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.

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

I don't know that you can do an absurdist film and just have everybody embrace it in terms of filling out cards. I just don't think it happens. So you have to prepare an audience.

It's such a funny thing. Hollywood is terrible unless you happen to be a celebrity who's a Republican. So Ronald Reagan can be a Hollywood celebrity, and he's a Republican, and then he can become the president, and that's okay. Fred Thomson, well, that's okay. But the rest we need to demonize. There's no consistency.

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?"

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