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.

First of all, just to get Diner made would have been an achievement in that I got a chance to direct.

It's always hard to explain why an audience ultimately responds to a movie.

I think it's a promising time which will show a lot of diversification that we've seen in the past.

I play around with human things, human relationships and that, and allow that kind of talk to work in that way, on that level.

Rain Man certainly didn't test really well. If you look at it carefully, you have a disease autism they didn't understand back then, they didn't know in the test audience whether it's okay to laugh or not laugh, because it's a film that's done in a way where, "Well, maybe I'm not supposed to laugh." At the end of the film, Dustin Hoffman gets on the train and doesn't even acknowledge his brother. Not even a glance, nothing. That's why the studio said, "Can't you just have him look at Tom Cruise at the end of the film?"

Craig Nelson who is an actor and is in a show called Coach in the United States. We began to do some improvisational stuff and we used to get laughs and things.
