Paolo Pasolini´s Salo 120 Giornate di Sodoma is based on the book The 120 Days of Sodom, by the Marquis de Sade. The story is in four segments, inspired by Dante's Divine Comedy: the Anteinferno, the Circle of Manias, the Circle of Shit and the Circle of Blood.
Director John Waters said "Salo is a beautiful film...it uses obscenity in an intelligent way...and it's about the pornography of power." The film was trying to present fascism in visionary terms rather than as the logical or historical consequence of Sade. The viewer becomes complicit in the objectification of the human through the visual regime of the film. For this reason it is an anti-fascist film.
The tone of Pasolini polemic is “apocalyptic, not merely critical of Western society’s immorality, using sex in Salo as a metaphor for power relationships, after having taken the opposite position a few years before in his cinematic adaptations of The Decameron (1971), The Canterbury Tales (1972), and Arabian Nights (1974), where he depicts sexuality as a space of transgression and a vital rejoinder to every act of domination.
