Fritz Lang’s 1927 film Metropolis is a science fiction classic, a dystopian story of the conflict between the working classes and the owning classes. But American and European audiences have not been able to see the full film in decades -- it was severely cut down for American release. But a full-length version ended up in the private collection of Argentine film critic Manuel Peña Rodríguez, and from there made its way to Argentina's Museo del Cine; and with some help from digital restoration techniques, the (nearly) complete version is back in circulation.
