Sirât (2025) [Altitude UK 4K UHD Review]

Sirât broke me in a movie theater, and now Altitude Film Distribution has given it the chance to break me again at home. The UK 4K UHD release of Oliver Laxe’s Cannes Jury Prize winner arrived on May 25, 2026, and I have been living with this disc for a while now, turning it over in my head the way you turn over a stone in the desert to see what crawls out. Sirât is not a comfortable film. It is not a tidy film. It is a film that invites you to a rave at the edge of the world and then keeps driving past the edge. What Altitude has done here is give one of the most physically overwhelming theatrical experiences of 2025 a home presentation that actually honors the assault. That is rarer than it should be.

The Quick Take

Sirât is a techno-scored death march through the Moroccan desert that turns a missing person drama into something closer to a spiritual ambush, and Altitude’s 4K disc delivers the image and the all-important low end with serious muscle.

Rave New World

Sirât opens with speakers. Not people, speakers. Stacks of them, being bolted together in the rocky moonscape of southern Morocco while a crowd of ravers waits for the sound system to wake up. When it does, Oliver Laxe holds on faces. Sunburned, pierced, scarred, ecstatic faces, most of them belonging to non-professional actors who actually live some version of this free party life. Into this churning mass walks Luis, played by the great Sergi López, a middle-aged Spanish father with a stack of flyers. His daughter Mar vanished months ago somewhere on this circuit of endless desert parties. Luis and his young son Esteban, played by newcomer Bruno Núñez Arjona, move through the crowd handing out her photo to people who can barely focus their eyes.

That setup sounds like the first act of a hundred grim European thrillers, and Sirât knows it. Laxe and co-writer Santiago Fillol use the missing daughter as bait, for Luis and for us. When the Moroccan military shuts the party down and word spreads of one final rave deeper in the desert, near the Mauritanian border, Luis makes the decision any desperate parent makes in these films. He follows. He attaches his van to a convoy of ravers in battered trucks, with their dogs and their amputations and their generosity and their damage, and Sirât drives off the map of the genre it pretended to be.

I want to be careful here, because the film’s reputation precedes it at this point, and the less you know about the back half of Sirât, the harder it hits. What I will say is that the title comes from Islamic tradition, where the Sirât is the bridge over hell that every soul must cross, thinner than a hair and sharper than a sword. Laxe takes that image literally and structurally. The entire film is a crossing. Some people make it. The order in which they fall is the film’s cruelest and most honest idea.

Laxe and Found

Some context helps if Sirât is your introduction to Oliver Laxe, because almost nothing in the modern festival ecosystem prepared audiences for this guy operating at this scale. Laxe is a Galician-born filmmaker raised partly in France who spent years living in Morocco, and every one of his features before Sirât premiered at Cannes and walked away with hardware. You All Are Captains, his 2010 debut, was a meta-documentary made with children in Tangier that took the FIPRESCI prize. Mimosas, in 2016, was a mystical western about a caravan carrying a dying sheikh through the Atlas Mountains, and it won the Critics’ Week grand prize. Fire Will Come, in 2019, brought him home to Galicia for a smoldering portrait of an arsonist returning to his village, and it took the Jury Prize in Un Certain Regard. The man simply does not miss at that festival, and Sirât completing the set with the main competition Jury Prize feels less like a breakthrough than a coronation that was always coming.

What makes the leap interesting is that Sirât is Laxe’s first film with real money behind it. Pedro Almodóvar’s El Deseo came aboard as producer alongside Movistar Plus+, and the budget bought him trucks, pyrotechnics, a soundsystem, and the logistics of moving a crew across some of the least hospitable terrain in North Africa. Plenty of slow cinema poets get handed resources and immediately sand down everything that made them distinctive. Laxe did the opposite. Sirât takes the mysticism of Mimosas, the elemental dread of Fire Will Come, and the documentary porousness of his debut, then sets the whole inheritance on fire at 140 beats per minute. Every theme he has been circling for fifteen years, faith without doctrine, landscapes as spiritual instruments, the dignity of marginal people, converges here. That is why Sirât plays like a culmination even to viewers who walked in cold.

