I got involved with an acting school and studied for a couple years. They used to have improv exercises that you would work on and you would do improvs.

The interesting thing about movies, it's not always - y'know, you have to have structure etc and all those things, but an audience responds, in many ways, we walk away and certain things stay in our heads that are memorable.

You don't always have to have the ending, but you want to have a satisfactory conclusion.

There's no downside to having too much experience.

I don't know that you can do it as a satire. I mean, the business is crazy enough as it is. It's like doing Wag The Dog - we took a thing that was almost completely absurd on one level, and then ultimately those things came about.

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.

They're intimidating the networks and levying these fines, so the networks are not sure of what they can or can't do.
