There have been times when I've felt inappropriately emotional. I remember making 'The Most Hated Family in America' about the Westboro Baptist Church, and being on the way to a funeral of a U.S. soldier with the Phelps family; they were going to picket the funeral.

I really do try not to emote. I don't like seeing it on documentaries - it seems a bit unprofessional. I also need to be human being and be a kind of sympathetic presence for the contributors I'm with, so there' a line you have to walk.

I never want to feel more than the viewers. I'm not trying to be an automaton. It's like when you see people laughing on camera, and you don't find it funny as a viewer - it's an offputting experience.
