Looks like Leonardo DiCaprio's going to venture back to the period setting that worked so well for him in Shutter Island, though this time, he'll going to slip into something a little more comfortable. Deadline says the actor will be playing J. Edgar Hoover in Clint Eastwood's upcoming biopic (which the director discussed with Movieline recently). We can only assume that there were no more open roles in Scorsese's next picture for him. [Deadline]
