There was a time when I said, "I'm going to go do a television thing," after doing all these theatrical films, and heard, "Television? Why are you going to go back to television?" It's an interesting place.

If you test Iron Man and that audience doesn't respond well, you can be damn sure that there is something wrong with the movie that you have to address. Because they're expecting a certain amount of action, right? They want a hero. There are certain things that have to be compatible with the way the audience is thinking about it. If you take some other film, like No Country for Old Men, you can end up with all kinds of crazy reactions.

A lot of people have done things over the years and made fun of people in one way or another. When I was a kid, Vaughn Meader used to do John F. Kennedy. I don't know if that makes John F. Kennedy less credible. He would do the voice, he'd have some silly situations or whatever. I don't know if it made him less presidential because of it.

I got a chance to work with Mel Brooks on two of his films: Silent Movie and High Anxiety.

All I try to do is create an atmosphere that seems comfortable enough, that it removes tension and everyone feels free. If they feel free then behaviour happens, small moments happen and that's what ultimately works the best for me.

I do know when you look at some ballplayer and all of a sudden he is the size of a truck something is wrong.
