Pages in the Factory of Dreams - Black Extras in German Feature Films

About

Until 1942 around 100 German propaganda films were made, that were set in Africa. They were produced in Germany, with Black Germans and Africans living in Germany.

What were their daily experiences as Black people during the Weimar Republic and the Nazi Regime?
