MTV: You must have a whole new fanbase now.Sheen: I'm very big with the under-12s. They're very big fans of "Frost/Nixon."MTV: Tell us about your character in "New Moon."Sheen: I play Aro. For people who aren't fans of the books, I play one of the Volturi — somebody described it as being like the royal family of vampires, which I guess is a good description. He's very calming on the surface, very gentle and soft on the surface. But beneath, he is a psychopathic killer. ... He's a great character, and I had a great time doing it.MTV: When will we see Aro next?Sheen: Well, he doesn't appear in "Eclipse." He appears again in "Breaking Dawn."MTV: Have they told you to set aside some time for that one?Sheen: Who knows? Nothing has been spoken about yet.MTV: We can also see some teases of a dark Dakota Fanning in the "New Moon" trailer. How is she in the film?Sheen: She's fantastic. She's scary as hell, but she looks so sweet. She's got a great character there. People are really going to love her.
