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.

Mysteries include so many things: the noir novel, espionage novel, private eye novels, thrillers, police procedurals. But the pure detective story is where there's a detective and a criminal who's committed a murder and leaves clues for the detective and the careful reader to find.

Every time I see documentaries or infomercials about little kids with cancer, I just freak out. It affects me on the highest emotional level... Anytime I think about it, it makes me sadder than anything I can think of.
