As a director, Rudolph Herzog is best known for the crime series The Heist, which aired on Channel 4 (U.K.) and was called “riveting” by The Daily Telegraph. His documentary on humor in the Third Reich, Laughing With Hitler, scored top audience ratings on German Channel 1 and was also broadcast in English translation on the BBC. He is the son of the celebrated filmmaker Werner Herzog. He lives in Berlin.

All but forgotten today is the surprising number of caricatures and books mocking Hitler and the Nazis from Germany and around the world. Rudolph Herzog explores when humor could get one killed—and what Dr. Seuss did about it.
