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.

I've given no thought to moving to America at all.

I deliberately fly in and out of LA for as small a time as humanly possible.

I knew a bit but we don't study a lot of British history at school in Australia. We have our own 50-year period to concentrate on.

But it's healthy - whatever you can do to keep you fresh and awake. Acting's such a ridiculous job and sometimes you need to look at it like that to get a sort of degree of freshness.

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.

I think you need to be able to see a lot of negative in things in order to extract material, so there's probably something to that. A lot of the people I used to work with were very, very, very unfunny offstage, so that's a pretty common thing.
