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.

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.

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.

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.

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.

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.

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.
