Although my dad's a writer, we grew up in a telly-watching household. I never found him disparaging about television.

In the past, I've tried to show the human side of people involved in stigmatised or misunderstood lifestyles. I've tried to resist easy judgments and not pander to prejudices.

The trouble is, I just don't know if I'm too human or not human enough.

I don't feel that as human beings we have an obligation to dislike someone based on their beliefs, and it's OK to have a human reaction to someone even if you feel what they do is hideous and objectionable. You can still enjoy their company and find them interesting to be around.

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.

There's obviously a lot of controversy around the issue of hunting as there is around gambling, and I like these stories where there is a moral dimension, stories that force you to think about your prejudices about a subject and explore the extent to which they are justified.

When it was time to meet a chimpanzee, I got very, very anxious because they have the strength of ten men, so I hear.

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.

I think he could win, absolutely. I think he could win because there's Trump supporters out there who aren't even revealing themselves as such. For me, that's a scary prospect because I think he'd be a disastrous president.
