Yeon Sang-ho is heading back into zombie territory with the new film Colony, and a new trailer just released.
If that name sounds familiar, it’s because he’s the director behind Train to Busan. And while Colony isn’t a sequel, the timing lines up in an interesting way. Train to Busan is also coming back to theaters in 4K for its 10th anniversary.
So yeah, it’s a good time to be a zombie fan.
The setup is pretty straightforward, but it works.
Colony takes place during a biotech conference where something goes wrong fast. A virus breaks out inside the facility, and instead of letting it spread, authorities lock the entire place down. Which means everyone inside is stuck.
From the trailer, most of the story looks like it stays inside that space. You’ve got people trying to figure out what’s happening while things get worse around them. There’s panic, confusion, and that feeling that nobody really knows how bad it’s about to get.
The infected also don’t seem completely predictable. There are hints that whatever this virus is, it might be changing as it spreads. The trailer doesn’t spell it out, but it’s enough to raise some questions. And honestly, that’s probably the point.
‘Train to Busan‘ Is Coming Back to Theaters
At the same time, Train to Busan is getting a 4K theatrical re-release in the U.S. for its 10th anniversary.
If you’ve never seen it in a theater, this is one of those movies that really benefits from it. The tight spaces, the pacing, the way everything keeps moving, it hits differently on a big screen. And if you’ve already seen it, you probably know why people are excited to go back.
If you want to own the 4K DVD of Train to Busan you can pick that up here.

Bringing Train to Busan back right before Colony comes out feels pretty intentional.
It puts Yeon Sang-ho back in front of audiences and reminds people what kind of stories he tells, without needing a direct connection between the two films.
They’re separate projects, but they definitely sit in the same space.
Yeon Sang-ho Back in Familiar Territory
Yeon Sang-ho has done a mix of projects since Train to Busan, but Colony brings him back to a type of story people already associate with his work. Not in a sequel way, just in tone and setup. It’s another situation where people are thrown into something they don’t understand and have to react in real time.
Between Colony and the return of Train to Busan, there’s a bit of a spotlight back on Yeon Sang-ho and the kind of zombie stories he tells. One is something familiar coming back to theaters. The other is a new story that’s just getting started. We’ll see how much more gets revealed soon, but for now, the trailer at least gives a solid idea of what kind of ride Colony is setting up.
