Affleck take over as Batman), a new report from LatinoReview (via ComicBookMovie) has Warner Bros. trying to secure the return of Christian Bale as Bruce Wayne, and bring back Christopher Nolan as a producer (Zach Synder too, so this would clearly depend on the success of Man of Steel). Bale has previously said he'd consider returning provided Nolan was on board, while Nolan has said he wasn't interested. However, Warner would probably be willing to move Heaven and Earth to get this done, as such a move would allow the film to overcome the hurdles that other options would face. Basically, this would let the Nolan films serve as setup for the Justice League, instead of requiring audiences forget everything they've seen in those films. Unfortunately, even if rumor is true, it doesn't mean Warner is going to be able to pull off the deals, as they'd likely be be looking for a long-term commitment from both Bale and Nolan. There's a spoiler for the end of The Dark Knight Rises below. You've been warned.
So yeah. Spoiler.
At the end of The Dark Knight Rises, Bruce Wayne retires as Batman, leaving the keys to the Batcave to Robin John Blake (Joseph Gordon-Levitt), and goes galavanting around the globe with Selina Kyle (Anne Hathaway). Even keeping strict continuity, this wouldn't be a problem for Justice League, as the team would only form in the face a world-threatening entity that would easily be enough to force Bruce Wayne out of retirement. Anyway, if this works out, it will be on-par with Marvel hiring Joss Whedon as the most awesome piece of Comic Book movie news ever.
