Jupiter

With Jupiter, director Alexandre Smia delivers an ambitious debut feature film, transforming the terrifying prospect of a nuclear conflict into an intimate and psychologically harrowing exploration of political responsibility. At a time when international tensions are reigniting fears once associated with the Cold War, this remarkably intense thriller feels less like speculative fiction and more like a disturbing reflection of our increasingly unstable geopolitical landscape. Co-written with Thomas Finkielkraut, the film eschews the spectacular destruction traditionally associated with apocalyptic cinema, choosing instead to explore the moments leading up to an irreversible decision. At the heart of the plot is actor Denis Ménochet, who delivers a performance that is both commanding and deeply vulnerable as Paul Archambault, the newly elected French president, suddenly confronted with the possibility of triggering a global catastrophe. What makes the film Jupiter particularly unsettling is its refusal to portray political power as a reassuring instrument of control. Here, authority becomes an unbearable responsibility, and the individual supposed to hold the greatest power discovers just how powerless he can become when history accelerates beyond any ability to contain it.

The story begins just as Archambault has taken office as president, with an international crisis threatening to engulf Europe. Following an assassination attempt on the Russian president, Moscow accuses Ukraine of involvement, thereby destabilizing an already fragile diplomatic situation and raising the specter of a nuclear retaliation. Faced with uncertain alliances, stalled negotiations, and military advisors issuing increasingly contradictory recommendations, the French president finds himself forced to consider decisions that no democratic leader should ever wish to make. The story unfolds in the presidential corridors, secure meeting rooms, and the underground command center known as Jupiter, located beneath the Élysée Palace. Rather than building suspense through military operations or scenes of devastation, Alexandre Smia focuses on diplomatic conversations, classified briefings, and the increasingly desperate exchanges between political leaders. Every phone call has the potential to shift the balance of power, every new piece of information introduces further uncertainty, and every attempt at compromise threatens to lead to consequences more dangerous than the last. The result is an unusually intellectual thriller, in which language itself becomes a weapon, and where the difference between restraint and catastrophe may hinge on a single misunderstood intention.

Much of the film’s emotional power comes from the remarkable performance by actor Denis Ménochet, whose imposing physical presence contrasts beautifully with his character’s growing fragility. Audiences familiar with his performances in Inglourious Basterds and Les Bêtes already know of his remarkable ability to convey conflicting emotions without relying on excessive dialogue, but Jupiter presents him with a particularly demanding challenge. His character is neither a heroic statesman in the conventional sense nor an incompetent politician overwhelmed by circumstances. He is an intelligent, deeply human individual who is trying to hold onto his moral convictions while facing a situation where every possible solution carries unacceptable consequences. Personal grief further complicates his judgment, introducing an intimate tragedy at the heart of an already overwhelming political crisis. The moments when Archambault distances himself from his advisors—wandering through the presidential residence or struggling to keep his composure after yet another unsettling conversation—are particularly revealing. His physical unease becomes increasingly visible, as if the presidential role itself were gradually transforming into a tool of confinement. Actor Denis Ménochet never needs an explosive monologue to convey his character’s despair. A hesitation, a prolonged silence, or a barely perceptible shift in expression often speaks louder than an entire political speech.

The supporting cast reinforces the film’s central conflict by embodying different interpretations of national responsibility and strategic necessity. André Dussollier (impeccable) brings authority and experience to the military establishment, while Reda Kateb brings a commanding presence to the increasingly heated discussions surrounding France’s potential response. Céline Sallette, Dominique Blanc, Ella Rumpf, Frédéric Pierrot, Cédric Kahn, and Jérémy Lopez round out an impressive cast whose characters collectively embody the contradictions of political decision-making under extreme pressure. Their disagreements are not merely intended to distinguish the heroes from the villains. Some advocate for diplomacy as the only morally acceptable solution, while others argue that hesitation could encourage further aggression and, ultimately, lead to even greater devastation. This ambiguity is one of the most interesting aspects of the screenplay. The film recognizes that nuclear deterrence rests on a paradox: weapons intended never to be used must nonetheless remain credible enough to deter an adversary from crossing the ultimate threshold. However, the supporting characters sometimes function more as representatives of rival doctrines than as fully realized individuals. Their arguments are intellectually compelling, but the screenplay rarely allows their personal convictions to evolve in any meaningful way, leaving Archambault as the only character whose inner transformation receives sustained attention.

