This is currently playing on the Sundance channel, and I just finished it. In a word: great. Basically the film is a lot of recent footage of Tom interspersed with interviews with Jerry Wexler, Arif Mardin, Ahmet Ertegun, Eric Clapton, Ray Charles, several members of the Allman Brothers, etc all and bits and pieces of archival footage. A lot of the anecdotes are nothing new (going to Stax to fix their machine, Eric and Duane meeting, etc), and a few bits weren't 100% correct, but nevertheless, it was great to see these guys talk.
One of the highlights is Dowd sitting in front of the console mixing Layla. "Ok, let's just hear Eric and Duane's solos now." It literally brought a smile to my face.
There's quite a bit of talk about 8-track, albeit nothing about the Atlantic fire

A minor quibble, although one I think is important - Tom really looks great throughout the movie, and the only mention of his passing is a memorial screen at the end of the movie. I think that might be a bit jarring to someone who watched the whole movie not knowing he had already passed away.
At any rate, the movie is still great. My hope is there will be a DVD sometime in the future with additional stuff cut out of the movie.
