(Yes, he wrote it in all caps - except for one part where he accidentally un-cap-ified it.)
It’s an excellent 5-minute-university style how-to course in writing drama (or indeed anything, I think) for a medium that is still relatively new. Mamet writes like a house on fire, and he understands the screen as a medium. He advises to write as if the characters can’t talk, to focus on the visual.
If you write for idiots, only idiots will watch.
