Actually my favorite commentary moment is on the EP 1 DVD, but I can't check because I use the prequel DVD's as drink coasters now (yes, really) - it might be in one of the supplements... but anyway, Ben Burtt is editing, and he's talking about how George basically makes the movie up in the edit bay as he goes along. The thing is, Ben OBVIOUSLY thinks the whole thing is ridiculous and is trying to figure out how not to come right out and say that. I think he eventually likens all the post-shooting bs to a slippery slope. In any case, the best moment is one where they cut away just as he's saying that the process creates more problems... I think it's actually on the word, "problems" so they could patch it with something more positive. Ben's at Pixar now. He wants to direct. Someplace where they know how to do that kind of thing.
