There are some audiences who are uncomfortable with the ambiguity, though. They want a film to chew their food for them, they want Hollywood endings that tie everything together in the end and answer all of the questions. They are usually people on one extreme of the political spectrum or other and they haven't been happy because the film is not polemical enough on their side. They aren't usually people who aren't interested in understanding points of view that they disagree with - they just want to attack their opponents - and I'm ok with them not liking the film.

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

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.

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.

Balancing the complex point of view in the edit room was mostly a matter of challenging ourselves to keep digging deeper.

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.
