Jun Ji-hyun, Koo Kyo-hwan, Ji Chang-wook ‘Gunchai’ Trailer Released… Yeon Sang-ho Creates a New Disaster

Director Yeon Sang-ho's new film 〈Gunchai〉 has officially confirmed its release in 2026 and has dramatically unveiled a captivating 30-second trailer. Following works like 〈Train to Busan〉, 〈Peninsula〉, and the series 〈Hell〉, director Yeon has garnered attention in the film industry for building a unique 'Yeoniverse'.

The film 〈Gunchai〉 depicts the story of isolated survivors trapped inside a building due to an unidentified infection outbreak, battling against infected individuals that evolve in unpredictable ways. Notably, this work marks the return of actress Jun Ji-hyun to the screen after approximately 11 years since the film 〈Assassination〉, featuring a star-studded cast including Koo Kyo-hwan, Ji Chang-wook, Shin Hyun-bin, Kim Shin-rok, and Ko Soo, heightening expectations.

Six individuals' diverse struggles in an isolated building

The released trailer begins with a significant line from biologist Kwon Se-jeong (Jun Ji-hyun), instantly raising the tension. The key character of the incident, Seo Young-cheol (Koo Kyo-hwan), amplifies the mystery with a questioning expression, while building security officer Choi Hyun-seok (Ji Chang-wook) hints at intense action by throwing himself against the infected.

Additionally, Gong Seol-hee (Shin Hyun-bin) is shown struggling to resolve the situation, while Choi Hyun-hee (Kim Shin-rok) reveals tension in a life-or-death crisis, and Han Gyu-seong (Ko Soo) displays a fearful expression amidst chaos, capturing the characters facing disaster in impactful moments within the short video.

Anticipated blockbuster of 2026

The film 〈Gunchai〉 is expected to deliver the unique genre thrill characteristic of director Yeon Sang-ho through the psychological pressure of a confined space and the differentiated setting of 'evolving infected individuals', which sets it apart from existing zombie films. The trailer, which has already generated explosive interest with its pre-release in theaters at the end of the year, has once again solidified its presence as the most anticipated film of 2026.

With overwhelming scale, a solid narrative, and the passionate performances of trusted actors, 〈Gunchai〉 is set to officially release in theaters nationwide in 2026.
