What La chaleur is about
La chaleur centers on Marouane, a 17-year-old whose last day at a Landes campground should feel like any other slow August afternoon — except it isn't. The beach is baking under an abnormal heatwave, the kind that warps your thinking, and Marouane is carrying something far heavier than sunburn: the knowledge that he buried a body in the sand the day before. As described on AlloCiné, the film holds him in that unbearable in-between space — waiting to be caught, waiting to feel something other than dread — while a girl named Giulia keeps pulling his attention toward something that looks dangerously like hope. The premise is deceptively simple. One day. One secret. One summer.
How La chaleur came together — cast, source material, and release
Director Stéphane Demoustier adapted La chaleur from Victor Jestin's acclaimed 2019 French novel of the same name, and the source material's psychological claustrophobia translates almost uncomfortably well to the screen. Demoustier, who previously directed the taut legal drama La fille au bracelet (2019), has a demonstrated instinct for putting young people under pressure and watching what cracks — so this project feels like a natural, almost inevitable, next step for him.
The film stars Hadrien Hussein as Marouane, a relatively fresh face carrying the entire film on his shoulders for most of its 93-minute runtime. Tristan Richard, Martina La Manna, and Noé Houssard round out the key roles, with La Manna playing Giulia. Production involved a notably collaborative international setup: Petit Film led the project, with partners including Panache Productions, La Compagnie Cinématographique, Wildside, and The Dreaming Sheep Company — a French-Italian-Belgian co-production that gave the film a broader European footprint than most festival-circuit thrillers manage.
The film premiered at the Biarritz Nouvelles Vagues festival before its French theatrical release on 8 July 2026. Hard to say if the Biarritz premiere was a strategic choice or just logistically convenient, but either way, launching a film about the Landes coast at a festival rooted in Atlantic France feels exactly right. As tracked on Letterboxd, early audience activity is building. Detailed critic aggregates and box-office figures haven't been published yet at the time of writing, but Pathé's user sample skews positive — more viewers marking it "adoré" than "déçus," which is an encouraging early signal.
The performances and craft that make La chaleur worth watching
What's striking is how much of this film lives in Hadrien Hussein's face. There's a scene early on — Marouane standing at the shoreline, watching other campers laugh and splash in the shallows — where Hussein communicates something like vertigo without saying a word. The gap between his internal reality and the mundane holiday noise around him is where the film does most of its real work. That tension, sustained across a single day's running time, is genuinely hard to pull off.
Demoustier shoots the Landes beaches with a kind of hostile beauty — the heat isn't just weather here, it's atmosphere, pressure, almost a character in its own right. The promotional materials describe the film as "fiévreux et captivant," and that's not marketing language for once. It actually is feverish. The editing keeps things close and slightly airless, refusing to give the audience the wide establishing shots that might offer relief.
The romance thread with Giulia (Martina La Manna, warm and specific in a role that could easily have been decorative) complicates the thriller mechanics in genuinely interesting ways. Marouane's attraction to her isn't escapism exactly — it's more like the one thing reminding him he's still a person. That contradiction, between guilt and desire, between wanting to disappear and wanting to be seen, is where Jestin's novel was sharpest, and Demoustier preserves it.

Final thoughts on La chaleur — who should watch it
La chaleur is not a comfortable film. It doesn't want to be. If you're drawn to tightly wound European thrillers that trust their audience to sit with discomfort — films like Raw or The Swimmer — this one belongs on your list. Demoustier keeps the screws turning for the full 93 minutes without ever tipping into melodrama. Fans of Jestin's source novel will find it a faithful, visually confident translation. And anyone who spent a summer holiday feeling like they were living inside their own head will recognize something true in Marouane's suffocating afternoon. Movie OTT recommends it without hesitation.
