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.

In a weird way, I live vicariously through the characters I play as an actor.

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.

It was dangerous stuff. We were running on top of moving trains. We got to do amazing things. I like doing stuff like that. I enjoy it. But believe me, there were things that were so dangerous that I wasn't touching them.

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.

Not every conspiracy is a theory.

Kids will tease you for just about anything.
