Shot on the war-ravaged streets of Rome in 1945, Robert Rossellini’s Open City brought the European postwar experience home to distant audiences and established the style known as neorealism, which quickly became the dominant mode of Italian cinema. Though this drama about the Italian resistance featured some professional actors (notably Anna Magnani), it’s most notable for its documentary technique and intensity.
