Four months after we finished shooting, I'd been in New Orleans shooting another movie and my agent and I were having a bite to eat - actually in London - and he's sitting there and goes, 'Wow, I just can't believe how ripped you are.'

Marathon running, for me, was the most controlled test of mettle that I could ever think of. It's you against Darwin.

Like a lot of people, I've got a self-loathing streak that's alive and well. It acts as a de facto engine when I'm working, but it also has its extraordinary pitfalls, too.

We've all had that moment where the agent thought he hit hold. You hear it's like Hamburger Hill in the background.

As a kid, I think I wanted to be the on-set dresser for 'Charlie's Angels'. My goals weren't lofty. No. I just wanted to someday quit my paper round and that was about it.

Each time I take a role, I'm always nervous about it at the beginning and I'm always afraid what if that, what if this. Every time I take a role and I'm somewhat terrified at the beginning and I get into it and I start working, that's a big win for me. So, really it is stepping forward in the face of whatever fears that I've created for myself and going forward anyway and those are always big moments for me.

I remember that coming to America was scary for me because everything here is just bigger, better, shinier, you know?
