Bury the Devil (2026) - Adam O'Brien Horror Film

The first thing you notice about Bury the Devil is how small it is. Not in ambition - but in the sheer, suffocating geography of its terror. Director Adam O’Brien has crafted an 84-minute nightmare that barely leaves a single house, and yet, by the time the credits roll, you feel like you’ve traversed the raw edges of hell. It’s a masterclass in claustrophobic horror, released into theaters on March 6, 2026, and it’s still burrowing under your skin months later.

The setup is deceptively simple. Julia, played with a brittle, fraying intensity by Emmanuelle Lussier Martinez, is a hospice nurse assigned to a night shift at the remote home of Evelyn (Dawn Ford), an elderly woman suffering from advanced dementia. What begins as a routine vigil - administering meds, soothing restless murmurs - quickly curdles into something far more sinister. Evelyn isn’t just confused. She’s wrong. Her mutterings shift into languages Julia doesn’t recognize. The temperature in the room drops without warning. And those eyes - Ford’s performance is a slow, guttural unraveling - suggest someone, or something, is looking back through the fog of a failing mind.

What makes Bury the Devil so effective is how O’Brien refuses to let the audience off the hook with a simple “it’s all in her head” or a jump-scare cheat code. The film walks a razor-thin line between psychological realism and supernatural dread. Is Julia, exhausted and isolated, projecting her own trauma onto a dying woman? Or is there genuinely a malevolent presence clinging to Evelyn’s last lucid moments? The script doesn’t spoon-feed you. Instead, it lets the house itself become a character - creaking floorboards, flickering lightbulbs, and a crucifix that seems to rot in slow motion.

Lussier Martinez anchors the film with a performance that feels like a nerve exposed. Her Julia is pragmatic, weary, but fiercely compassionate - until fear corrodes that compassion. You watch her professional armor crack, piece by piece, as she realizes that the threat isn’t just to Evelyn’s body but to her own soul. There’s a particular scene, roughly midway through, where she tries to call her supervisor for advice, and the phone line crackles with a voice that isn’t the operator’s. It’s a small, quiet moment, but O’Brien shoots it with such lingering dread that you’ll want to check your own signal afterward.

The supporting cast does heavy lifting with minimal screen time. Bill Rowat appears as Randall, Evelyn’s gruff but nervous son, whose brief visit early on plants seeds of unresolved guilt. And Mark Antony Krupa delivers a chilling cameo as Father Thierry, a priest who arrives for last rites but refuses to step past the threshold. He delivers the film’s thematic thesis with a whispered warning: “You don’t bury the devil. You starve it.” That line hangs over the entire runtime like a guillotine blade.

O’Brien, known for his lean, mean approach to genre filmmaking, clearly studied the playbook of early Polanski and late-period Kiyoshi Kurosawa. He uses long takes and ambient sound - wind against the window, the hiss of an old radiator - to build a constant, low-level hum of anxiety. There are no cheap orchestral stings; the horror here is organic, earned through patience. At 84 minutes, it’s ruthlessly tight. Not a single scene overstays its welcome, and the final act, when the film shifts into more visceral, body-horror terrain, is a gut-punch that pays off every subtle clue laid before.

The film’s TMDb rating of 6.5 out of 10 feels almost unfairly modest, a number that suggests a capable thriller but undersells its staying power. This is a movie that rewards a second watch - you’ll catch details you missed, like the way Evelyn’s fingers count invisible beads, or how Julia’s reflection sometimes lags half a second behind her. It’s the kind of horror that doesn’t just scare you in the moment; it lingers in the quiet of your own home, making you double-check the locks.

Is Bury the Devil for everyone? No. It’s slow-burn, moody, and unapologetically ambiguous about its metaphysics. But for viewers who crave horror that trusts their intelligence and respects their patience, it’s a hidden gem from 2026 that deserves a cult following. O’Brien has crafted a film where the scariest thing isn’t the monster in the room - it’s the unshakable feeling that the monster is already inside you, waiting for the lights to go out. By the time Julia fights for her final breath, you’ll understand why the title isn’t a promise. It’s a warning.
