Behold, another batch of titles is on its way to the online store. Today’s additions include Flavio Frederico’s “Boca,” the German edition of Fritz Lang’s “M,” and Peter Bogdanovich’s “Paper Moon.” Prior to becoming (as Alex Ross Perry once put it at an AFI Fest screening) “America’s greatest living filmmaker,” Bogdanovich got his start as a wunderkind programmer and critic before cranking out stone cold masterpieces like “The Last Picture Show” and “Paper Moon,” only to have his career derailed multiple times by personal scandals and commercial failures.
