The Althoff Studios (German: Althoff-Atelier) were film studios located in Potsdam outside the German capital Berlin. The studios were constructed in 1939 by the film producer Gustav Althoff who controlled the independent company Aco-Film. The original building was a former restaurant, but Althoff soon expanded the site by adding a larger sound stage. Subsequently they were also home to television production. In 1997 the studios were sold-off for development as real estate.
