It really depends on the director. I think quite often, it's not what you expect. The most serious film can be the most fun. The one that's supposed to be fun can be the most serious. I don't think there are any hard-and-fast rules. I just think it really depends on your director and what the general vibe is.

The movies people don't talk about or remember after six months' time don't really matter.

I was a fan of the television show as a kid but I wouldn't say that I've followed all the movies or anything like that. But I was a television junkie as a kid.

It's got to be a challenge but at the same time you have to feel as though you can play them - it's really dangerous to want to be a part of something just because you think it's going to be great. I've been sent plenty of scripts where I've known that it's going to be a great film and a successful one, but I just couldn't convince myself that I was the right person for the part. So, I think you have to be careful with that.

The thing I love about working with first-time directors is that it's always quite shocking how little difference there is between them and directors who've been directing all their lives.

I'm realistic about it. It's been quite some years since I've worked full-time in that area, so I no longer have any material that bears any relevance to my life or the audience. I'd need to take probably a year off, which I wouldn't be prepared to do, so it's a romantic ideal.

I wanted to be a mechanic. When I was 14 I wanted to quit school and go work on my car. But my dad said Son, you shouldn't do that. You should stay in school until your education is finished, and when you're done, don't make your hobby your job.
