We started training a month before the movie started and then by five months in, we were at our peak shape.

Doing a film with your friend is probably the best way to end that friendship but we worked together really well. We just have that thing. Chemistry is something that... I just think it is the last thing in Hollywood, the last magical thing they haven't computerised. There's nothing you can do about it - it's either there or it's not and it doesn't matter if you're friends or not. It was just a bonus that we were.

It's tough. It's very tricky to throw a morally flexible character onto the screen and have an audience empathize. It's always an exercise in restraint.

But if you do, then it's a high class problem to have. And if you do, you're the architect of that problem. There's no one else to blame but yourself. You've kept doing the same kinds of movies and that's what they want to see.

I don't necessarily need 400 pounds on my back in the squat rack, and then take a picture of myself and send it out to my Twitter followers, 'Part of the 400 pound club today.'

Every time I hangout with Sandra Bullock I think I want to be her. I want to be married to Jesse James.

Any kind of crisis can be good. It wakes you up.
