You could make a feature about the world of tickling. You could include female ticklers and you could find out why people are ticklish, but I don't think it would be a great documentary, when you're spending 90 minutes just finding out about the physiology and psychology of tickling.

It's easy to get young gay men to tickle each other, right? Let's come up with a challenge: Let's get heterosexual men. How do we do that? We make it a competition, because then it's not gay. That explains the antipathy behind the gay-journalist comment.

Reality TV has ruined people's ability to watch documentary.

In New Zealand, we have a one-party disclosure system, where if one of you knows you're being recorded, it's completely fine. It doesn't matter if the other person doesn't know. Look, I'm not breaking new ground by recording people who don't want to be recorded.

It's unfortunate we live in a society where "gay" is an insult. To some of these boys, who are from really red states and have families with military history, to be called gay is the worst thing imaginable, and that's used against them. It's really interesting that these are the people drawn into the tickling world. If the people drawn into competitive endurance tickling, even if they were straight, came from liberal, accepting backgrounds, the backlash of calling them gay wouldn't be a problem. But it's a problem because of where these people are from. That's really fascinating to me.

I was tied down in that chair for 10 minutes and experienced what it was like to be completely powerless while someone else has complete dominance. It's sadistic, even though I find Richard to be a really lovely human being. That's what the whole film "Tickled" is about. It's not a film about tickling, but I think tickling offers a really good visual metaphor for the much bigger ideas that we were trying to get at about power and control - by people who have a lot of money - over people without money and who have no power in the relationship.
