One of the most amazing, spine-tingly wonderful bits of cinema I've ever experienced is that 33 minutes of silence in Rififi. Apparently, Georges Auric was not thrilled with the idea of silence for the heist scene. When he saw the silent version vs the version with his music, he admitted that Dassin was spot on.
(Okay, not the scene I was talking up earlier, but something almost as wonderful.)
Anyway, just read that Dassin passed away the other day in Athens. He was 96.