The Almodóvar connection matters in one more way. El Deseo lending its credibility to something this uncommercial gave Sirât a runway most films of its temperament never get. It became a genuine theatrical event in Spain, one of the year’s biggest domestic hits despite its content, and the box office story became part of the film’s legend. A movie this confrontational becoming a national talking point is the kind of thing that restores my faith in audiences, the same faith I felt watching boutique labels turn fringe titles into physical media success stories over the past decade.

Bridge Over Troubled Sand

What separates Sirât from the misery-tourism it could have been is that Laxe genuinely loves these people. The ravers are not props or cautionary tales. Jade, Tonin, Steffi, Josh, and Bigui are played by real figures from the European free party scene, several with visible disabilities, and the camera regards their bodies with the same awe it gives the Atlas Mountains. There is a long sequence early on where the convoy stops and the crew simply exists together, cooking, fixing engines, dancing to a portable speaker, and Sirât briefly becomes the warmest film of 2025 before it becomes one of the most devastating. That whiplash is the point. Laxe builds a family out of strangers specifically so the desert can take it apart.

Sergi López does career-best work as Luis, which is saying something for an actor whose villain in Pan’s Labyrinth remains one of the great screen monsters of the century. Here he is all soft edges, a man whose body language apologizes for taking up space. Watching López slowly absorb the logic of the convoy, ditching his city clothes, learning to read the dunes, is watching a man cross his own internal bridge. The film’s centerpiece for me is not any of its shocks but the moment Luis finally dances. It is graceless and desperate and it plays like prayer, which I am convinced is exactly how Laxe intends it. The director has spoken for years about cinema as a spiritual technology, and Sirât is his most extreme experiment in that direction. He is not interested in whether God exists in this desert. He is interested in what people do when the question stops being theoretical.

The film took the Jury Prize at the 2025 Cannes Film Festival, went on to become Spain’s Oscar submission, and picked up BAFTA and Academy Award attention during the 2026 season, which still amazes me for a film this confrontational. Neon grabbed it for North America, continuing their streak of bottling whatever Cannes is brewing. But the awards conversation almost undersells how feral Sirât is. This is not a polite festival object. It is a film with landmines in it, in every sense.

Bass Instincts

The score and sound design deserve their own section because Sirât is, before anything else, a film about frequencies. French techno producer Kangding Ray built the music from the ground up, and Laxe weaponizes it. The raves are shot from inside the bass, the camera pressed against speaker cones, the sub frequencies treated as a character with motives. When the music stops, and Sirât is brutal about when it stops, the silence of the desert arrives like a verdict.

Mauro Herce’s 16mm cinematography is the other half of the film’s body. Sirât was shot on film in real desert locations, and the grain, dust, and heat shimmer are inseparable from the experience. Herce shoots the trucks like Wages of Fear, which Laxe has openly cited, and the comparison is earned. The convoy sequences across salt flats and mountain passes carry that same sweaty, fatalistic suspense, the sense that the landscape is a casino and everyone is playing with their lives as chips. If Henri-Georges Clouzot had access to a 10,000 watt sound system and a head full of Sufi poetry, he might have made something like Sirât.

The film does have rough edges. A late structural pivot will lose some viewers entirely, and I have heard the complaint that Laxe mistakes endurance for profundity. I do not agree, but I understand the allergy. Sirât asks for a surrender that not everyone will grant, and it punishes attachment in ways that can feel like a dare rather than a design. On a second and third viewing, though, the design is unmistakable. Every loss in this film is foreshadowed, every cruelty is weighed, and the ending, which I will not spoil, recontextualizes the title so completely that I sat through the credits doing theology in my head. Movies do not usually do that to me on a Tuesday.

