Kim Ji Woong and Kang Ki Young Star in Police Buddy Film ‘Siren’, Set for 2027
Kim Ji Woong will make his feature-film debut opposite Kang Ki Young in the buddy-investigation comedy ‘Siren’. Production has already completed filming and is targeting a 2027 release.
Kim Ji Woong, known to music fans through ZEROBASEONE, is taking a major step into film. Production company Take One confirmed on October 19, 2026 that he stars opposite actor Kang Ki Young in Siren, a new detective comedy directed by Oh Ki Hwan.
The production update says principal filming is already complete and post-production is under way, with a 2027 theatrical release targeted. No fixed cinema release date has been announced, so the year should be understood as a goal rather than a guaranteed opening day.
Two police officers from different worlds
The premise turns on a sharp mismatch between two characters. Kim Ji Woong plays Do Yoon, the youngest son of the wealthy Kangsung Group and a police academy trainee. Although he has enjoyed material privilege, an event in his past led him to pursue police work seriously.
Kang Ki Young plays Si Woo, an experienced detective working at Gangnam Police Station who faces financial and professional pressure. The two characters first collide during an investigation and then find themselves assigned to a senior-and-trainee relationship.
The comedy emerges from their competing approaches to the job. Si Woo tries to persuade Do Yoon to give up, while Do Yoon refuses to leave and uses his resources in unexpected ways. Their disagreements gradually push them toward cooperation on a case. The story has been described as a buddy investigation comedy, not a music-industry documentary or a film about Kim’s idol career.
Kim Ji Woong’s character and the move to the big screen
Do Yoon is not presented as a bored heir experimenting with a hobby. The announced character description gives him a personal reason to become a police officer and a serious determination to succeed. That creates opportunities for performance opposite a veteran comic actor whose character would rather work alone.
For Kim Ji Woong, the project marks his first feature-film role, according to production coverage. He has previously appeared in screen productions, so “film debut” should not be mistaken for “first acting role.” The news introduces a new format and a prominent co-star while remaining separate from the music activities associated with ZEROBASEONE.
The project is already in post-production
An important detail in the October 19 update is timing. Rather than announcing that cameras will start rolling soon, the production team reports that Siren has completed filming. The next stages will include editing, sound and marketing before a cinema release can be finalised.
Because a film can still change in post-production, there are no grounds yet to claim a precise running time, final trailer schedule, premiere city or box-office outlook. Those facts should come from Take One’s later official announcements or distribution details.
What fans should watch next
The headline pairing of Kim Ji Woong and Kang Ki Young offers a clear premise and two distinct character roles. The next reliable milestones will be the distributor’s confirmed release date, promotional artwork, a trailer and any film-festival plans. Until those arrive, the verified news is the casting, the completed shoot and the targeted 2027 release.
