Bradley Cooper sought for 'The Flash'?

Rumours that Bradley Cooper is in line for the title role in DC and Warner Bros' The Flash have emerged.

According to Moviehole, the Hangover star is the frontrunner to play the Scarlet Speedster in the proposed comic book adaptation.

Green Lantern screenwriters Marc Guggenheim, Michael Green and Greg Berlanti are working on a script for the project. Their latest draft is expected to be completed between Thanksgiving and Christmas 2010.

Previous reports have also linked Berlanti with the director's chair, although an "inside source" has since told Deadline that the scribe is unlikely to helm the venture.

"He won't want to direct it because he kinda wants to do something in between size-wise first before attempting something that large," said the insider. "If Warner Bros does like the script and wants him to direct it... But that's a lot of ifs. And all of it is moot if they don't dig the script. Green Lantern wasn't real until the studio liked the draft."

The Flash is tentatively scheduled to arrive in theatres in 2013.
