During WWII the Nazis seized the operations of dormant production companies—notably those of Jewish producers who were unable to work. Robert Dorfmann and Pierre Braunberger hid out together during part of the war, then Braunberger was interned as was producer Anatole Dauman. After the war Braunberger regained possession of his old office and went right back to work. The French government reluctantly funded the production of Night and Fog.
