Actor Michael Sheen has been casted in “Twilight Saga: New Moon”. He will play the role of Aro, the leader of the vampire Italy group, the Volturi. Aro is an older character, not a tween, so they needed an older actor to fit the character. You would see Michael Sheen in such movies as, the “Underworld” trilogy, “Frost/Nixon”, “The Queen”, “Blood Diamond”, “The Four Feathers”, etc. No, he is no relation to Martin Sheen, Charlie Sheen and Emilio Estevez.
