Kim Sung-cheol

Kim Sung-cheol (김성철, born December 31, 1991, Seoul) trained as a musical actor before television discovered him. He debuted on stage with the musical Puberty in 2014 and won Best Rookie Actor at the Korea Musical Awards in 2017 for his role as Tobias Ragg in Sweeney Todd. The stage background gives him something rare in Korean television: a technical precision that makes even supporting roles land harder than they should.

His TV breakthrough came that same year in Prison Playbook (2017), playing Kim Young-cheol, a.k.a. Jailbird -- a comic-dramatic role that turned him into a face Korean audiences immediately trusted. From there, the credits compounded: the apocalyptic Netflix series Sweet Home (2020), the SBS romantic drama Our Beloved Summer (2021), the Vincenzo cast, Hellbound 2 (2024), and the thriller No Way Out: The Roulette (2024). In 2025, he starred in the Netflix action film The Old Woman with the Knife alongside Kim Hye-soo -- his highest-profile film role to date. For 2026, he joins the Disney+ crime-thriller Gold Land as Jang Wook, a debt collector caught in a gold smuggling conspiracy alongside Park Bo-young, Lee Hyun-wook, and Lee Kwang-soo.

Kim Sung-cheol is represented by Story J Company and brings a rare musical theater foundation to a screen career built on genre versatility.
