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 certain movies work and that is part of the magic of it all. We can't truly define why something succeeds.

I think when Sarah Palin opened her mouth and started talking, the more she talked, the less appealing she became.

Different reactions while film test screening doesn't mean even the audience thinks ambiguity is a bad thing. But if you're asking them right away to start checking things off, they don't know what to do. I think at their best, it applies to when the audience knows what it is. Then, when they say, "Oh, well, I thought it was too boring in blah-blah-blah part," then you better pay attention to it. It's like going for the hamburger. Better be the good hamburger I went for.

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

Creative differences are legendary in this movie business, so we're really not exploring the creative-difference aspect as opposed to the money aspect, or the fact that something can come up in a movie and literally put the whole movie on the line, and this is where producers have to earn their keep.

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.
