People, when they get out of a long stretch of prison, are completely mal-adapted to society. Comfort for them is when there is a threat.

When you can't fix all your problems with your fists and the problems aren't solely physical, and you've got to deal with the emotional complexities of life and people, it's a really interesting development.

I don't mind violence, but it's quite an interesting thing for people to deal with. I don't know many people that like fighting. I certainly don't, myself. But it's always interesting to work on a shows where there's so much violence, as a part of the world.

I did martial arts and karate for eight years when I was growing up.

I had a job when I was 15 working at a supermarket, and I knocked over a stack of plastic coffee cups. In my anger, I threw one at a concrete wall, and it rebounded back into my head and cut my head open. Stupidest way to get a scar, but it's one that I have.

I think the film and TV industry - the acting world - has a tendency to attract a lot of people for the wrong reasons; reasons that are less than artistic. It has a tendency to be pretty superficial, and pretty shallow and fake. I think what New Zealanders and Australians - and the English, I guess - have to offer is that we don't carry a lot of that baggage. We come over and we're pretty grounded. But on the flip side of that, you end up in a very unfamiliar environment being treated in a way that's a little bit surreal.

The American accent is a little bit tricky. We grew up with American TV shows, so we've had a lot of exposure to it and that helps, but there's little nuances and little details. Sometimes there'll be just a phrase or couple words that are really difficult to get your mouth around. At the end of every season we go over and revoice anything that has sound issues, including my kiwi accent coming out.
