My first attempt at writing was very unstructured and formless, with shifting points of view. I was trying to understand how long form might work, and I realized I had something shapeless. It was a total car wreck. But I still felt I could pull it off. So I ditched that attempt and started writing in the opposite manner, in first person, with a driving narrative.

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.

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

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.

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.

Though I walk through the valley of death I will fear no evil, for I am the evilest motherfucker in the valley
