Chelovek s kino-apparatom (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!
