Nathan Hilu is 90 years old and he cannot stop drawing. Since he stood guard at the Nuremberg Trials as a young U.S. soldier, his mind has replayed the same scenes on repeat, and for decades, he's been getting them all down on paper. Nathan-ism is a documentary portrait of memory, obsession, and what it means to be a first-hand witness to history. But the deeper the filmmakers dig, the more they wonder: what does memory actually preserve, and what does it quietly rewrite? Unsettling, beautiful, and genuinely one of a kind.

Why This Film Matters: We are living through a moment when the last first-hand witnesses to the Holocaust and the Nuremberg Trials are leaving the world, and the question of what comes after their testimony is urgent. Nathan-ism also raises something deeper: the relationship between memory, trauma, and truth. As neuroscience reveals more about how memory is reconstructed rather than recorded, and as deepfakes and AI make visual "evidence" increasingly unreliable, Nathan's compulsive drawings become a meditation on what it means to bear witness in a world where history itself is contested. Essential viewing for an era drowning in misinformation.
