Salò, or the 120 Days of Sodom (Italian: Salò o le 120 giornate di Sodoma), billed on-screen as Pasolini's 120 Days of Sodom on English-language prints and commonly referred to as simply Salò (Italian: [saˈlɔ]), is a 1975 political art horror film directed and co-written by Pier Paolo Pasolini. The film is a loose adaptation of the 1785 novel (first published in 1904) The 120 Days of Sodom by the Marquis de Sade, updating the story's setting to the World War II era. It was Pasolini's final film, released three weeks after his murder. The film focuses on four wealthy, corrupt Italian libertines in the time of the fascist Republic of Salò (1943–1945). The libertines kidnap 18 teenagers and subject them to four months of extreme violence, sadism, genital torture and psychological torture. The film explores themes of political corruption, consumerism, authoritarianism, nihilism, morality, capitalism, totalitarianism, sadism, sexuality, and fascism. 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. Premiering at the Paris Film Festival on 23 November 1975, the film had a brief theatrical run in Italy before being banned in January 1976, and was released in the United States the following year on 3 October 1977. Because it depicts youths subjected to graphic violence, torture, sexual abuse, and murder, the film was controversial upon its release and has remained banned in many countries. The confluence of thematic content in the film—ranging from the political and socio-historical, to psychological and sexual—has led to much critical discussion. It has been both praised and decried by various film historians and critics and was named the 65th-scariest film ever made by the Chicago Film Critics Association in 2006.
