His final work, "Salò" ("Salò, or the 120 Days of Sodom", 1975), exceeded what most viewers could accept at the time in its explicit scenes of intensely sadistic violence. Based on the novel "120 Days of Sodom" by Marquis de Sade, it is considered Pasolini's most controversial film. In May 2006, "Time Out"'s Film Guide named it the "Most Controversial Film" of all time. Salò was intended as the first film of his "Trilogy of Death", followed by an aborted biopic film about Gilles de Rais.
