What Is Colony About?

Colony follows the story that unfolds as a building is blockaded due to an unknown virus, as those infected evolve into unpredictable forms, threatening the survivors.

But here’s what sets it apart from every other outbreak story — the protagonist isn’t trying to stop the virus. He might be its biggest advocate.

Seo Young Cheol is a genius biologist who once worked for a biotech company and dreams of creating a new humanity. He claims to have a vaccine and becomes a target of both authorities and survivors. TechRadar

A man calmly walking among the infected with empty, detached eyes — that image alone is deeply unsettling.

Why Koo Kyo Hwan Was the Only Choice

Director Yeon Sang Ho stated they needed an actor who could play a character with extraordinary thoughts, different from ordinary people — and Koo Kyo Hwan naturally came to mind. He described it as an extraordinary actor giving an extraordinary performance to bring this new character to life.

Koo Kyo Hwan himself shared that the concepts — different from the usual zombie genre — were what drew him in, saying that if it’s a good project, he wants to be part of it no matter the role.

That kind of mutual creative trust between director and actor is exactly what produces something special.

A Director Who Redefined Korean Horror

Yeon Sang Ho didn’t just make a successful zombie film with Train to Busan — he changed what Korean cinema could do internationally. Colony looks set to push that boundary even further, this time asking a provocative question: what if evolution, not survival, is the point?
