I agree, Armin Wegner would make a very good protagonist for a future film.
Since he was German, it would also be a perfect opportunity to include
the shameful behavior of the German state at that time.
They knew about the genocide, but didn't do anything.
Actually, the Nazis might have learned from the Young Turks how to do it:
Furthermore, Professor Balakian and other historians have traced how some of the German witnesses to the Armenian holocaust played a role in the Nazi regime.
Konstantin Freiherr von Neurath, for example, was attached to the Turkish 4th Army in 1915 with instructions to monitor "operations" against the Armenians; he later became Hitler's foreign minister and "Protector of Bohemia and Moravia" during Reinhard Heydrich's terror in Czechoslovakia.
Friedrich Werner von der Schulenburg was consul at Erzerum from 1915-16 and later Hitler's ambassador to Moscow.
Rudolf Hoess was a German army captain in Turkey in 1916; from 1940-43, he was commandant of the Auschwitz extermination camp and then deputy inspector of concentration camps at SS headquarters. He was convicted and hanged by the Poles at Auschwitz in 1947.
We may never know, however, the identity of the two officers standing so nonchalantly beside the skulls of Erzinjan.
