Optimism is not inherently a superior way of viewing the world. Certainly doctors will say it might be better for one's physical health to be an optimist. But, morally speaking it may not be appropriate in certain circumstances.

When I want to show the kind of meanness people are capable of, to make it believable I find I have to tone it down. It's in real life that people are over the top.

Some people see me as dissecting my characters in some kind of heartless, coldblooded, analytical way, when in truth making these movies is a passionate, intensely emotional experience for me. I'm detached from the characters only to the degree that I have to be in order to write honestly about them.

If I grew up in a different background, I could see myself getting a gun and shooting an abortionist. That's my job, to imagine what could happen, what can make people go in different directions.

Casting is great fun, except for the business of it. I love the casting process. I love the editing process. I love working with the music. And even prep is very exciting. But once you get there and the clock is ticking, all it is is stress.

I love working with actors. If you cast the right person in the right part at the right time, they make you look like a better writer and director than you really are.

I think, in fact, there's a plus and a minus to knowing my prior work, Happiness and so forth. The plus is of course you can see how I play with the characters, the storylines, and the way things play off each other. And the minus is that it makes you a little bit more self-conscious, that you're not able to enter the movie as it exists and lives and breathes, because you're so busy making references, connections that you're not able to release yourself from and take the film on your own terms.
