Description: A Sixth Part of the World is Vertov's "state of the USSR report", an extraordinary compilation of images from throughout the Soviet Union that chronicles the spread of the Bolshevik Revolution as well as the technological changes affecting the lives of Soviet citizens. Constructed like a piece of music (a contrapuntal structure, recurring themes, crescendos and diminuendos, prestos and lentos, etc.), A Sixth Part of the World is a film of undiminished power and formal artistry. 　　Source : www.seagullfilms.com
