Michael Sheen apologised 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.

He explained to About.com: "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.

He added: "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."
