Gil J. Wolman

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.

The film was shown for the first time on 11 February 1952 at the 'Avant-Garde 52' cinema club. It consisted of blank illumination projected onto a weather balloon, accompanied by a staccato spoken soundtrack. The film was banned by the French censors on 2 April 1952—when the Letterists visited the Cannes Film Festival the following month, they were forced to restrict the audience to journalists only. The text of the soundtrack was published in the sole issue of the Letterist journal Ion (1952; reprinted Jean-Paul Rocher, 1999), and later reissued in a separate edition augmented with associated texts (Editions Allia, 1994). Ion also included the text of Guy Debord's film Howls for Sade, which was dedicated to Wolman and featured his voice in its own soundtrack.

The film consists of a series of sung aphorisms and Lettrist poems, a compendium of almost all the phonetic works François Dufrêne had produced up to that point.
