I'm not quite sure who posted this rumor first. Both Latinoreview.com and Collider.com posted stories today that George Miller would be directing Warner Brothers and DC Comics Justice League of America movie.
Of course, this is purely speculative. The information is said to come from a "very reliable source". And Miller could jump off the deck at any moment. I guess we'll just have to wait and watch for this to be confirmed.
The elusive source also stated that Superman, Batman, The Flash, Wonder Woman and the Green Lantern were all slated to appear in the film. And that we are more likely to see Brandon Routh starring in this before we see him in Superman: The Man of Steel, which is slated for a summer 2010 release.
The rumor also has one of the comic book characters dying. While the source knows which character that is, they aren't saying.
