Mousetrap: Netflix Sets New Thriller Series Starring Ryu Jun-yeol and Sul Kyung-gu
Netflix has set a high-stakes Korean thriller series featuring actors Ryu Jun-yeol and Sul Kyung-gu in lead roles. Directed by Kim Hong-seon, the project is currently in post-production and is expected to premiere on the global streaming platform in 2026. The series explores themes of identity theft and psychological tension, adapted from the original Kakao Webtoon Field Mouse by Ludvico.
Production and Creative Direction
The series is helmed by director Kim Hong-seon, a filmmaker recognized for his work in the thriller and action genres, including titles such as Project Wolf Hunting and Metamorphosis. According to production announcements, the screenplay is written by Lee Jae-gon, with the musical score composed by Kim Tae-seong. The production involves a collaboration between H House, C-JeS Studios, and Kakao Entertainment. Filming for the project began in April 2025 and concluded in November 2025, moving the series into its current post-production phase.
Plot and Narrative Premise
Mousetrap centers on Je Mun-jae, a reclusive novelist whose life unravels when he discovers that his identity, fortune, and digital access have been stolen by a mysterious figure known as “Rat.” The narrative follows Mun-jae as he attempts to reclaim his life, eventually forming an uneasy alliance with a ruthless loan shark and a private investigator. The story is based on the webtoon Field Mouse, which ran from 2017 to 2020 and examined the vulnerability of personal security in an increasingly digital society.
