Dziga Vertov: Man With A Movie Camera (Soviet Union, 1929)

"This playful film is at once a documentary of a day in the life of the Soviet Union, a documentary of the filming of said documentary, and a depiction of an audience watching the film. Even the editing of the film is documented. We often see the cameraman who is purportedly making the film, but we rarely, if ever, see any of the footage he seems to be in the act of shooting!" Written by George S. Davis

In 1996 Norwegian composer Geir Jenssen ("aka Biosphere") was commissioned by the Tromsø International Film Festival to write a new soundtrack for the movie, using the director's written instructions for the original accompanying piano player. Jenssen wrote half of the soundtrack, turning the other half to Per Martinsen (aka Mental Overdrive). It was used for the Norwegian version, "Mannen med filmkameraet", at the 1996 TIFF. The scored movie was not available after the festival. Soundtrack released in 2001 on CD. This edit of the film contains only the parts written by Biosphere.
