This is some pretty interesting news. I still have yet to see Twilight but the sequel 'New Moon' is really shaping up to be an interesting cast. Michael Sheen is the most recent addition to the 'New Moon' cast and he will play the character Aro who is a member of the Volturi, the leader actually, and he can read the thoughts of people who he has physically touched. The director of the film Chis Weitz says:
Michael’s role is so important because he’s the head of all vampires. Aro is, on the surface, a very gracious and friendly vampire, but beneath that he is a tremendous threat.
If your still not sure who Micheal Sheen is he played Lucian in the 'Underworld' series and he also played the lead role in Ron Howards 'Nixon', which he was fantastic in. So it looks like he will be going back into the fantasy world of Vampires and Werewolves but on a different team this time around. I like this guy as an actor so does that mean I have to finally start watching these films? The director of the film Chis Weitz says:
