 Basically unlimited amount of versions. The film is different every time it screens. You've made documentaries about Mavis Staples, about Wilco, about a font, Helvetica. Why Brian Eno? Brian Eno is someone who I've been a fan of for decades. Yes, for the music, but also for his approach to creativity. In the version of the film I saw, he was part of what I'll call the art rock movement.
