The Blue Angel
Jannings is best known for his collaborations with F. W. Murnau and Josef von Sternberg, including 1930's "The Blue Angel" ("Der blaue Engel"), with Marlene Dietrich. "The Blue Angel" was meant as a vehicle for Jannings to score a place for himself in the new medium of sound film, but Dietrich stole the show. Jannings later starred in a number of Nazi propaganda films, which made him unemployable as an actor after the fall of the Third Reich.
