David Cesarani on Lanzmann's Shoah 25 years later, in The New Statesman:
There had never been anything like Claude Lanzmann's Shoah when it was released in 1985. There were earlier documentaries about the Holocaust: Alain Resnais's Night and Fog (1955); the “Genocide” episode of the World at War series, which was broadcast on ITV without any commercial breaks in 1974; Kitty: Return to Auschwitz and Auschwitz and the Allies, transmitted in 1979 on ITV and in 1982 on the BBC, respectively. But they hardly prepared you for Lanzmann's nine-hour epic.
Lanzmann eschewed the use of archive footage. He refused to include photographs. There is not a single image of a corpse in the entire film. Instead, there are interminable landscape shots of woods, forest clearings and empty fields. And trains: trains crossing the screen, filling the frame, close up, at middle distance or silhouetted again the horizon. The constant motion of camera or of locomotive drives the film along.
Then there was the director himself: a burly figure, often wrapped in a coat against the Polish winter, interviewing his witnesses. Lanzmann was insistent, ironic and sometimes faintly contemptuous. He showed himself lying to Franz Suchomel, a former SS guard at Treblinka, who was being captured by a hidden camera, brazenly flouting the ethics of documentary film-making.
Although Shoah has been hugely influential, it was so unconventional that it remains almost sui generis. Lanzmann declined to incorporate stock footage because it was created either by the Nazis or after the camps were liberated. To him, the monochrome newsreels short-circuited our engagement with the past by offering reassuringly familiar imagery. Shoah offers no such comforts.
