If you look at the whole life of the planet, we - you know, Man - has only been around for a few blinks of an eye. So if the infection wipes us all out, that is a return to normality.

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.

It slightly depends on your perspective, sort of how you look at these things, but when I sit down to write a script, I'm not planning to write a script; I'm planning to make a film, and so I only see the script as being just a step there.

The thing video games had to learn was to write, which is not to let people choose their own stuff, but actually prescribe it. To say, "This character is not a blank canvas that you can project onto. I'm going to tell you what this character is like. And I'm going to tell you what happens to them. You're going to feel involved in other ways." Video games made the mistake of thinking everything had to be projectable, and this doesn't do that at all.

I can kid people, including myself, into believing that something on the page will work. But when you film it, you just think, "Oh ...".

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've written original material before, where I've come up with the idea and the characters myself, and that's definitely very different to working with someone else's characters and stories.
