Whenever I work on a part, I look at the world through the filter of the character and I pick things they might use through my observations of real life.

I don't have too much time to jam with the rest of Hollywood.

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.

Nowadays it seems more and more like the 'business' in 'show business' is underlined, and there are campaigns, and it's all part of getting people in to see the movies.

As filmmakers, we're constantly always looking for something to bring the audience deeper into the reality of the story we're telling.

It used to kind of upset me when I'd be working on a part in my hotel room, and I'd get an idea for a song and find myself on the guitar for an hour when I should be working on my lines. But I've discovered that when I start to shake up my creativity it wants to be expressed in all kinds of different ways. They all kind of inform each other.

During my early years, I thought I might be a musician. Like most kids, I didn't do what my parents wanted me to do. They were gung-ho that all their kids become actors. They loved showbiz so much. I am a product of nepotism, basically.
