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.
