I loved watching documentaries and had wanted to try making one for years - I'd just put it off as other opportunities arose. But I felt like time was running out for me if I wanted to do it.

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've always been curious in why different people believe the things they do and do the things they do - in the different ways that people live.

I have wondered if I might be placed on a watch list of some sort by the government, though. I know that the documentary filmmaker Laura Poitras, who is a friend and who has made documentaries about controversial Middle Eastern terrorists has had trouble at customs when she travels internationally - but nothing like that has happened to me.

I think that any time you are making a film you have to realize that the people you are talking with might be giving you misinformation. Sometimes it is factually incorrect and for that, it's important to me to check it out and not let things find their way into the film without being challenged, either by me, or by another character, or by evidence that you might see on screen.

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.
