Kim Ju-hun
BIOGRAPHY
Kim Ju-hun (Korean: 김주헌; born 1 March 1980 in Pohang, North Gyeongsang) is a South Korean actor with thirty-eight productions on record. He is one of the most widely seen supporting actors in Korean television and film of the past decade.
His earliest credit is the KBS Drama Special anthology in 2010. Film work followed through the mid 2010s, including the baseball team manager in Train to Busan (2016), and he has appeared in Tazza: The Hidden Card (2014), The Accidental Detective (2015), The Princess and the Matchmaker (2018), A Man of Reason (2023) and Mission: Cross (2024).
On television he has played Park Min-guk across thirty-two episodes of Dr. Romantic (2016), Lee Dae-chan in Encounter (2018), Lee Sang-in in It’s Okay to Not Be Okay (2020), Cha Eun-seok in Do Do Sol Sol La La Sol (2020), Seok Do-hoon in Now, We Are Breaking Up (2021), Bae In-cheol in Extraordinary Attorney Woo (2022), Choi Doha across sixteen episodes of Big Mouth (2022), Lee Seo-joon in Castaway Diva (2023), Choi Sang-rok across twenty episodes of Missing Crown Prince (2024) and Park Dong-ah in When the Stars Gossip (2025).
His work inside this site’s remit is Do Hyeon-su across twelve episodes of Four Hands, Two Sonatas, which began on 29 August 2026.
BLGLFlix editorial view
The years active field said “2000s-present”. His first credit is May 2010, and the field now says that instead.
He is the strongest single piece of evidence we have for something this site keeps circling. When a Korean queer drama casts him, it is not casting an unknown or a genre specialist. It is casting the antagonist from Big Mouth, a man who has been on screen in Train to Busan, Extraordinary Attorney Woo and It’s Okay to Not Be Okay, which is to say most of what a Korean television audience watched between 2016 and 2024.
There is a smaller find in the overlap. He and Lee Ji-hae, whose page we rewrote in the same session, both appear in Dr. Romantic, It’s Okay to Not Be Okay, Now, We Are Breaking Up and Extraordinary Attorney Woo. Four shared productions between two supporting actors who have never been billed together is a fair measure of how small the working pool actually is.
