Michael Sheen apologized to his daughter for not being bald.

The actor’s 10-year-old daughter Lily, whose mother is actress Kate Beckinsale, was delighted when he landed the role of Aro in The Twilight Saga: New Moon, but the Frost/Nixon star was worried that his depiction wouldn’t match up with fans’ ideas of the role.

“I said, ‘What does he look like?’ She said, ‘He’s bald.’ I think she was mixing it up with Nosferatu, the old vampire, you know? But it shows that people, and this is the beauty of books for a start, that your imagination creates your own version of these characters. And so when a film comes along and you’re kind of going, ‘No, it looks like this,’ then that’s a very delicate thing to get right or to find a way to meet everyone’s imaginary requirements of the character. So I was very aware of that because of my own daughter. I said, ‘Sorry, I’m not bald. I’ve got long hair.’”

When working on his interpretation of Aro, Michael immersed himself in Stephenie Meyer‘s novels which the movies are based on.

“I would have loved to have talked to Stephenie loads about it, but I just kept rereading a few of the chapters in the book - especially the opening chapter where she describes Aro - just looking for anything that would help give me a clue. And then I was just left to my own devices.”
