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.

A lot of time mistakes are very interesting - you look for the behaviour that's not the one you expect.

I don't know what Bruce Willis has done in real life. We know actors have certainly had tirades - that's for sure. I never had troubles with him, but the big issue is really less about what Bruce is, as opposed to - this behavior has taken place, and sometimes it came out at something that had credibility, as opposed to, "No, I want to be fat and have a beard." Other people say, "I don't give a damn about the credibility. I paid $20 million. I want to see a movie star."

I'm emotionally invested in every movie that I do, period, because you've got to make that commitment. You're spending a year, 18 months of your life doing it. I'm invested in all those kinds of pieces. Most of the films I've had in my career have never tested well. I got lucky that sometimes I got supported by studios - or, at least if not supported, tolerated.

Producers - we always think, "Well, producers are very powerful," but producers don't really have the power. It's the appearance they might, but they don't. Even the actors don't. Even the studio heads don't, because they're beholden to this corporation and what the corporation wants. So no one really has the power, and everybody's trying to get through the day, and everybody's nervous and desperate.

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

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?"
