I went through about 40 different hats until we found one that fit. It had to fit me and fit the character, more importantly, and whatever that thing was that we were trying to create with him.

The physicality was important to me. Because the film has Shane Black's dialogue, and [Robert] Downey's delivery, and you look at [Jon] Favreau, Don Cheadle and Gwyneth [Paltrow], it is this heightened level with a comedic aspect to it. Everything is grounded in reality, but it plays a little heightened.

We're just one cog in this giant machine. You show up and look at all the other cogs like, "Wow, everyone is the best at what they do." You're in really good hands. And that frees you up to play and feel safe, and you can take chances, creatively. You can take risks. I want to show up to work and take risks. I don't ever want to play it safe.

The older I get, the more vegetables I eat. I can't stress that more. Eating healthy really affects my work. You not only need to be physically prepared, but mentally and spiritually.

My experience as a young actor on network television was that I couldn't make it work. I was drowning as an actor.

These stunt guys are good at what they do and they're professional. A smart actor will step back and say, "I'm going to let the professionals do this." Hats off to those guys, man. When you see the credits scroll, look at all those stunt guys and remember all those names 'cause they earned their money on this.

I don't know why I just remembered this, and I haven't told anybody this, but we were shooting in Canyon de Chelly and we were so far up the canyon. Once we were up there, we were up there. There was no going back to your trailers.
