So I heard this a couple of days and didn't see a thread about it. Apparently after seeing the success of The Avengers, WB's thinks that they can do that with the Justice League. For those of you who don't know the Justice League, it's basically a superhero team from DC but the team includes Batman, Superman, Wonder Woman, Flash, Green Lantern, Aquaman, Martian Manhunter, and Cyborg. The film is slated for a 2015 release date and WB's wants to start shooting next year with no cast or director signed.
I don't know about this. The Avengers had all those solo movies leading up to it and all the Justice League will only have Man of Steel leading up. Guess we'll have to wait
