Some documentaries are made by people who are driven more by one particular story, or have different backgrounds or ambitions, but I'm always looking for projects that let me be the best filmmaker I can be, and to be stretched and grow further.

I love great locations in movies, and I couldn't believe I'd never seen a landfill on screen before. It was the most haunting place.

I love making fiction films as well as nonfiction ones, and hope to keep challenging myself to make better and better work.

I love my work, apart from when it's driving me crazy. But I get to be interested in stuff and think like a filmmaker as I'm buzzing about the world and then see an opportunity to make a film, and then make it happen.

As parents, we need to send our kids back to 'old-fashioned' outdoor summer camps, which have been on the decline as the demand for sports and academics-based camps has risen. We need to fight budget cuts to public parks programs and resist closures of public swimming pools and playgrounds.

It was tennis that got me started in business. When I was 16 and about to embark on my A-levels, I set up a tennis academy and became one of the youngest qualified tennis coaches in the country. It did well; by the time I was 19 I was able to buy my first house.

It's a team game, but you've got to have individuals that really want the ball and want the pressure of being there to help get in a position to win.

My dad had a spell when he came out of coaching doing some work with underprivileged children on quite a rough council estate in Southampton to help the kids and take them out to places. I used to go along with him. I used to play football with them, mess about with them. I was only 13 or 14 and became good friends with them.
