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 is concerned with historical events and includes the testimony of 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.
