I know that sounds contradictory - you're going on a journey, but once you know who your characters are, you become more disciplined and you film less and less.

I remember very clearly when I found my first soulmate, it was actually in my late 20s, that wonderful feeling of being accepted by people.

The biggest misconception about me is perhaps that I film all the time and film everything randomly. The truth is I film very little and always when something excites me and seems to mean something for the film.

I don't have any advice at all. I think we all make the films that reflect the kind of people we are; we all make such different films. There's not just one way of doing it.

I don't want the people I'm with on this journey to feel like I'm filming them all the time. I don't want them to constantly feel as though they're being watched. So I will have the camera ready at all times, but I will only film when something is really worth filming. Those are the moments when the person being filmed is usually not aware of it.

The magic of documentary is that I keep being surprised and amazed by the things I film.

There's no point in making something if you're not falling in love with the people you're filming and you want them to really enjoy you being around. It would be weird if, when you're making a film, you don't think it's going to be the best ever or the worst ever - I guess it goes from one feeling to another.
