"The German newspaper Die Zeit reports that a copy of Metropolis -- significantly longer than any known print -- has been discovered at the Museo del Cine de Buenos Aires. The cinematic holy grail is a 16mm dupe negative, derived from a 35mm nitrate print that had been owned by film critic Manuel Peña Rodriguez, who sold it to Argentina's National Art Fund in the 1960s. In 1992, the film was inherited by the Museo del Cine, where it lay unnoticed until Museo del Cine curator Paula Félix-Didier screened the film, acting on a tip from the film curator of the Museum of Latin American Art. After making the discovery, Félix-Didier traveled to Berlin with a copy of the film to show the editors of Die Zeit. According to the initial coverage, "Félix-Didier wanted the news to be announced in Germany where Fritz Lang had worked -- and she hoped that it would attract a greater level of attention in Germany than in Argentina."
The complete restored version, with 25 *lost* minutes, will be travelling the United States!
I don't know about anybody else, but I'm a big old movie fan and this is exciting.
