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.

Little projects - not feature - film projects - you know, theater things, writing things, and jobs like doing rewriting for money, stuff like that. I don't recommend it. It's not a schedule that I'd want, although it was really good for me in a lot of ways. I became a better writer.

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.

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.

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.

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 just thought that was so interesting, that people that deal with bodies on a much more corporeal level, like the attendants, had a whole different set of criteria than doctors, and that they had this secret knowledge of something. I thought it was strange and interesting, so I took it to my script.
