I love to just listen and watch. I could happily watch a security camera at a store. Often during a day I'll see a guy selling pretzels or an argument that somebody's having on a stoop and I'll think, "Oh I wish I had my camera, I wish I could capture this moment." There's something about people being people and interacting that can be so beautiful when it's framed by a camera. That desire to capture people as they are, and the stubbornness to keep going when they don't necessarily want you to capture them being who they are, are key.

I think this is one of those issues where the deeper you dig, the murkier it gets - and everyone who has spent a lot of time thinking about these issues.

I think if the extremists were happy with my films, I'd start to worry.

It was our goal to dig into the characters and really try to find out why they think the things they think and why they do the things they do - and we got some amazingly candid and revealing interviews - but it's not my job to offer summary judgment on those interpretations.

I took a leave of absence from the internet company where I was working and bought a camera and a copy of Final Cut Pro editing software and made my first feature film, "Street Fight." It followed a crazy, racially charged mayoral election in Newark, NJ in which a young guy named Cory Booker was taking on the political machine of that city. It went on to be nominated for an Oscar and Emmy and was a real example of DIY film-making.

Most of this film, however, is about interpretation - are these people terrorists or freedom fighters? Are they good or bad? Is cutting timber good or bad? And I don't feel like the answers to those questions are simple, so we don't try to answer them for the audience. I wanted to elicit the strongest - and most heartfelt - arguments from the characters in the film and let those arguments bang up against the strongest arguments of their opponents.

I have a point of view on the issues, but it's a complex point of view that really can't be summed up in a sentence or two. I'm not being intentionally vague or mushy, it's just that - in my mind - the real answer is complicated.
