Seeing David Mackenzie's work in "Starred Up," I thought that was a wonderful film.

I'm not locked into playing one guy.

You have to find your tone and work within that to make it as real so the audience can really engage in the story you're telling.

Words fall short sometimes.

Generally speaking I would say I enjoy the smaller films more because there's a less sense of pressure and often the material is more unusual. But in "Iron Man" it was kind of like both worlds colliding because there was a lot of improvisation, not that we improv-ed in the scenes but to discover the actual scenes themselves.

One of the things I want to do that's outside the realm of acting and the arts - although both have their place in this - is ending childhood hunger here in America.

I consider myself pretty lazy, but I look back and check out the stuff I've done, and I say, 'God, that's a lot of stuff for a lazy guy.' It's a paradox, I suppose, being both things.
