Also, here's a decent documentary about Blade Runner (52 minutes). There's not a lot new in there if you've read Future Noir: The Making of Blade Runner (which you should) but at 40:00, there's a deleted scene that I hadn't seen before of Deckard visiting Holden in the hospital.
Update: The VH1 showing was the same as the Sundance showing, except they omitted three more acts: Surf Punks, My Beach My Wave; The Cramps, Tear It Up; and Invisible Sex, Valium. Leaving out that Cramps performance was nuts -- it's one of the high points of the movie! Both showings omitted three other performances, which I haven't seen since the 80s: Gary Numan Down in the Park (he drove around the stage in a little bumper car!); Skafish, Sign of the Cross; and Splodgenessabounds, Two Little Boys.
