Michael Sheen, best known for his work on such films as The Queen and Frost/Nixon, will now take on the role of "leader of the Volturi."In the new Twilight movie "New Moon" Sheen will play Aro. If you read the books like I have you know Aro is one nasty S.O.B. so I'm really looking forward to it! What do you think? Is it a great choice?
