After all, Jim and Ray went (and met) at UCLA film school. I have read John and Ray's book, but of course, most of the information you will find is on Jim. In the latest book about Jim, "Friends Gathered Together", many mention how Jim loved movies a lot more, and I've heard him mention this during interviews. I think Babe Hill said "The movie "Ana-ta-Han" left the biggest impression by his professor (and director) at UCLA, Josef von Sternberg.... I also read this from "Summer With Morrison". It was also written in one of Jim's notebooks, "The Battle of Algiers" with "1966" on top. I've heard Jim say he loved cinema verite (documentary), and he liked the Novelle Vogue (New Wave of the 60s)
I know Ray liked "Les Mepris" (Godard), and mentioned how great "400 Blows" is. He also throws in the Italian director Olmi, but I've only seen one or two.
