Obviously, once you're finished, you're like, "Okay, I have to make this a movie now, and I need people - bodies to play these parts, and actors to bring this thing beyond a script." But when I was writing it, I wasn't thinking of actors; I was really thinking about creating three-dimensional characters.

Writing is so... I don't know, it's such a practice, and I feel very unpracticed in it, because I'm not doing it every day. And I really need to do it every day. In other words, you spend all this time writing a movie, and then you stop, and then you're shooting the movie, and then you're cutting, and a year and a half goes by, because in the editing room, you're not writing.

I remember in film school, when we made shorts, you'd sit there and screen them with your peers, which has its own flavor, because everybody's so competitive and evil, and it's a really nasty environment.

In terms of my peer group, nobody's parents were dying of old age. There was no dialogue to have among friends. I had that experience, and then 10 years later, I started thinking about writing about it. It's obviously an indelible thing when that happens, and I wasn't looking for material at the time or anything; it just started becoming relevant to me.

I spent a lot of time on Diane Arbus film, not only writing it, but running around talking through various production issues. All this crud, and then it didn't happen. There's a lot of time-wasting stuff that happens in life with movies.

Ideally, I'd prefer never having to be in a test-screening environment. Some famous director said "The group is smart, the individuals are stupid," about the experience of a test screening.

That's what all these studios do: They recruit people who've seen certain films. It's this weird, fake science-y thing the studios call a "tool." That's a very scary process, because it can be used in odd ways. But then there's focus groups and stuff like that. I was so nauseous and terrified, and then you get the cards: very good, good, recommend.
