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.

Over the past decade... while many businesses have pursued what I call 'business as usual,' I have been part of a different, smaller business movement, one that tried to put idealism back on the agenda.

The thing about dancing - what it taught me all those years - is it gives you an amazing sense of discipline in forcing yourself to do things that you know are good for you but you don't really want to do.

Sometimes you see films, not just science fiction films, where you get the sense that if the camera were to pan just to the left or the right, all of a sudden you'd be seeing light stands and crew standing around. But with 'Blade Runner,' the beauty of it is that it felt like a real, breathing city.
