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.
Empires will come and go. The Soviet Union collapses; China can become a superpower, but 'Blue Peter' stays the same.
When you don't have access to a subject, and all you have is ex-members and critics, there is this gravitational pull toward telling a certain version of events. Scientology would say this, and they have a point, that it's like doing a portrait of a marriage in which you're only hearing from the ex-wife and not the ex-husband.
Big game hunters and the hunting industry in South Africa know a lot of people regard what they do as terrible, and the media have tended not to do them any favours. So it was an uphill struggle to win trust from the people and to get into the world.
Not counting the brand of Sunni Islam practised by the so-called Islamic State, there is probably no religion in the world that comes in for more flak than Scientology.
Meeting forensic patients for the first time could occasionally be an unnerving experience. They often came across as mild and gentle people, but the details of the crimes were harrowing in the extreme.
Celebrity is quite a fraught word. It is not something I aspire to, but I can certainly see why it could be.
I would love to make a film in the outback or in Papua New Guinea, in Port Moresby. I know that it's not in Australia, but it's not too far.
In my normal way of doing things, there's a little bit of 'going native' that takes place, where you're in a world long enough, you can't really help but start to see things in a nuanced, more humanistic way. Just because you're with people and you start to, in general, slightly like the people you're with.
If I actually invited someone to make a documentary about me, and I said, 'Anything goes', and then I refused to answer any questions, that would be inconsistent.
There are fear mongers who talk about Islam as somehow it is an incubator of hate... remember Christians, like the Westboro Baptist Church, are just as capable of promoting intolerance.
As much as the glasses, it's the Englishness and the gangliness. The apparent lack of muscularity... they indicate I'm not a macho man.
I feel like, if there's an elephant in the room, I'd really like to start off by introducing the elephant in the room. And sometimes it's funny.
I'm following my interests, and there's something about investigating the world and creating a watchable, entertaining programme out of it that is deeply satisfying.
Prisons and jails, I tend to feel that you're actually safer as a journalist than you might think, certainly more than it appears.
Look after your body, because I'm 44, and things are happening that I never dreamed of - like bad joints and man boobs!
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.
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 never misrepresent my position - you've got to be strong enough to make the argument and marshal the case.
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.
