Pier Paolo Pasolini’s disappointing 1970 version of the Greek tragedyshot in Syria, Turkey, and Italyoffers soprano Maria Callas in her only film role, playing the lead part but not singing it. Pasolini’s Marxist, Catholic, and pagan impulses infuse the film with some life, but it’s a step backward after Oedipus Rex (1967). It’s worth seeing nevertheless. (JR)
