There's one massive problem with coming from writing novels into screenplays that I've discovered over the years, which is that you've got too much facility on the page. In novels, you can persuade people of things that work that don't really work.

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.

Every dream that anyone ever has is theirs alone and they never manage to share it. And they never manage to remember it either. Not truly or accurately. Not as it was. Our memories and our vocabularies aren't up to the job.

Vietnam, me love you long time. All day, all night, me love you long time. (...) Dropping acid on the Mekong Delta, smoking grass through a rifle barrel, flying on a helicopter with opera blasting out of loudspeakers, tracer-fire and paddy-field scenery, the smell of napalm in the morning. Long time.

There's this saying: in an all-blue world, colour doesn't exist... If something seems strange, you question it; but if the outside world is too distant to use as a comparison then nothing seems strange.
