Leni Riefenstahl: what are we to make of her? What did she know? Often described as ‘Hitler’s favourite filmmaker’, she always claimed that she knew nothing of any atrocities. She was a naive artist, not a collaborator in a murderous regime. This documentary wants to get to the truth. But even if you’ve already made your own mind up – I had! – it’s still a mesmerising portrait of the kind of person who cannot give up on the lies they’ve told themselves.
