The history of cinema in the GDR has so far been written primarily as a state film policy and production history. However, the personal experiences of GDR cinema vistiors are considered to be almost unexplored, and a historically unique cinema and fan culture threatens to be forgotten over time. The goal of the research project "Cinema in the GDR" is to preserve the knowledge and memories of East German cinema from the perspective of contemporary witnesses. To this end, the project staff developed an interactive platform that is now being made available to the public.
