Indelible stories from survivors and chilling present-day footage of the former camp combine to make this short, stark yet hopeful film. Look at the world in 2025 and you can easily see why it is such vital viewing

This month is the 80th anniversary of the liberation of the Auschwitz concentration camp in German-occupied Poland, and, in Jordan Dunbar’s documentary What Happened at Auschwitz, there is a sense of these chances to remember running out. Most obviously that’s true in terms of being able to speak directly to the survivors: Dunbar meets a handful of them, and their clarity and focus are undimmed, yet their numbers are declining.

Dunbar, however, assigns his subject matter another, different urgency. We live, he observes, in an era of disinformation and rising hatred. A terrifying percentage of online content and commentary about the Holocaust questions whether it happened or celebrates that it did. Less than a century since this appalling crime against humanity, the principle of Never Again is wobbling.
