Salò, or the 120 Days of Sodom, commonly referred to as simply Salò, is a 1975 Italian-French art film written and directed by Pier Paolo Pasolini, with uncredited writing contributions by Pupi Avati. It 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. The film also contains frequent references to and several discussions of Friedrich Nietzsche's 1887 book On the Genealogy of Morality, Ezra Pound's poem The Cantos, and Marcel Proust's novel sequence In Search of Lost Time. It was Pasolini's last film; he was murdered shortly before Salò was released. Because it depicts children subjected to intensely graphic violence, relentless sadism, sexual depravity, and horrific murder, the film was extremely controversial upon its release, and remains banned in several countries. For instance, it was only in the year 2000 that it was granted an uncut release in the UK. The film focuses on four wealthy, corrupt fascist libertines after the fall of Benito Mussolini's Italy in July 1943.
