The provocative Italian filmmaker Elio Petri’s most internationally acclaimed work is this remarkable, visceral, Oscar-winning thriller. Petri maintains a tricky balance between absurdity and realism in telling the Kafkaesque tale of a Roman police inspector (a commanding Gian Maria Volontè) investigating a heinous crime—which he himself committed. Both a compelling character study and a disturbing commentary on the draconian government crackdowns in Italy in the late 1960s and early ’70s, Petri’s kinetic portrait of surreal bureaucracy is a perversely pleasurable rendering of controlled chaos.
