You have to find the tone of the piece and modulate that. There are ways to indicate that - I try to incorporate the biggest range I can within the story, going from humorous to serious without it being jarring. That's the hardest part, to keep that balance. It requires being constantly aware of where you are in the story. You can't really do that in a movie: You can't slightly modulate the tone by the way the character's eyeballs look in one certain scene.

I'm always looking for things I imagine must exist, but don't - this is usually the impetus to create that thing myself.

Something I always wanted to do, to capture that later half of the '70s. It's like the early half of the '70s is still the '60s, in that there's still kind of a playfulness and inventiveness in terms of design and the things that were going on in the culture. The second half, it got much more commodified. It's possibly the ugliest era of architecture and clothes and design in the entire 20th century, from 1975 to '81 or '82.

I try to only work on the screenplays for a few hours a day when I'm in my most voluble mood, just sort of writing whatever comes into my head. It's a very freeing thing.

I see a lot of possibilities in the age of my characters - between 18 and 21. You have a window of opportunity when you leave your childhood behind and have this chance to become what you always wanted to be. For me, that was a time when I could have gone many different ways. I was in flux and deciding what kind of person I would become. There's something interesting about the vision of what that will be and the reality of making that happen, and how you really are what you are. Unless you're "in character," it's impossible to get around that.

I'm a fan of parchment and wood pulp.

I think that's what we're all most terrified about: that we'll just die and disappear and we'll leave no trace.
