I find people confusing.

My book has a very simple surface, but there are layers of irony and paradox all the way through it.

I have very fond memories of swimming in Walden Pond when we lived in Boston. You'd swim past a log and see all these turtles sunning themselves. Slightly disturbing if you thought about how many more were swimming around your toes, but also rather wonderful.

There was a time in my life when I was going in and out of houses that were extraordinarily different - from a working-class terrace in Northampton to the homes of friends who were really very wealthy. It was quite an odd position to be in, I realise looking back, and quite a nice one.

Prime numbers are what is left when you have taken all the patterns away. I think prime numbers are like life. They are very logical but you could never work out the rules, even if you spent all your time thinking about them.

I was born too late for steam trains and a lazy eye meant I'd never be an astronaut.

You make a film you feel is as real as possible and hope people react as though it were real.