Esteban’s Eleven (Trucks)

I have not said enough about Bruno Núñez Arjona, and Sirât does not work without him. Esteban is somewhere around twelve years old, dragged into the desert on a search he half understands, and Núñez Arjona gives one of those uncalculated child performances that directors spend careers chasing. He bonds with the ravers faster than his father does, because of course he does. Kids recognize family wherever it actually exists. His scenes with the convoy’s dogs, particularly the scruffy mutt Pipa who becomes the film’s unofficial mascot, are little oases of uncomplicated tenderness that Laxe plants with surgical intent. I have rarely felt a filmmaker manage my attachment so deliberately, and I have rarely resented it less, because the attachment is the argument. Sirât believes love is real precisely because it can be lost, and the film has the nerve to follow that belief all the way down.

The convoy itself deserves to be discussed as a single organism. Laxe found his raver cast in the actual French free party scene, people whose tattoos, missing limbs, and weathered faces carry decades of lived history that no makeup department could fabricate. Jade Oukid is the standout for me, a woman whose hardness reads instantly as armor over enormous warmth, but the ensemble functions like a body with shared blood. There is a scene at a fuel stop where the group debates whether to let Luis and Esteban continue with them, and the negotiation is conducted in half-sentences and glances, the shorthand of people who have survived together. Compare that texture to the labored found-family dialogue in a dozen recent studio films and the gap is humiliating. Sirât gets in two minutes what franchises cannot buy in two hundred million dollars.

And then there is the geography. The film moves from mountain raves to salt flats to a final stretch of mined borderland, and each landscape reshapes the story’s rules. Laxe shot in real locations in southern Morocco, in conditions the making of documentary confirms were nearly as punishing as what the film depicts. The land in Sirât is not a backdrop. It is a character with a theology, indifferent in a way that reads alternately as cruelty and grace depending on where you are standing. By the final movement, when the convoy has thinned and the film commits to its most radical structural gambit, the desert has become the only honest authority left on screen. I keep thinking about how Sirât stages its catastrophes in wide shot, refusing the cut, refusing the score, making the land swallow the event. That restraint is where the film earns the right to its excess everywhere else.

Dust to Dolby Vision

Altitude’s native 4K presentation of Sirât is the kind of disc I want to hand to people who think catalog and arthouse titles get shortchanged on the format. The film occupies nearly the full capacity of a BD-100, with the feature alone consuming around 75 GB at a total bitrate hovering near 87 Mbps. For a 16mm-originated production, that bitrate headroom matters enormously, and you can see exactly where it goes. The grain field is thick, organic, and completely stable, even in the punishing conditions this transfer has to navigate: low-light rave sequences lit by rigs and fire, blinding midday salt flats, dust storms that fill the frame with chaotic fine detail. Cheaper encodes turn this kind of material into smeary soup. Sirât on this disc looks like projected film.

The Dolby Vision grade is where the presentation earns its score. The desert sequences in Sirât run hot by design, with whites that bloom at the edge of pain, and HDR gives that heat a physical presence that the theatrical DCP only hinted at for me. Sun on metal, the white photo of Mar against tanned hands, headlights cutting through blue pre-dawn haze, all of it has range without ever tipping into the artificial. Night scenes hold their shadows beautifully. The first rave is a torture test, strobing colored light against black rock and dark skin, and the disc keeps black levels deep and noise-free while letting the grain dance naturally on top. Skin tones stay earthy and sunblasted throughout, exactly as Herce’s photography intends.

Are there nits? A couple of the optically darkest moments flirt with crush, and viewers allergic to heavy grain should understand that Sirât is a heavy grain film, full stop. The 16mm texture is the aesthetic, and Altitude has wisely left it completely alone. No filtering, no edge enhancement, no digital makeup. This is among the best-looking small-gauge transfers I have covered, sitting comfortably alongside the strongest film-sourced 4K discs in my collection.

Atmos-fear in the Sahara

The Dolby Atmos track on Sirât is the single best reason this disc exists, and I do not say that lightly about a film I just spent two thousand words praising. Kangding Ray’s techno score is mixed here with a low-frequency authority that genuinely rivals demo-grade blockbuster material. The opening rave drops sub-bass into the room that you feel in furniture, in floorboards, in your sternum. My SVS sub got the workout of its year. But what impressed me even more is the discipline of the mix. Sirât is not wall-to-wall noise. The Atmos field spends most of its time on environment: wind moving across the heights, gravel under tires, the metallic groan of overloaded trucks, insects, distant thunder. The desert breathes through the overheads, so when the music returns, or when the film detonates one of its sudden horrors, the dynamic swing is seismic.

