Seldom has the rediscovery of a cache of lost footage ignited widespread curiosity as did the announcement, in July 2008, that an essentially complete copy of Fritz Lang's "Metropolis" had been found. The curator of the Buenos Aires Museo del Cine discovered a 16mm dupe negative that was considerably longer than any existing print. It included not merely a few additional snippets, but 25 minutes of "lost" footage, about a fifth of the film, that had not been seen since its Berlin debut. The discovery of such a significant amount of material called for yet another restoration - "The Complete Metropolis."
