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 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.

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.

Producer Ed Pressman had a book about Diane Arbus - it's the only biography that exists - and there had been many Diane Arbus scripts. Many. I don't even know how many over the years. And it's sort of a cursed project, for lots of reasons. There's probably some pile somewhere of all these weird attempts, all these portraitures that can't get made.

Focus group was helpful in the way it always is when you make movies, especially with anything funny. You can find the right edit or the right beat. In terms of cutting and rhythm, I think it's essential to screen your movie before you lock picture.

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.
