I lived in Camden, Primrose Hill and Kentish Town for 10 years.

Weirdly enough, I live in London - was born there and have lived there all my life - but I hadn't made a film in London for a long time. I hadn't found the right subject. I liked going away, to some far flung place.

As a filmmaker, you complete a film you have spent years obsessively making, and you know the release prints will never look quite the same; prints get scratched and dirty.

To be teammates in Formula One actually means you are first rivals, not really mates.

There are no drivers like Formula One drivers. They are engineers, in a way. They are driving manual cars one-handed at 200 miles per hour around streets in Monaco. These cars use the ultimate in technology.

I wanted to make a film that wouldn't just appeal to Formula One fans. That's what the great sports documentaries do - 'Hoop Dreams,' 'When We Were Kings' - they're human dramas first, sport second, if at all.
