The actor had come to the Los Angeles Film Festival together with the film's director. After the screening, a member of the audience came up to Röhrig and asked him whether he would like to meet a real former member of the Sonderkommando.

Dario Gabbai, who was deported with his family to Auschwitz-Birkenau in 1944. Of the appr. 2200 prisoners who were forced to work in the Auschwitz Sonderkommando, only about 90 to 110 survived the war. The Nazis usually killed most of them after a few months because they were eyewitnesses to the genocide, and would then replace them with new arrivals. Gabbai is believed to be the last remaining today. [Haaretz 2016].
