When Christopher Nolan began writing the screenplay for Oppenheimer in the early 2020s, his teenage son questioned whether anyone still cared about nuclear weapons. By the time the film was released in 2023, Russia’s invasion of Ukraine and Vladimir Putin’s nuclear saber-rattling had thrust atomic anxieties back into public consciousness.
The timing was coincidental, but it highlighted precisely why Nolan’s recent work matters: He creates true blockbusters that force audiences to grapple with humanity’s most profound existential challenges.
Oppenheimer, which won both Best Picture and Best Director in 2024, represented the culmination of Nolan’s long-running artistic exploration of how scientific advancement can simultaneously fulfill humanity’s greatest hopes and create its most terrible dangers. The film chronicles J. Robert Oppenheimer’s journey from brilliant theoretical physicist to “father of the atomic bomb,” capturing both the intoxicating intellectual achievements of the Manhattan Project — what Oppenheimer himself called the “technically sweet” — and the moral horror of unleashing nuclear weapons on the world.
“Part of the intention of the film is to reiterate the unique and extraordinary danger of nuclear weapons. That’s something we should all be thinking about all the time and care about very, very deeply,” Nolan told the Bulletin of the Atomic Scientists last year. But beyond just raising awareness, the director aimed to strip away decades of dry policy papers and arcane philosophical frameworks that have normalized the existence of nuclear arsenals quite literally capable of destroying the world. In Oppenheimer, Nolan renewed the terror at the heart of these weapons viewed through the eyes of those scientists who oversaw their terrible birth.
This focus on making existential risk real and immediate rather than abstract has been found throughout Nolan’s recent work. His 2014 film Interstellar envisioned humanity’s desperate search for habitable planets as environmental catastrophe renders Earth increasingly uninhabitable. 2020’s Tenet, released in the teeth of the Covid pandemic, explored themes of technological knowledge that, once uncovered, cannot be put back in the box. (And even if you struggle, as I initially did, with Tenet’s non-linear chronology, you can appreciate how great stars John David Washington and Robert Pattinson look in those suits.)
His films refuse to paint scientists as either heroes or villains, instead showing them as brilliant but fallible humans wrestling with the consequences of their discoveries — consequences we all now have to live with. But Oppenheimer represented his most direct confrontation yet with how scientific progress creates unprecedented moral burdens.
The film’s pivotal moment — the moment that initially inspired Nolan to begin the project — comes when Oppenheimer’s team at Los Alamos realizes there was a small but real possibility that the first nuclear test might ignite the atmosphere and destroy all life on Earth. After some debate — with Matt Damon’s brusque Gen. Leslie Groves playing the shocked audience surrogate — they proceed anyway. “That struck me as the most dramatic situation in the history of the world,” Nolan told the Bulletin. “That’s a responsibility that nobody else in the history of the world had ever faced.”
What makes Nolan’s treatment of these weighty themes remarkable is his insistence on tackling them through the lens of mass-market entertainment rather than niche documentary. He employs the cutting edge of big-budget filmmaking — from practical effects to IMAX cameras — to make abstract dangers feel immediate and real. For Oppenheimer, he even refused to use computer graphics for the nuclear explosions, believing that only practical effects could convey the genuine terror such weapons should inspire. And audiences’ reactions proved him right.
The approach has proved remarkably effective at reaching audiences that might otherwise tune out discussions of existential risk — and as someone who has written a book on precisely that subject, I can tell you that’s no easy feat. Oppenheimer earned over $950 million globally while sparking meaningful public discourse about nuclear weapons.
The director’s greatest concern now is how easily society can normalize even the most terrible risks, and why it is so important to fight back. When he accepted a BAFTA award for Oppneheimer, Nolan told the audience, “Our film ends on what is a dramatically necessary note of despair, but in the world all kinds of individuals and organizations have fought long and hard to reduce the number of nuclear weapons.” Still, he continued, “of late, that has gone the wrong way,” as the nuclear arms control regime teeters on collapse.
Through films that marry entertainment with ethical weight, Nolan has emerged as one of Hollywood’s most effective voices for keeping humanity’s greatest challenges squarely in the public consciousness. He reminds us that existential risks aren’t just abstract policy issues — they’re profound human dramas that demand our attention and moral consideration. In an era when many choose to look away from humanity’s gravest threats, Nolan insists we look directly at them, in all their terrifying scope and complexity.
