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 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.

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

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.

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 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.
