Michael Sheen, that is.

The man who played Tony Blair, Brian Clough and David Frost has experience with vampires and werewolves - since he's played ferocious furry type Lucian in the three Underworld movie.

This time, however, he's switching sides to play Aro, leader of the Volturi in New Moon.

He's not worried about criticism of the series - "I take it seriously, but it's up to other people how they respond to it. I have no control over that.

"I just want to do as good a job as I possibly can for Stephenie Meyer, who wrote the stories, Chris Weitz, who directed the film, and for my daughter, who's the person who got me into it in the first place.

"So if people don't respond to it, that's up to them, but I don't think anyone's going to be too worried about that. I think there's quite enough people who are into it."
