Chasing Train: A Documentary About John Coltrane

Bob Greene: The first thing when I'm deciding if I want to do a documentary or not is, A, what's the story? Is the story compelling enough, strong enough that it can be a feature documentary as opposed to just an hour on discovery or the history channel? This story was so compelling, and it was like the best of a spy novel. So we put my researchers on this. And I think had we not found this 60 minute version, we would probably not be here talking today. We would not have been able to make the film, but we did find it. That's the foundation of the film itself. All of this film that was shot on the tour.
