I don't know nearly enough about pre-World War II German cinema as I want to, or indeed should know. In fact my knowledge kind of starts and stops with the silent era and then begins again with the Leni Riefenstahl propaganda films, such as Triumph Of The Will, which still has some of the most amazing visuals ever filmed, if you can get past the subject matter. Still, Riefenstahl always denied that she knew of any crimes that the Nazis were doing, or any knowledge of any mass slaughter, this despite there being photographic evidence that she was present at a massacre at least once. Still if there's one thing that old Nazis hate it's being called Nazis - just ask the Pope.
Yep, I chuckled a lot.
Ahhhh German cinema, I need to read more about you and expand my knowledge through study, so once I've finished the books I have on European cinema and French Cinema I might track down some German cinema books and immerse myself.
