Mark Felton is excellent.
Anton Diffring, born Alfred Pollack on 20 October 1916 in Koblenz, Germany, came from a mixed religious background; his father, Solomon Pollack, was Jewish, and his mother, Bertha Diffring, was Christian. He studied acting in Berlin and Vienna before leaving Germany, reportedly to escape persecution due to his homosexuality and the rise of the Nazi regime. He initially settled in Canada, where he began his acting career, and later moved to the United Kingdom in 1950, quickly becoming fluent in English.
Being homosexual and Jewish, yeah, get the heck out of Nazi Germany!
