Louis Theroux

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 didn't think, 'I'd really like to work in TV; maybe I could carve out a niche where I talk to people who are somehow involved in marginal or difficult lifestyles... ' It was something I gravitated to very naturally as a subject area, almost instinctively, and somehow turned into a TV career without meaning to.

By irreducibly complex I mean a single system composed of several well-matched, interacting parts that contribute to the basic function, wherein the removal of any one of the parts causes the system to effectively cease functioning.
