I always seem to enjoy documentaries about filmmaking. I've watched really good films about editing and cinematography. This one is about screenplay-writing. It's a series of talking-head interviews with screenwriters at varying points in their careers. There are plenty of great stories about breaking into the business. They talk about the creative process and what it's like dealing with studio executives, directors, and actors. It offers about an hour of extra footage - something I always appreciate. If behind-the-scenes stuff interests you, I think you'll enjoy it.
Netflix it HERE.
