The Great Arch

Imagine a world where the most powerful man in France decides to leave a mark so massive it can be seen from the moon, only to hand the keys to the kingdom to a guy who mostly builds small-town churches in Denmark. In 1983, François Mitterrand wasn’t just the President; he was a monarch in a suit, and his "Grands Projets" were meant to be his eternal legacy. Stéphane Demoustier’s The Great Arch (2025) takes this specific, high-stakes moment in architectural history and turns it into a surprisingly tense, deeply human tug-of-war between visionary purity and political sludge.

I watched this on a Tuesday night while trying to fix a leaking faucet with a wrench that was clearly the wrong size, and something about Johan Otto von Spreckelsen’s struggle to keep his "Open Cube" from being ruined by bureaucrats made my plumbing disaster feel oddly noble.

The Architect Who Came in from the Cold

At the center of the storm is Claes Bang, an actor who seems to have been grown in a lab specifically to play men who are simultaneously imposing and incredibly fragile. As Johan Otto von Spreckelsen, Bang (whom you’ll know from the satirical bite of The Square) portrays a man who is utterly unprepared for the shark tank of Parisian politics. He’s an architecture teacher from Copenhagen who had only built four things in his life—his own house and three chapels. Suddenly, he’s the winner of the biggest competition in history.

Bang plays Spreckelsen not as a triumphant genius, but as a man who is constantly one minor inconvenience away from retreating back to his forest. His chemistry with Sidse Babett Knudsen (the powerhouse from Borgen), who plays his wife Liv, provides the film’s emotional spine. While Johan is dreaming of white Carrara marble and "humanity’s window to the world," Liv is the one reminding him that the French government is essentially a pack of wolves in expensive scarves. Their relationship feels lived-in and weary, a sharp contrast to the cold, geometric perfection of the drawings they’re fighting for.

A Masterclass in Ego Management

The film thrives on the friction between the Danish "less is more" philosophy and the French "more is never enough" attitude. Michel Fau is absolutely delicious as François Mitterrand. He doesn't go for a caricature; instead, he captures that specific, terrifying stillness of a man who knows he can end a career with a single arched eyebrow. Watching him interact with Bang is like watching a cat decide whether to play with a mouse or just swallow it whole.

Then there’s Xavier Dolan as Jean-Louis Subilon. Dolan, usually found behind the camera directing gems like Mommy, turns in a jittery, fascinating performance as the intermediary trying to bridge the gap between the architect’s soul and the President’s demands. He’s the guy caught in the middle, and his frantic energy drives the second act. Swann Arlaud, who was so hauntingly good in Anatomy of a Fall, appears as Paul Andreu, the man who eventually had to help Spreckelsen actually build the thing. Their relationship starts as professional rivalry and morphs into a begrudging, shared burden.

Why It Matters Now

In an era of streaming-service bloat where every movie feels like it was designed by a committee to offend the fewest people possible, The Great Arch feels like a bit of a throwback. It’s a drama about process. It’s about how hard it is to actually make something beautiful when everyone around you wants to make it "functional" or "cost-effective." Demoustier, who previously showed his knack for clinical tension in The Girl with a Bracelet, uses the cinematography of David Chambille to make the blueprints look like holy relics and the scaffolding of La Défense look like a cathedral in progress.

The film is a middle finger to the 'move fast and break things' tech-bro aesthetic that dominates our current cultural landscape. It argues that some things—like a massive hole in the sky in the middle of Paris—require a level of stubbornness that borders on the pathological. In our current moment of "franchise fatigue" and "IP-driven decisions," there is something deeply cathartic about watching a Danish man refuse to compromise on the type of stone he uses for a building he knows might eventually kill him.

The film does occasionally get bogged down in the weeds of French administrative law—which, let’s be honest, is about as exciting as watching paint dry on a government-mandated wall—but it always snaps back to life when Bang and Fau are in a room together. It’s a beautifully shot, superbly acted look at the cost of creation. It reminds me that behind every landmark we take for granted, there was likely a very stressed-out Dane wondering why he didn’t just stay at home and build another chapel. It’s a smart, adult drama that doesn’t feel the need to explode anything to keep your attention.

The Great Arch isn't just about a building; it’s about the terrifying realization that once you win the prize you’ve wanted your whole life, the real nightmare actually begins. If you’ve ever had a vision that got watered down by a "team" of "collaborators," this movie will feel like a documentary. Catch it on the big screen if you can—the scale of the architecture deserves the height of the frame.
