The next Batman flick, which is tentatively titled Gotham, will have Murphy playing the role of The Riddler while LaBeouf will play the caped crusader's sidekick Robin.

Actress Rachel Weisz [Images] of The Mummy [Images] fame will reportedly play Catwoman as Christian Bale [Images] returns as Bruce Wayne along with Michael Caine to play his assistant Alfred, The Sun newspaper reported.

After the success of The Dark Knight [Images], director Christopher Nolan has been roped in again for the next movie which is slated for a 2010 release.

"Chris wasn't sure if he wanted to do another movie but as soon as he decided to, he got the wheels in motion. Eddie's a fantastic addition. Everyone's excited to see what he does as the Riddler," a source told the newspaper.
