If screenwriter/director Avary doesn't reveal enough for you in his Q&A session with the Guardian, go to his weblog--which he must deplore. And when you view his webcam, he may flip you off personally.
He was working on the script for David Fincher's remake of Dogtown and Z Boys but the Guardian has him adapting Bret Ellis's Glamorama now. But since I missed his garage sale (an army of professional rummage sale zombies rummaged it clean as soon as the garage door opened), I'm not the most up-to-date source of Avary goings on.
