Early life
He grew up in Andong, a city in North Gyeongsang Province famous for its traditional culture. He studied theatre and film at Chung-Ang University in Seoul. After graduating, he chose the hard road of stage and small screen roles, building real skill year after year. Directors knew his talent long before the public learned his name.

He debuted on stage in Three Sisters in 2001 and on film in Once Upon a Time in a Battlefield (2003). For years he played minor characters. His turning point came with Descendants of the Sun (2016) and Guardian: The Lonely and Great God (2016), where Park Joong-heon, a wicked eunuch whose ghost returns for revenge, scared and thrilled viewers.

Doctor Prisoner (2019) confirmed his power. In All of Us Are Dead (2022), Lee Byeong-chan, a desperate teacher whose experiment starts a zombie outbreak, gave the horror story its human pain.
Recent work
