From May to October 1974, Peter Voigt filmed at the Berliner Ensemble (BE) during the 25th anniversary of the theater’s founding. Voigt, a member of the BE himself in the 1950s, interviewed theater technicians who had been part of the world-famous ensemble for decades. Sharing experiences, memories and impressions from their particular point of view, they paint an intriguing picture of the theater’s history. This documentary, originally shot on 16mm film, includes rarely-shown photographs, set design sketches and historic sound recordings, as well as clips from BE rehearsals and productions of Cement, Coriolanus, In the Jungle of Cities, The Mother, Señora Carrar's Rifles and The Threepenny Opera.
