After World War II, he and his wife Berta Drews were imprisoned by the Soviet Army in June 1945, first in Berlin-Hohenschönhausen, then in the former Nazi concentration camp Sachsenhausen, where he died during an appendix operation in September 1946. His remains were found and identified in an unmarked mass grave in a forest near Sachsenhausen in 1994.
Some published reports state that George actually died of starvation in the Soviet detention camp of Sachsenhausen. According to these, the authorities pressured the camp physician to report the death as following an appendectomy.
Although it is inaccurate to say he is actually a character in Peter Handke's "anti-play," "The Ride Across Lake Constance," his name is used as a designation of a character, as are the names of other celebrated actors of the German cinema, Elisabeth Bergner, Erich von Stroheim, Emil Jannings, Henny Porten and the twins Alice Kessler and Ellen Kessler.
Is buried in the Städtischer Friedhof Berlin-Zehlendorf.
Formed his own production company at Tobis in 1942.
