To get a greenlight with no notes is like skipping three grades in high school. Alan Ball suddenly became that geeky 13 year old senior who goes on to own a multi-million dollar internet startup before he can vote. Here's the funny part. They still changed it. It's one of those scripts that hit the town like a tsunami.
People save it, and pass it around.
Examining some of the changes between the script and the movie is a fascinating exercise in development. As they start, Angela winces and cries out in pain. Now remember that Angela has spent the previous hour and a half talking big about her many sexual partners. Lester does not think that he is having sex with a virgin until that moment. In the movie, Lester stops the moment he realizes that Angela is a virgin.
