I just watched the theatrical cut with Francis' commentary last night. Its awesome. I also watched a couple of the featurettes on the second disc on the music for the film. Hearts of Darkness isnt included, but theres footage from it on there.
In one part of the film, Francis said that after the film was done and they were editing it, he went to none other than Akira Kurosawa for some advice on what to do with certain scenes. He said Kurosawa not only gave him advice, but he gave him TOO MUCH advice. He was really honored that Akira was so interested in the film.
NOTE: I didnt realize the films were cut up over two discs until I watched it last night. So that makes this set not perfect, but still its the best release of Apoc Now on DVD you're gonna get. I'd buy this set just for the commentaries with Francis alone. Its really great to listen to him talk about making the film as you watch it.
