Yeon Sang-ho is working on a new zombie movie through which he can finally redeem the underwhelming sequel toTrain to Busan. The zombie genre is full of hits and misses both in film and TV, but in 2016, Yeon Sang-ho brought one of the biggest successes of the genre withTrain to Busan. The film was a critical and commercial success, spawning a movie series with a prequel, a sequel, and an American remake that is currently trapped in development hell.

Train to Busanfollows Seok-woo (Gong Yoo), a workaholic and divorced father taking his estranged daughter, Su-an (Kim Su-an), to Busan so she can spend her birthday with her.Once on the train, they learn about the sudden break of a zombie apocalypse, and, unfortunately, one of the passengers is infected. What follows is the rest of the passengers’ desperate efforts to survive and get to Busan, the closest safe zone. Now, five years afterTrain to Busan’s sequel,Peninsula,Yeon Sang-ho is working on a new zombie movie,Gunche, which won’t be a stranger from the world ofTrain to Busan.

Gunche Is A New Addition To The Train To Busan Universe

The last entry in theTrain to Busanuniverse was the sequelPeninsula, in 2020, and since then, Yeon Sang-ho has moved on to other projects. Yeon has one movie,Revelations, released in 2025, and he’s now working on another zombie movie that’s taking him back to the world ofTrain to Busan. In March 2025, it was reported that Yeon’s next project isGunche, with Jun Ji-hyun, Ji Chang-wook, and Koo Kyo-hwan already signed to be part of the cast. At the time of writing, there’s no word on whatGunche’s English title will be.

“Gunche” in Korean means colony in a biological context.

The announcement includes the confirmation ofGunchebeing part of theTrain to Busansaga, with distributor Showbox describing the project as the “culmination” of Yeon’s universe that began withTrain to Busanand continued withPeninsula. However,it’s unclear if Gunche is a direct sequel toTrain to Busan,Peninsula, or evenSeoul Station, in which case it would be set between this andTrain to Busan.Gunchecould also be a standalone sequel, meaning it would expand this universe without continuing where the previous movies left off.
