Dark Nuns

If you told me ten years ago that Song Hye-kyo—the undisputed queen of the "K-Drama tearjerker"—would eventually spend two hours in a sweat-drenched basement screaming at ancient demons, I probably would’ve laughed you out of the room. But here we are. I caught a late-night screening of Dark Nuns while nursing a lukewarm peach iced tea that had entirely too much ice, and honestly, the rattling of those cubes against the plastic cup was the only thing keeping my heart rate in check.

As a spiritual successor to the 2015 hit The Priests, this film had a lot of weight on its shoulders. It’s part of "The Priests Collection," a burgeoning cinematic universe that feels like South Korea’s answer to The Conjuring—only with significantly more theological anxiety and better-tailored vestments. While it arguably slipped through the cracks for Western audiences due to a crowded streaming window, it remains one of the most stylishly oppressive horror films of the mid-2020s.

A New Face of Fear

The real draw here is the subversion of the "nun" trope. We aren’t talking about the jump-scare-factory Valak from the Conjuring universe. Song Hye-kyo, playing Sister Giunia, delivers a performance that is all internalised steel. Following her massive success in The Glory, she’s clearly in her "vengeance and grit" era, and it suits her perfectly. She carries a look of perpetual exhaustion that feels lived-in, not just applied by a makeup artist.

Opposite her is Jeon Yeo-been as Sister Michela. If you saw her in Vincenzo or the wildly underrated Glitch, you know she has this uncanny ability to look both terrified and absolutely lethal at the same time. Jeon Yeo-been is the only actor working today who can make a whispered prayer sound like a legitimate physical threat. The chemistry between the two isn’t warm; it’s a bond forged in the desperation of being ignored by a patriarchal church hierarchy that would rather let a child perish than let a woman perform a "forbidden" ritual.

The Craft of the Dark

Director Kwon Hyeok-jae and cinematographer Choi Chan-min (who did incredible work on The Wailing) treat the setting like a character. The film mostly takes place in cramped, suffocating interiors. There’s a specific sequence involving a ritual with Moon Woo-jin, playing the possessed boy Choi Hee-joon, that is genuinely hard to watch. Moon Woo-jin is a child actor who has been in everything from It's Okay to Not Be Okay to Train to Busan Presents: Peninsula, but here he’s asked to do some heavy lifting with practical effects and body contortions that made my own spine ache.

The production team at Zip Cinema opted for a "less is more" approach with the CGI, relying heavily on old-school trickery—shadows that move just a fraction too late and sound design that makes the simple act of a rosary clicking sound like a bone snapping. The score by Kim Tae-seong (who scored the original The Priests) swaps out traditional gothic organs for a more discordant, industrial drone that really gets under your skin.

Why It’s a Hidden Gem

So, why didn't this become a global phenomenon? It was released during a period of massive "exorcism fatigue" in the streaming world. With a dozen Exorcist sequels and spin-offs clogging the pipes, a subtitled Korean drama about nuns felt like a niche ask for the casual viewer. Furthermore, the theatrical distribution was somewhat spotty outside of Asia, leaving it to be "discovered" by horror hounds on boutique streaming services months later.

It’s a shame, because the film tackles some heavy-duty themes about the agency of women within religious structures. Lee Jin-uk, playing Father Paolo, and the legendary Huh Joon-ho (who was terrifying in The Medium) represent the "official" side of the Church, and the friction between their bureaucratic caution and the nuns' proactive sacrilege provides the film’s best dramatic tension. The Catholic Church hasn't looked this bureaucratic and unhelpful since the last time I tried to renew my passport at the post office.

A bit of behind-the-scenes trivia: word is that the production actually consulted with real exorcists to ensure the Latin incantations and ritual steps were "accurate," which allegedly led to some "unexplained" technical glitches on set. Whether that’s just clever marketing or genuine spooky-set syndrome, it adds a layer of grime to the viewing experience that you just don't get with Hollywood's more polished offerings.

Dark Nuns doesn't reinvent the wheel, but it certainly greases it with enough holy water and blood to make it spin faster than you’d expect. It’s a somber, beautifully shot piece of contemporary horror that prioritizes character over cheap thrills. If you’re tired of the same old jump-scares and want a film that feels like a heavy, cold blanket on a winter night, this is the one to track down. It’s a testament to the fact that sometimes, the most terrifying things aren't the demons under the bed, but the lengths we have to go to when the institutions meant to protect us look the other way.
