Why do so many multi-writer films stink out loud?
Because writing is solitary. It’s a vision thing. You can’t listen to other people while you’re talking. You can’t explore your vision while others are trying to make you see their vision.
Putting a group of writers in a room is like putting a half dozen cats in a box. Someones going to get f*cked, someones going to get scratched and someones going to wind up curled up in a ball in the corner.
