From the Berlinale website:
From February 12 to 15, 2010, a unique art installation entitled “The Curtain” will tell of the magic and power of the cinema: renowned artist and international Korean-American designer Christina Kim will create a 300–square-metre symbolic movie-theatre curtain from recycled film and Berlinale billboards, DVDs, and other film-related materials. After the opening ceremony on February 12, the world premiere of the restored original version of Fritz Lang's Metropolis will be transmitted live to the public from the Friedrichstadtpalast to a screen at the Brandenburg Gate. The public is invited to enjoy this significant moment in the history of film - free of charge - at this very special setting.
