Moviehole, also a reliable source, claims The Hangover's Bradley Cooper is the front runner to play The Flash. Its unlikely WB would actually be speaking to anyone without having signed a director, but they may well have Cooper in mind. Funnily enough Cooper was also a contender for the role of Hal Jordan in Green Lantern, which of course went to Ryan Reynolds in Green Lantern, which of course went to Ryan Reynolds in the end.
Very early days but, I've heard Bradley Cooper, who of course was the runner-up for the role of Hal Jordan in DC's "Green Lantern", is the favourite to wiggle his way into the cherry tights. Warner Bros loves them some Cooper, and DC is very keen to have Cooper be 'part of the family', so don't be surprised to hear the "Hangover" star's name mentioned in relation to the role when the shortlist is inevitably leaked.I believe that WB got these castings a bit ass backwards and Reynolds would have better suite the part of The Flash and vice versa!
