Ornette: Made in America, Clarke's documentary about the free jazz/ harmolodics pioneer, which features appearances by R. Buckminster Fuller and William S. Burroughs (Cronenberg's film adaptation of Naked Lunch uses some of Ornette's soloing, embodied within Howard Shore compositions; Coleman can be seen playing some of this live on Youtube). Brion Gysin and the Master Musicians of Jajouka, with whom Ornette also recorded, may also be in the film, though as I say, I've yet to see the film, so I'm quite sure what's in it; apparently one sequence deals with Coleman's request to be castrated, so he could dispense with sexual feelings and focus on music, though I am unclear as to whether this operation was ever actually carried out. While I don't know the film (or much of Coleman's bio), I'm very, very fond of Ornette's early recordings with Don Cherry; of his harmolodics stuff, Body Meta is my favourite. Note: photo of Ornette playing at the Cellar in Vancouver in the 1950's, here.
NOTE: There was an error in the Cinematheque's listings for the 31st, and perhaps elsewhere. Please see here for the correct showtimes for Hallowe'en: there is no 5:10 screening of The Connection.
