Ebert update (1 of 3): Lost parts of "Metropolis" found

In a commentary posted 4 August, Roger Ebert writes:

It is the most sensational find in recent film history. A nearly-complete print of Fritz Lang's "Metropolis" (1927) has been discovered in Buenos Aires, 80 years after it was thought a quarter of the film was lost forever. Called by many the most important of German films, one of the landmarks of silent Expressionism, its plot had several loose ends that will now be repaired.
