To subdue film to the goals of propaganda (Gleichschaltung), the Nazi Party subordinated the entire film industry and administration under Joseph Goebbels' Ministry of Propaganda, and gradually nationalized film production and distribution. A state-run professional school for politically reliable film-makers (Deutsche Filmakademie Babelsberg) was founded, and membership of an official professional organization (Reichsfilmkammer) was made mandatory for all actors, film-makers, distributors, etc. The censorship that had already been established during World War I and the Weimar Republic was increased, with a National Film Dramaturgist (Reichsfilmdramaturg) pre-censoring all manuscripts and screenplays at the very first stages of production.
