It was dirty and hot, and you're on a horse, all day. It was physical work, but there wasn't one of us - cast or crew - who didn't have a smile on our face. Even when it got real hard and tempers would rise because things would get difficult and the day would get late, we all loved the job and loved doing it. When you finished that day of work, everyone was looking around and going, "Yeah, that was a good day, man."

I found a treehouse. I found this weird tree, out in a field, and someone had put a piece of a fence, way up in a tree. I just went up there and went to sleep for a few hours, in full cowboy regalia. And someone did take a photo. I have a photo of it, somewhere. It brought me back to when I was 12 years old, sitting in a treehouse and imagining that I was in a Western somewhere.

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.

I was really lucky that, through my 20s, I got to work with some amazing people, and I tried to sit back and watch and learn.

Kids will tease you for just about anything.

You spend all this time, as a child, coming up with these fantasy stories, and here I am, sleeping in a treehouse, in the middle of Canyon de Chelly, shooting a Western. That's a bit of a once-in-a-lifetime experience.

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.
