"Sons Of Anarchy" Star Playing The Flash?

Charlie Hunnam, star of TV's "Sons Of Anarchy" is said to be playing the role of The Flash in Warners planned "Justice League" film in 2015. Online sites are saying that his likeness is being used in concept art for the high speed superhero. We yet have any confirmation from Warner or Hunnam, but the sites are saying that the info is from trusty insiders over at Warner.
Personally I think he'd be pretty cool looking as The Flash. I've never seen "Sons Of Anarchy", but I've heard it's amazing and that he's great in it. Hunnam is next seen in Guillermo Del Toro's sci-fi film "Pacific Rim" with Idris Elba.
