French Thriller Jupiter Premieres at Venice Film Festival Exploring Nuclear War

The plot of Jupiter unfolds after Russia detonates a nuclear warhead over the Black Sea to avenge an assassination attempt against the Russian president. While Germany and Italy urge restraint and the American president opts out of the standoff altogether—even suggesting the elimination of Ukraine’s leader to appease Moscow—the burden of confronting the Kremlin falls squarely on France.

Nuclear Standoff and French Leadership on the Lido

Director Alexandre Smia pointed out that the narrative reflects genuine anxieties regarding European security.

Because France stands as the sole European nation holding membership in the European community, the United Nations Security Council, and Nato, Smia’s script places the weight of continental deterrence on Paris. Filling the void when faced by a threat is not even a choice any more, it becomes almost an obligation, the filmmaker added.

Denis Ménochet and the Weight of the Presidency

At the center of the crisis is the fictional French president Paul Archambault, portrayed by French actor Denis Ménochet. Archambault must navigate tense psychological warfare inside the command bunker beneath the Palais d’Élysée, supported only by the British prime minister. Smia specifically selected Ménochet because his physical appearance does not mirror any actual former French president, distancing the character from real-world political figures.

To establish credibility with the film’s Putin-equivalent character—who taunts Archambault with personal insults and blames western decadence for the loss of the French president’s daughter—Archambault embraces Richard Nixon’s madman theory. The strategy requires projecting irrationality to make extreme threats appear believable, a dangerous gamble that risks inciting public outrage and alienating European allies.

Would any European leader be able to play the madman? The theory of the madman is indeed dangerous and I don’t think that any European leader would do that.

Presidential Echoes and Political Divisions in France

The film carries multiple historical layers within its production design and character development. The title itself nods to the bunker’s command room, which was named after the Roman king of the gods under Valéry Giscard d’Estaing, while also evoking the “Jupiterian” presidency style of Emmanuel Macron and the press nickname once given to François Mitterrand. Furthermore, Archambault’s grief over his deceased daughter mirrors the personal histories of Charles de Gaulle and Jacques Chirac.

During their research phase, the filmmakers consulted with socialist ex-president François Hollande. Yet despite its focus on French resolve, the film deliberately avoids painting a heroic picture of effortless leadership, leaving open the question of whether France is truly equipped for the burden.

Venice Debates and the November Release Schedule

Ahead of its scheduled theatrical release in France in November, Jupiter has already sparked sharp political controversy. Following the drop of the trailer, far-right critics attempted to frame the movie as a propaganda piece designed to bolster support for a centrist candidate against Marine Le Pen’s National Rally in the presidential elections set for next April.

On the Lido, French journalists actively debated whether the thriller serves as an endorsement of aggressive French military posture or a stark warning against it. This deliberate ambiguity places the film alongside recent French conversational cinema like Justine Triet’s Anatomy of a Fall and Cédric Kahn’s The Goldman Case—the latter of whom takes on a supporting acting role in Jupiter—prioritizing verbal sparring and moral grey areas over conventional plot twists.
