' Justice League of America, with George Miller (Happy Feet) on board to direct, reports Variety.
The project, which is in the initial phases of casting, is a pre-strike priority for the studio, which needs a superhero tentpole in 2009.
Still, making all the pieces fit has been complicated by overlapping superhero projects in the pipeline, since "Justice League" features a pantheon of superheroes, including Superman and Batman.
Batman and Superman are active properties for the studio, though the next installment in the Superman franchise has taken a backseat to "Justice League" in part because Warners is so keen on the "Justice League" script by Kieran and Michele Mulroney.
"Justice League" will likely feature the characters of Superman, Batman, Wonder Woman, the Flash and Aquaman.
The project is so complicated -- and casting dependent -- that even those deeply involved in the project are holding their breath until production begins.
"They're working very hard to get it to happen," said one party close to the project. "But there are so many characters it's complicated."
This would be a major undertaking bringing the Justice League Movie to the big screen.
