Starting writing is stressful and scary and hard, but also, it's just like going to the gym. You're just stiff and weird, and you can't do it as well.

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.

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 had the experience of having my grandmother in a nursing home at the end of her life, and had dementia set in with my father. He was in a nursing home with dementia at the end of his life, but it happened for me personally 10 years ago. My father was much older than my mother, so I experienced it as a pretty young person. People's parents die at various ages, but my father died of mortality. He died of being an old person. Illness and stuff happened, but essentially, he was old and he was going to die.

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.

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.
