The other day in the local library I found a copy of: A Decade Under the Influence, The 70's flims that changed everything.
It's three hours of the best interviews with Hollywood insiders I've ever seen.

After sound editing was considered "technical" and became mans work...) and Walter Murch discusses in very broad strokes his approach to editing.

sound interesting ill have to check it out
