Overall, Debord challenged the conventions of filmmaking; prompting his audience to interact with the medium instead of being passive receivers of information. As a matter of fact, his film "Hurlements" exclusively consists of a series of black and white screens and silence with a bit of commentary dispersed throughout. Debord directed his first film, "Hurlements en faveur de Sade" in 1952 with the voices of Michèle Bernstein and Gil Wolman. The film has no images represented; 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. People were reported to have become angry and left screenings of this film. The script is composed of quotes appropriated from various sources and made into a montage with a sort of non-linear narrative.
