You want to work with good people. When you're working with good people, it frees you up. There's nothing worse, as an actor, to show up and then feel like you have to protect yourself somehow because you don't feel like you're in good hands.

Marvel is very secretive, so there was no script. About six months before production, they gave me some pages and it was from a cop movie. And then, six months later, I got a phone call saying, "Do you want to come do this?" [iron Man]

As we were negotiating, I didn't have a script. Once the deal is closed, they let you read the script. So, I got the script and was reading it like, "Oh, please be good!," because I'd already signed on the dotted line. And I read it and just went, "Okay, I'm going to be okay. Thank god!" It was a really funny, moving story.

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.

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.

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.

I got beat up by the comic-book kids when I was younger! They were cooler than me. Talk about levels of geekdom, I was a couple rungs below the kids who read comic books. Yeah. Not so cool, man.
