Served in the German Army during the First World War.
Tall, gaunt, radiating illness. Movements were often slow and deliberate, struggling against the dark forces within him.
Das Kabinett des Dr Caligari  is a visual treat (has to be the story is pretty lame and there is no sound).
Made films about Europe, came to England and made The Wandering Jew 
Was detained briefly when he returned to Germany (he had a Jewish wife).
After this he made sure he remained in England.
When war broke he was sent to the US.
He is the fellow shot down on the phone in Casablanca
