I think everything I write is from an atheist perspective. I mean, it's partly from an atheist perspective because I'm an atheist, and I'm just not really interested in religious-based questions.

I don’t keep a travel diary. I did keep a travel diary once and it was a big mistake. All I remember of that trip is what I bothered to write down. Everything else slipped away, as though my mind felt jilted by my reliance on pen and paper. For exactly the same reason I don’t travel with a camera. My holiday becomes the snapshots and anything I forget to record is lost.

If I'd learnt one thing from travelling, it was that the way to get things done was to go ahead and do them. Don't talk about going to Borneo. Book a ticket, get a visa, pack a bag, and it just happens.

I never feel a huge need for backstory in my novels or films. Quick sketches are often enough. When you encounter people in life - like a chance encounter at a bar or wherever you happen to be - you make these incredibly quick, quite intricate decisions about people based on very small amounts of coded information. We're good at that. Long descriptions prior to meeting someone or as you're getting to know them almost don't work.

I used to think about video games, "This is clearly an amazing, new narrative medium, and it's going to be mind-blowing when people get to grips with what's possible within this medium." It took us a century to get really good at film. Video games are at a much earlier stage.

The truth is, I hadn't grown up really wanting to be a writer. The whole thing was a weird aberration in some ways, and I didn't feel personally connected to the level of success I had with it - the success of sorts, I guess.
