Repeating: For years I've been trying to buy or stream Martin Scorsese and Kent Jones' Letter to Elia, which I saw exactly once at the 2010 New York Film Festival. It's basically Scorsese talking about his worship of Elia Kazan over the decades, and "a delicate and beautiful little poem," as I wrote 13 years ago. It's one of the most touching docs of this sort that I've ever seen.
