But anyone who's done a musical knows; whether you're dancing or not, physically it's the most difficult thing you can do.

My friends say, 'Man you're going to have kids sleeping on pillowcases with your face on it! You're going to be on toothbrushes and magnets and stuff.' I guess now that I'm a dad, I'm thrilled about that.

With age, you see people fail more. You see yourself fail more. How do you keep that fearlessness of a kid? You keep going. Luckily, I'm not afraid to make a fool of myself.

There is still boxing, but there's just no money in it anymore. If you went around the world and asked a bunch of people under 20 years old, to name a boxer, I bet they couldn't name one. They'd be able to name a UFC fighter though. When I was younger there was Mike Tyson and we watched everything. I'm not saying its gone, or its going to go, and it could easily be ignited by another fighter, but it's just that idea that UFC is more violent, that desire for more spectacle, has captured people's attention.

I've dreamt of being in a movie musical for a long time. For some reason I never even thought 'Les Mis' would be possible.

You have to eat before you train. Otherwise, that really intense training, after about 40 minutes you start to flag.

When lifting, I'm always with a trainer because the thing that makes a difference is that last 20% in your training, and he very scientifically looks after my food as well, because when I'm going for a 'shirt off' shot, everything changes the month before, and I'm timed down to the day.
