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 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.

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 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.
