Supplemental Documentaries I liked:
+ The Battle Over Citizen Kane
+ The documentary recorded by David O. Russell for Three Kings. George Clooney doesn't seem to be amused while David is filming him with his camcorder while the two are basically still in pre-production talks for Clooney to star in the movie. Mark Wahlberg seems to be zonked out while he was being filmed, and during the premiere, the usher told off David Russell, telling him that his handheld camera is not allowed in the theater, not knowing that the guy he was talking to was the director of the movie being premiered in the theater!
+ I agree with the posts above that the retrospective documentaries included in the Superman: The Movie DVD are quite nice... (wish they just separated this set into two discs instead of making it a flipper, and packaged it a la Citizen Kane, instead of placing it in that ugly snapper case!)
+ I really liked "The Beginning" documentary included in the Phantom Menace DVD... The movie is a bit on the slow side, actually, but the documentary makes you really feel like a "fly on the wall" while Lucas and his team assembles the movie...
Some documentaries that were not included in the DVD release but should have been:
+ Exhausted, a documentary about the life of porn star John Holmes was supposed to be included in the second release of the Boogie Nights DVD (or at least an edited version of it)... unfortunately, this didn't push through because of rights issues or something... watching this could've been a hoot... i've heard that pt anderson borrowed a lot from this documentary with regards to the look of some of the sets in the movie, and the performance of mark wahlberg as dirk diggler...
+ In Defense of Dogma was supposed to be included in the Dogma Special Ed DVD, but was pulled, I think because the docu badmouthed a lot of the studios who chickened out of distributing the movie... Could've been worth watching, if only to see all those people who were protesting the movie without having seen it first (just like the Last Temptation of Christ fiasco)...
