In a movie, a book, or a play, a character doesn't live in a vacuum. She is subject to pressures from the world outside of her, just like we are in life. These pressures and circumstances shape character. Who your parents are determines your genetic make up: your skin color, your sex, your height, weight. Where you are raised does affect your worldview either positively or negatively, your accent. Your economic class affects where you go to school, what you eat, where you sleep.

Anyone has outside influences. They are the results of the cosmic roll of the dice: this person is born Aragon the Ranger, this person is born a prisoner in North Korea, this person is born Carlos the Dwarf. Some of these things are out of our control, but that doesn't mean that they can't be changed. A character, just like a person in real life, is a summation of her actions and feelings. Our actions and emotions are not performed against nothing, they do not arise from dust, we are in constant friction, and/or flow with our surroundings.

When I went to film school about three years ago, the first two years you're required to make a series of short films. I started making films based on short poems.

I put out a lot of different kinds of material, and maybe people read that as egotistical. Or maybe, since a lot of it does involve some aspect of me, they find it self-aggrandizing. But there’s a long tradition of artists using themselves. Look, I know I’m not perfect. And, who knows, maybe a part of it has to do with self-obsession. But it’s also about using this weird thing that is a public persona as raw material for creative projects.

It's basically the best job in the world. If you're fortunate enough - and I consider myself fortunate - you get to work with your friends and you get to work on projects that interest you.
