When I was a kid, I wanted to be serious, like Daniel Day-Lewis. No one really dreams of being a comic actor, do they? Now I realise how stupid that is - and it's because comic acting isn't taken seriously enough. It's a discipline. You know instantly - either you're funny and getting the laughs, or you're not.

I don't really know what it is about vampires that makes them such a powerful symbol, metaphor, whatever in people's consciousness. But I do know they're tremendously powerful. I mean, there's a vampire on 'Sesame Street.' And Count Chocula. I don't know why it's so powerful.
