This experimental film ("Venom and Eternity") by Isidore Isou constitutes the Letterist manifesto of film. Rejecting film conventions by 'chiseling' away at them, Isou introduced several new concepts, including discrepancy cinema where the sound track has nothing to do with the visual track. In addition, the celluloid itself was attacked with destructive techniques such as scratches and washing it in bleach. Causing a scandal at the 1951 Cannes Film Festival, this film was later introduced in the United States where it influenced avant-garde film makers such as Stan Brakhage.
