The zombies got a group chat. And somehow, that’s the most unsettling upgrade the genre has seen in years.
I watched Colony (군체 / Gunche) in a theater in Asia a couple months before it hits US screens. No spoilers. Just the take of someone who didn’t expect to be this entertained.
Quick setup: Yeon Sang-ho is back. You know him from Train to Busan — the film that basically reset the global expectation for what a zombie movie could be. After Peninsula (which was… fine, let’s say fine), he’s back with something that feels like he actually wanted to make a movie again, not just cash a sequel check. Colony premiered at Cannes 2026 in the Midnight Screenings slot, dropped in South Korea on May 21, and arrives in the US this August. At a $12M budget and already clearing $25M at the box office, it’s a win before it even hits an American theater near you.
Here’s the pitch Variety gave it: “entertaining if empty-headed.” I’d push back on the second half of that. The “empty-headed” criticism feels like it was written by someone who wanted a slow-burn character drama and was annoyed they got a propulsive action movie instead. That’s a fair preference. It’s not a fair critique of the film on its own terms.
Because the actual premise of Colony is legitimately interesting.
The infection isn’t supernatural. It’s a mutated slime mold bioweapon — engineered, released deliberately, and biological in the most unsettling way. The infected in this film aren’t just shambling bodies. They evolve. They connect. They coordinate. They behave like a colony — hence the title.
If you’ve played The Last of Us, you know the cordyceps concept. What Colony does differently is take the hive-mind angle from background lore to active threat. The infected aren’t just enemies — they’re a distributed intelligence learning in real time. That shift changes the calculus of every action sequence. You’re not just outrunning them; they’re adapting to you. It’s subtle, but it makes the tension feel different. More systemic. More paranoid.
The pacing is closer to World War Z than TLOU. This is an action-forward film. It moves. If you sat through the first three episodes of The Last of Us waiting for the mushroom stuff to get scary, this is the opposite experience. It earns its Cannes Midnight Screenings slot — by the time you’ve caught your breath from one sequence, the next one has already started.
The cast is stacked: Jun Ji-hyun (Gianna Jun), Koo Kyo-hwan, Ji Chang-wook, Go Soo. And look — you’re going to know exactly who everyone is within the first fifteen minutes. There’s the competent hero. There’s the character you want to survive and who probably won’t. There’s the person who makes every situation worse because they panic. There’s someone running on pure revenge energy who will absolutely cause a problem later. There’s a dead professor whose research becomes inconveniently relevant. Colony is not trying to subvert archetypes. It’s working with them because they work, and the cast is good enough to make you care even when you can already see the shape of the plot.
Is the story predictable? Mostly, yes. But predictable isn’t the same as not fun. The villain has a story mechanic that forces the heroes into an impossible bind I won’t spoil. The setting is a massive shopping mall and convention center complex — which is either a George Romero nod or just the most Korean location possible. Probably both.
My take: this is a genuinely good time at the movies. Not transcendent cinema. Not trying to be. It’s a tight, well-paced, visually impressive Korean blockbuster with a concept that’s smarter than it gets credit for, executed by a director who knows exactly how to stage a crowd going wrong. Jun Ji-hyun anchors the whole thing with the kind of controlled intensity she’s been delivering since My Love from the Star.
If you’re in the Bay Area in August looking for something to watch that isn’t a sequel to a sequel to a reboot — Colony is the call.
It opened at Cannes. It’s making money. The infected are getting smarter.
Go watch it before they figure out where you live.
Colony (군체) — directed by Yeon Sang-ho. US release: August 28, 2026.
