The Korean zombie genre is about to get a major new addition.
Ever since the first trailer for Colony dropped, fans have been eager to learn more about the film. Directed by Train to Busan filmmaker Yeon Sang-ho and led by an impressive cast that includes Jun Ji-hyun and Ji Chang-wook, the movie has quickly become one of the most anticipated Korean releases of 2026.
Adding to the excitement is the film's unique premise. Rather than following a typical zombie outbreak, Colony introduces a terrifying new threat and traps its characters inside a quarantined building, where survival becomes increasingly difficult.
With international release dates now rolling out and viewers searching for where to watch the movie, here's everything we know so far about Colony!
What Is Colony About?
Colony follows Kwon Se-jeong (Jun Ji-hyun), a biotechnology professor who becomes trapped inside a conference building after a mysterious virus outbreak spreads among attendees.
As authorities seal off the building, the survivors quickly realise they are facing something far more dangerous than a typical infection. The infected continue to evolve, adapt, and become increasingly unpredictable, forcing everyone inside into a desperate fight for survival.
At the centre of the chaos is Se-jeong, who must uncover the truth behind the outbreak while navigating fear, betrayal, and the growing threat surrounding her.
Ji Changwook and Jun Ji-hyun Lead a Star-Studded Cast
One of the biggest reasons behind the excitement surrounding Colony is its cast.
Jun Ji-hyun takes on the role of Kwon Se-jeong, marking her highly anticipated return to the big screen. Joining her is Ji Chang-wook as Choi Hyun-seok, a survivor who becomes entangled in the dangerous events unfolding inside the quarantined building.
The film also features Koo Kyo-hwan, Shin Hyun-been, Kim Shin-rok, and Go Soo, creating one of the strongest ensemble casts seen in a Korean genre film this year.
Why Colony Is Already Being Compared to Train to Busan
Whenever Yeon Sang-ho returns to the zombie genre, comparisons to Train to Busan are inevitable.
However, Colony appears to offer a fresh take on the genre. Rather than focusing solely on fast-moving zombies, the film introduces infected creatures that adapt and evolve as the outbreak spreads.
Early previews suggest that the threat in Colony is not only physical but also psychological, creating a survival thriller that feels both intense and unpredictable.
For fans of Train to Busan, Kingdom, and All of Us Are Dead, this is easily one of the most anticipated Korean zombie movies of 2026.
Colony Trailer: What to Expect
The official trailer offers a glimpse into the film's claustrophobic setting, high-stakes action, and terrifying infected creatures.
Viewers can expect large-scale survival sequences, emotional character moments, and the signature tension Yeon Sang-ho is known for. The trailer also highlights the growing desperation among the survivors as the infection continues to evolve.
The combination of horror, suspense, and action has already generated significant buzz among both Korean and international audiences.

After making its world premiere at the Cannes Film Festival, Colony officially opened in South Korean theaters on May 21, 2026.
The film's strong festival reception and global distribution deals have helped it become one of the most talked-about Korean films of the year.