Visually, the film Jupiter demonstrates how a seemingly restrictive frame can become an extraordinarily effective dramatic tool. Director of photography Nicolas Loir gradually compresses the visual space, shifting from institutional compositions to increasingly oppressive close-ups that leave the characters virtually no room to escape the frame. The sumptuous architecture of the French presidency gradually gives way to sterile interiors, subdued lighting, and an atmosphere of near-physical suffocation. Editor Pierre Deschamps maintains a relentless pace, ensuring that every diplomatic setback or strategic disagreement intensifies the sense of impending disaster. At the same time, the soundtrack composed by Olivier Marguerit introduces an unsettling undercurrent that heightens the psychological pressure without resorting to conventional action sequences. There is something particularly effective about seeing decisions that could bring an end to civilization being discussed around ordinary conference tables, accompanied by the familiar sounds of ringing phones and hurried conversations. This contrast between the banality of administrative procedures and the unimaginable scale of their consequences evokes the tradition of political thrillers such as Sidney Lumet’s Fail Safe. At times, however, the emphasis on claustrophobic framing and sustained musical tension becomes slightly excessive, as if the film were hesitant to trust the already terrifying implications of its own premise.

One of the most fascinating aspects of the film is its distinctly French perspective on nuclear deterrence. Unlike American productions, which often emphasize vast military infrastructures and competing chains of command, Jupiter explores a political system in which the ultimate nuclear decision rests with the president. The command center itself is not merely a fictional creation for the sake of the plot: the real Jupiter Command Center does indeed exist beneath the Élysée Palace, and its secrecy has contributed to its almost mythical reputation. During the film’s presentation at the Venice Film Festival in 2026, Alexandre Smia explained that his intention, in collaboration with Thomas Finkielkraut, was to approach this extraordinary responsibility with the utmost realism. 

This ambition also builds on the director’s previous experience as a screenwriter on The Bureau, where intelligence operations and international diplomacy were treated with comparable seriousness. The historical irony surrounding France’s strategic independence—traditionally associated with Charles de Gaulle—is particularly striking: a doctrine designed to guarantee national sovereignty becomes, in this fictional crisis, the source of an almost unbearable isolation. The film is also being released in the shadow of Kathryn Bigelow’s A House of Dynamite, which premiered in Venice the previous year. While that American thriller explores the inner workings of a nuclear emergency, Jupiter focuses on the moral isolation of the person who must, as a last resort, make the decision. Its French perspective lends this familiar cinematic nightmare a distinct political dimension.

However, the film’s emphasis on urgency also accounts for some of its limitations. Its short runtime of 87 minutes leaves little room to explore the ideological contexts of its political characters or the broader consequences—for the civilian population—of the looming disaster. The president’s personal suffering provides a necessary emotional counterpoint, but certain aspects of his family tragedy remain underdeveloped to reach their full dramatic potential. Similarly, the relentless succession of warnings, negotiations, and strategic disagreements sometimes creates a repetitive rhythm, with characters reverting to positions they’ve already firmly established. The conclusion may also frustrate viewers expecting a conventional resolution, although its refusal to offer easy comfort is consistent with the film’s underlying philosophy. Nevertheless, these reservations do not detract from the considerable success of Alexandre Smia, whose debut feature film demonstrates an impressive mastery of dramatic economy. Presented out of competition at the 83rd Venice International Film Festival, the film Jupiter proves that a politically ambitious French production can tackle issues of global significance without sacrificing its identity in favor of Hollywood-style spectacle.  Its greatest achievement is creating the impression that the unimaginable is terrifyingly close—not through images of destruction, but through the terrifying possibility that a catastrophe could result from decisions made by intelligent people who are sincerely convinced that they are thereby preventing something even worse.

"Jupiter" stands out as both a gripping political thriller and a deeply unsettling reflection on the limits of human judgment. Alexandre Smia understands that the most disturbing aspect of nuclear war does not necessarily lie in the destructive power of the weapons themselves, but in the fragility of the psychological and political mechanisms meant to prevent their use. Drawing on precise technical mastery, an impressive cast, and an exceptional performance by Denis Ménochet in the lead role, the film transforms presidential authority into a profoundly tragic condition. Its occasional narrative rigidity and underdeveloped supporting characters prevent it from reaching the complexity of the best political dramas, but its emotional intensity and contemporary relevance make it difficult to dismiss out of hand. What lingers after the credits roll is not the memory of spectacular action, but the image of an exhausted man faced with a decision whose consequences could extend far beyond his country, his presidency, or even his own life. In a cinematic landscape increasingly dominated by extravagant depictions of global catastrophes, Jupiter offers something arguably more unsettling: the realization that the end of the world could begin in an ordinary conference room, with a handful of people discussing options for which there are no acceptable answers.
