When Nuclear Thrills Feel All Too Real

The Weight of a President's Decision

When I first read about Alexandre Smia's debut feature, Jupiter, I thought it was a cleverly timed thriller—though I couldn't have predicted just how prescient it would become. The film centers on a newly elected French president, Paul Archambault, who finds himself thrust into the Jupiter command post—a high-security nuclear bunker beneath the Élysée Palace—when a deadly assassination attempt sparks an international crisis. With Russia threatening retaliation and Ukraine under siege, Archambault must make a decision that could reshape the world.

What makes this film so chilling is not just its premise but how it mirrors our own moment in history. When Smia began writing in 2024, Joe Biden was still in the White House. Now, as Jupiter prepares for its Venice premiere, we're witnessing a real-time escalation of global tensions. It's as if the film was written not just about politics, but with it.

"I don't think we're dealing with a dystopian hypothesis at all," Smia tells me. "I think we're dealing with a form of plausible reality. And that's what's completely frightening: it's totally plausible."

A Nuclear Third Age

Smia's assertion that France has entered the "third nuclear age" is more than just a geopolitical rebranding—it's a sobering reminder of how dramatically the balance of power has shifted. France, once a passive observer in nuclear matters, is now a key player, caught between its role as a NATO member and its commitment to sovereignty within the EU. Smia sees this transformation not as an accident, but a consequence of the war in Ukraine.

"We've entered what experts call the third nuclear age," he says. "This is the first time that France has become an actor, whether it wants to or not." That reality is what gives Jupiter its urgency—it's no longer just a theoretical exercise, but a reflection of how real decisions are made in an increasingly unstable world.

The Making of a Nuclear Drama

Smia's approach to realism is meticulous. He worked with nuclear deterrence expert Bruno Tertrais, whose book Jupiter à l'Élysée helped shape the screenplay. Even more impressively, he was granted access to the Élysée Palace for two days of filming—complete with a crew of 200 people and scenes in the gardens.

The attention to detail goes beyond just set design. The characters are steeped in political jargon, which Smia describes as "almost a foreign language." To prepare, the cast rehearsed together in a chapel for an entire week—a ritual that brought them closer to the psychological weight of their roles.

This is where Jupiter truly stands apart from typical political thrillers. It's not about bombast or sensationalism; it's about the human cost of decisions made in darkness, far from public view.

A Cinematic Chamber Piece

While many nuclear thrillers lean into action and spectacle, Smia opts for a more contained approach—much like Akira Kurosawa's High and Low. The film unfolds almost entirely within the confines of the Jupiter command center, a stark and austere environment that mirrors the gravity of its subject matter.

"How do you infiltrate the nuclear threat into an office 40 meters underground?" Smia asks. "That's a directing challenge I love." The result is a tense, almost claustrophobic experience where the real danger comes not from explosions or gunfire, but from the silence of the decision-making process.

Smia even cites Steven Spielberg's Jaws for its use of off-screen menace—a technique that makes the unseen threat feel all the more terrifying. In Jupiter, the nuclear weapon isn't just a plot device; it's an ever-present force, shaping every conversation, every hesitation.

Shakespearean Tragedy in Politics

What sets Jupiter apart is its portrayal of President Archambault as a tragic figure—not a hero or villain, but a man who must shoulder the burden of ultimate power. Smia likens him to Richard III: "a cursed king in his castle."

"The decision he makes is tragic, impossible, terrible, apocalyptic," Smia says. "At the same time, what fascinates me is that he does it for values he believes in." This emotional complexity elevates the film beyond a simple cautionary tale. It becomes a meditation on leadership, ethics, and the weight of authority.

The Future of Political Cinema

In an age where political cinema often feels like a relic of another time, Jupiter reminds us why it matters so much. Smia is part of a new wave of filmmakers who are unafraid to confront the present moment with honesty and fearlessness.

"The era we're living through means that we filmmakers have to connect ourselves to the contemporary world and look it straight in the eye," he says. Jupiter is not just a film—it's a mirror reflecting the world we live in, one where nuclear weapons loom larger than ever.

As geopolitical tensions rise and global crises unfold, Smia's vision of a French president caught between duty and dread feels more relevant than ever. Jupiter is not just a movie; it's a wake-up call for all of us who believe that art should illuminate truth, even when that truth is terrifying.
