While the official Warner Bros. press release didn't specifically announce it, I've learned that Ben Affleck has signed a multi-picture deal to play Batman.
Described by a source close to Warner Bros. as "huge," Affleck has signed on for multiple movies portraying Batman and Bruce Wayne.
I've also learned that the as-of-yet untitled Batman/Superman movie will feature Lex Luthor, and that the role has been cast.
Previous rumors mentioned for Lex Luthor include Mark Strong and Bryan Cranston.
I haven't been able to verify whether or not Strong or Cranston has been awarded the role, or if it's someone else entirely.
The same source stated that Warner Bros. is building a lot leading up to the Justice League movie.
You can read the official Warner Bros. announcement regarding Ben Affleck as the new Batman, which also announced the movie has a July 17, 2015 release with production set to begin next year.
The film is also set to star Henry Cavill, Amy Adams, Laurence Fishburne and Diane Lane.
