It's amazing. It's just so far beyond what I expected when I was making it. Documentaries don't make a lot of money and don't have a lot of glamour.

I've often thought even ragtag gatherings of documentary filmmakers are more fun than gatherings of fiction filmmakers.

After college, I did a bunch of different jobs - taught English in Mexico, worked in public radio, worked for a web design company - but there was something about documentaries that really attracted me.

I was surprised to see how much the mainstream environmental movement hates the ELF.

I have a pretty positive view of environmental activism, but I didn't know much about the ELF. A lot of people make documentaries because they have something they want to say, but I make them because there's something I want to explore.

When I'm making documentaries, I think a lot about how fiction films play. I want them to have the pacing, the twists and the character development of fiction films.
