Last Tuesday Paula Félix-Didier travelled on a secret mission to Berlin in order to meet with three film experts and editors from ZEITmagazin. The museum director from Buenos Aires had something special in her luggage: a copy of a long version of Fritz Langs Metropolis, including scenes believed lost for almost 80 years. After examining the film the three experts are certain: The find from Buenos Aires is a real treasure, a worldwide sensation. Metropolis, the most important silent film in German history, can from this day on be considered to have been rediscovered.
