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 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.

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.

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

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 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.
