Son Suk-ku

Son Suk-ku, born on February 7, 1983, is a South Korean actor whose rise from supporting parts to leading roles has been marked by sharply contrasting characters. He studied film at the School of the Art Institute of Chicago and made his screen debut in the 2014 film Scarlet Innocence. International viewers first encountered him in Netflix’s Sense8, where he played Detective Mun, a Seoul police officer who becomes involved with Sun Bak’s storyline. He later appeared in the 2017 Netflix series Black as a detective.

His Korean television profile expanded through roles in the political thriller Designated Survivor: 60 Days and the 2019 drama Be Melodramatic, where he played director Sang-su. In D.P., adapted from Kim Bo-tong’s webtoon, he portrayed Captain Im Ji-sup, an officer attached to the military police unit that pursues deserters. The series places its characters amid hazing, violence, and institutional failures within South Korea’s compulsory military service.

A major breakthrough came with JTBC’s 2022 drama My Liberation Notes. Son played Mr. Gu, a taciturn outsider living in Sanpo Village who forms an unusual bond with Yeom Mi-jeong, played by Kim Ji-won. The drama, written by Park Hae-young, follows three siblings commuting from the fictional village to Seoul while seeking a more fulfilling life. Mr. Gu’s request that Mi-jeong “worship” him became one of the show’s most discussed lines.

In 2022, he reached a far wider domestic audience in The Roundup, the sequel to The Outlaws. He played Kang Hae-sang, a Vietnamese-Korean kidnapper and murderer pursued by detective Ma Seok-do, played by Ma Dong-seok. The film became a major box-office success in South Korea, and Son’s villain was central to its impact. He returned to crime storytelling in Disney+’s Casino, also known as Big Bet, portraying Jang Jun, a prosecutor investigating casino operator Cha Mu-sik.

In 2024, Son starred as Detective Jang Nan-gam in Netflix’s A Killer Paradox. The adaptation of Kkomabi’s webtoon pairs him with Choi Woo-shik, who plays Lee Tang, an ordinary young man drawn into serial killing after a fatal confrontation. Jang pursues Lee while suspecting that his crimes may be linked by the victims’ hidden wrongdoing. That same year, Son led the film Troll Factory as Im Sang-jin, a journalist investigating an online opinion-manipulation operation. Across these projects, he has moved between introspective television, franchise-scale action, and crime narratives, while repeatedly playing figures whose motives remain difficult to read on screen.