Dialogue, a mix of Spanish, French, Arabic, and English, stays clean and properly prioritized in the center channel even when the soundscape goes feral. The optional English SDH subtitles are well-timed and unobtrusive. Altitude has also included a Spanish LPCM 2.0 track, which I sampled out of curiosity and found surprisingly potent in its own right, clearly built for purists or modest setups rather than as an afterthought. But make no mistake, the Atmos mix is how Sirât demands to be heard. Late in the film there is a sound event, and those who have seen it know exactly which one I mean, that this track renders with such tactile force that I involuntarily checked on my dog. That is a 96 out of 100. I am only docking points because the quietest dialogue passages sit a touch low against the dynamic peaks, requiring a volume commitment that apartment dwellers may not be able to make. Honestly, Sirât at apartment volume is barely Sirât at all.

From the Vaults

Here is where the Altitude release of Sirât comes back to earth. The lone substantial extra is a making of documentary covering the Moroccan shoot. It is a worthwhile piece, with footage of the crew wrangling trucks and sound systems through genuinely hostile terrain, and glimpses of Laxe directing his cast of non-professionals with the patience of a man running a commune rather than a film set. Seeing how much of the desert logistics were real, no stage trickery, deepens the film’s already considerable physical credibility. López appears relaxed and reflective, and the raver cast members are charming company.

But that is the whole vault. No commentary from Laxe, whose interviews on the Sirât press tour were some of the most fascinating director talk of the year. No isolated score option for Kangding Ray’s music, which would have been a gift. No Cannes footage, no visual essay, nothing on the film’s theological framework. For a title with this much critical weight and this much to unpack, the supplemental package feels like a missed opportunity, and it is the only thing keeping this release out of the top tier. I would not be shocked if a stacked collector’s edition emerges from a boutique label down the road, Criterion and Sirât feel like an eventual marriage, but the A/V presentation here is so strong that waiting feels like its own punishment.

Import Duty Calls

A practical word for the American readers, since Sirât currently sits in that familiar limbo where the UK disc beats the US market to physical. The Altitude 4K is confirmed region free on the UHD side, so any North American player will spin it without complaint, and the British retail price of £24.99 keeps the import math reasonable even after shipping. Neon handled the North American theatrical run, and history says a domestic disc will materialize eventually, but Neon’s home video timelines wander, and there is no guarantee a future US edition carries this exact transfer, this Atmos mix, or this bitrate generosity. Speaking as someone who has been burned waiting for domestic editions that arrived compromised, I imported, and I am glad I did.

The packaging itself is straightforward Altitude house style, a standard black UHD case with the striking theatrical key art of figures dwarfed by desert, no slipcover on the standard edition, disc art kept simple. The menu is clean and fast. There is also a standalone Blu-ray edition at a lower price point for the 1080p crowd, but given how central image texture and dynamic range are to what Sirât does, I would call the 4K disc the only real choice for anyone with the hardware. This is precisely the kind of film where the format gap is not academic. The grain resolution alone justifies the extra ten pounds, and the Dolby Vision pass is doing legitimate expressive work in the desert sequences, not just adding nits for the spec sheet.

Crossing Over

Sirât is the kind of film physical media exists for. It is too volatile for the algorithm, too patient for a phone screen, and too dependent on image texture and bass pressure to survive a compressed stream with its power intact. Altitude Film Distribution clearly understood the assignment on the technical side, delivering a native 4K Dolby Vision transfer that protects every grain of Mauro Herce’s photography and an Atmos track that belongs in the conversation for the best of 2026. The thin extras sting, but they do not change the verdict. Oliver Laxe made one of the defining films of this decade, a desert crossing that doubles as a crossing of the soul, and this region free disc is currently the definitive way to take that journey at home. Pack water. Check your subwoofer. Say goodbye to whoever you came in with.

Sirât 4K UHD earns a 90/100.
