I'm from a nice, suburban, middle-class family, but my tattoos remind me where I've been.

I'm not a big guy anyway. I'm only, what, 150 pounds? I was 190 for 'Batman,' 179 for 'Warrior.' Films make you look big.

I'm here to challenge myself and to see whether I can shape-shift in an environment that's actually quite daunting, but which I think would be nice to shine a light into. The destination of any interesting drama is that you shine a light into a place that not many people know about.

Then there's your diet. You cut out sugars, fat, soy sauces... anything that's nice. Tea and coffee is replaced by boiling water with lemon. It's amazing how quickly you get into it. There's also herbal tea and a lot of water, obviously... about two litres a day.

The lack of carbohydrates can make you a little crazy.

Love is doing something you don't want to do for someone you don't particularly like at that moment.

I play Xbox. I have a little boy to look after. I have dogs. You know, I have things to do. I would love to be able to sit down and watch something like a movie. I watch my own movies because I have to.
