Chicago Reader review:
'One of the most underrated, neglected, and powerful of Pier Paolo Pasolini's features, this 1967 film, shot in Morocco, is a retelling of the Sophocles tragedy that begins in antiquity and ends in the 20th century, with references to both the fascist period in Italy and Pasolini's own life. With Franco Citti, Silvana Mangano, and Alida Valli. In Italian with subtitles. 119 min.'
