I felt that in a way, I hated the writing process so much. It's excruciating, as I'm sure you know, and so lonely being in the solitary prison of my office. A lot of brain-wracking. It just felt like it was so much hard work, and I would send it away. I felt as though I was doing all of this heavy lifting, this weightlifting, every day, all day. It was excruciating. And I stayed skinny, and someone else got all the muscles. I was eating all my vegetables, but then I wouldn't get dessert. To me, directing is the dessert.

I think the most important thing is to, without belligerence, stand up for what want. Argue compellingly if someone tries to change your script. Yeah, legally they can if they want to. But rather than give up, as some of the writers do, and just wail about how your script got rewritten, it's much more difficult - but well within the realm of possibility - to argue very sincerely, calmly, and reasonably from your point of view, such that the director or the producer might decide, "All right, let's do it that way."

An action movie should, like any other, follow the narrative traditions of literature. That means there should be subtlety, a slow build and a gradual bringing together of all the separate threads of the plot. To see all of it coming together slowly is very rewarding for the audience.

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.

The other thing being at UCLA was just being in California and around the movie business. Which I honestly believe, and I've told this to screenwriters, you have to do. You have to be there in order to write or direct movies.

Going to UCLA, as far as I'm concerned, afforded me two things. One was the advantage of meeting friends and getting to know a group of guys I hung out with, was chummy with. All of us eventually had success with film. Making films, cutting our own little movies together, 3 in the morning going out and shooting stuff, finding gels that people had thrown away, making our own lights. It was like a frat house for film geeks, the Pad O' Guys. That's what being at UCLA afforded me.
