The Red Wolf teaser for Park Bo-gum in Kal: Godumakhanui Geom was released on May 7, 2026, giving the first global look at the actor as Chilsung in director Kim Han-min’s upcoming historical action film. The teaser places Park at the center of a story set after the fall of Goguryeo, with the film currently being produced for a targeted 2027 theatrical release. 1
The image release has been presented as a global teaser rather than a standard domestic promotional still, signaling the production’s early effort to introduce the title beyond Korea. Reports identified Redice Entertainment and Solaire Partners as distributors connected to the teaser rollout, while Big Stone Pictures was named in coverage of the production-side announcement. 2 3
Red Wolf Teaser Shows Park Bo-gum as Chilsung

The newly released teaser image focuses on Chilsung, the character played by Park Bo-gum. Source summaries describe him as a Goguryeo warrior who has lost the memory of his past and entered a gladiatorial contest. The visual foregrounds a rougher appearance for the actor, including long hair, a beard, and an intense gaze, aligning with the character’s status after losing both memory and freedom. 4
Chilsung is described across reports as a man who becomes enslaved after losing his memories and is drawn into a fight over a legendary sword. In the premise reported by multiple outlets, the story follows him as he enters a gladiatorial arena where the legendary blade is at stake. 1 5
The Red Wolf label attached to the teaser has been used in Korean coverage to frame Park’s transformation for the role. The emphasis is not on a completed plot reveal but on a first character impression: a warrior marked by hardship, stripped of his past, and placed in a violent contest tied to the central sword. No confirmed full trailer, detailed release date, or additional official plot breakdown was included in the supplied reports.
Historical Action Film Set After Goguryeo’s Fall
Kal: Godumakhanui Geom is set in 668, immediately after the collapse of Goguryeo, with Liaodong Fortress identified as a key setting. The film is described as a historical action blockbuster built around a man who has become a slave after losing his memory and who joins a gladiatorial contest involving a legendary sword. 1
The setting places the story in the aftermath of a major historical rupture, but the available source material focuses on the fictional action premise rather than a detailed historical account. Reports consistently identify the film as a period action work, with the gladiatorial contest and the legendary sword serving as the central narrative elements available so far. 6
Kim Han-min directs the film. The director’s name is one of the confirmed production facts repeated in coverage of the teaser release, along with Park Bo-gum’s lead role. The currently reported cast also includes Joo Won, Jung Jae-young, Lee Sun-bin, and Tran Thanh. 2
Coverage of the teaser also notes that the film is being positioned for overseas audiences as well as Korean viewers. Dispatch reported that the project is targeting viewers in Japan and Vietnam in addition to the domestic market, while iMBC Entertainment described the teaser as aimed at the global market. 5 4
Filming Status and 2027 Target Release
Production on Kal: Godumakhanui Geom began in March 2026, and the film is being made with a target release in 2027. That schedule was reported in connection with the May 7 teaser reveal, but the supplied source material does not include a confirmed release month, exact opening date, rating, runtime, or final distribution schedule. 1
The May 7 teaser release therefore functions as an early production milestone rather than a full launch of theatrical information. The confirmed details available at this stage are the title, director, main cast, central premise, historical setting, Park Bo-gum’s role as Chilsung, the March 2026 filming start, and the 2027 release target.
Because the available reports center on one teaser image, the current public-facing information remains limited. There are no source-backed details in the provided material about additional character posters, soundtrack plans, official still galleries, or a trailer schedule. The reports also do not provide confirmed international release dates, even though the film is being introduced with a global market angle.

The Red Wolf teaser establishes Park Bo-gum’s Chilsung as the first major promotional image for Kal: Godumakhanui Geom, while the film continues production toward a planned 2027 release. With its post-Goguryeo setting, gladiatorial premise, and global teaser rollout, the project is now publicly positioned as Kim Han-min’s next large-scale historical action film.
