I think a lot of people - by the time I came back with a script I liked, which took me many years, they'd forgotten who I was. Doors all the time are slamming, you meet friends that you've had for years, you'd go to the studio, and they'd say things to indicate clearly that they hadn't read it, or that they'd had their assistant sort of skim it. They wouldn't buy it. They wouldn't make it.

The only way you can stay on top is to remember to touch bottom and get back to basics.

Once you've got a concept and a sense of themes and what it's about, then you can start to add your plot and sort of Tetris in all of the elements that you want to see, but also attach them to something that has cohesion, like a mold.

You have to keep surprising your audience.

I'm ashamed to say this, but I watched every episode of 'Starsky and Hutch' as a kid. I loved that show, but now I think it's stupid - they'd have a car chase for no reason, then Paul Michael Glaser would shoot the car and it would blow up.

An action film can have too much action; picture an equaliser on a stereo, with all the knobs pegged at 10. It becomes a cacophony and is, ultimately, quite boring.

Writing scripts is a laborious job that can be a real pain.
