Claude Lanzmann’s ‘Shoah’ is a memorable film. Not because of what it says. But because of its refusal to say anything at all. The theme of Shoah is the Holocaust, in which over six million Jews were murdered by National Socialist Germany. But to state the theme in this way is to already go beyond the film. Shoah can be classed as a documentary, in that it features interviews about events to which the interviewees were eyewitnesses. But it does not document anything, or try to explain anything. If there is a message, it must be worked out by the viewer, in subjective imagination. Which puts the question to me.
