Director Claude Lanzmann spent 11 years on this sprawling documentary about the Holocaust, conducting his own interviews and refusing to use a single frame of archival footage. Dividing Holocaust witnesses into three categories -- survivors, bystanders and perpetrators -- Lanzmann presents testimonies from survivors of the Chelmno concentration camp, an Auschwitz escapee and witnesses of the Warsaw Ghetto Uprising, as well as a chilling report of gas chambers from an SS officer at Treblinka.
