Film is such a director's medium; you're really in their hands in terms of the real storytelling. As an actor, you can give a performance moment to moment and some of your takes will be used and some of them won't. I think there are great films you can make with bad performances, and vice versa. There are all combinations of those things. It's really down to the director what happens, I think, so that's why it's really good to work with very talented, bold directors.

I think London's sexy because it's so full of eccentrics.

You never know how things will turn out. And you can't really say it turned out wrong. Whatever happens, happens. The important thing is that you followed your gut.

Eccentricity is what's sexy in people.

It's also that comedians don't have the kind of narcissism that actors have. They're writers who perform their own material. It's more interesting. And they're sexy because they risk more. Stand-up comedians risk more than anyone.

I don't know anything about science.

I just think that things get easier as you get older and wiser and more experienced. You get more confident about who you are as you get older. I find that really comforting.
