Howlings in Favour of De Sade (1952)

Debord directed his first film, "Hurlements en faveur de Sade" in 1952 with the voices of Michele Bernstein and Gil Holman. The film has no actual images; instead, it shows bright white when there is speaking and black when there is not. Long silences separate speaking parts. The film ends with 24 minutes of black silence.
