Saw documentary Chasing Trane at Santa Barbara Film Festival last night. Quite good, though it leaves out lots and at times is even a bit misleading. Most important it has quite bit of newly discovered footage of Coltrane. And the director claimed that it even has some newly found music: they discovered some of the 1966 Newport performance on the tail of a Charles Lloyd reel in the Warner Bros. vaults. (However I see in the Trane discography that it's listed as being released on what I presume is a bootleg label.)
The film is a good introduction to Trane and has interviews with many musicians. (e.g. Benny Golson, Jimmy Heath, McCoy Tyner and Sonny Rollins.) Though my favorite film interview about Trane is one in another documentary where Elvin Jones, looking like he really means it says, "He was a saint."
