Kim Do-yoon

Kim Do-yoon is a South Korean character actor whose face viewers trust, even when his characters cannot be trusted at all. Born on 7 August 1981 in Seoul, he built his skills on the theatre stage before films and dramas found him. Oxfea fans know him as Lee Dong-wook, the loud Arrowhead streamer in Hellbound (2021), and as Park Min-hwan in Love in Disguise (2026).

He stands about 5 feet 11 inches (181 cm) tall and weighs about 67 kg.

Early life

He studied theatre and film at Chung-Ang University and spent years acting in plays, learning how to change his voice, body and energy for every new role. That stage training is still clear in his screen work today: he never plays two men in quite the same way, and even his smallest parts feel fully lived in and real.

Career and breakthrough

He began in films in 2012 with small roles, including a police officer in 26 Years (2012). His breakthrough came in the horror hit The Wailing (2016), where he played Yang I-sam, the young deacon who speaks Japanese and helps in the fight against a strange and terrible evil. The film was a huge success, and directors now had a new and flexible actor to call.

Popular roles

In Peninsula (2020), the follow-up to Train to Busan, he played Sergeant Kim, fighting to survive in a ruined Korea. He also appeared in the comedy hit Luck-Key (2016). In Hellbound (2021), he was unforgettable as Lee Dong-wook, the masked online streamer who leads the violent Arrowhead group and shouts the cult's message out to the world.

Recent work

He stayed in demand with Concrete Utopia (2023), Song of the Bandits (2023) and Queen Woo (2024). In Love in Disguise (2026), he plays Park Min-hwan, adding one more colour to a career full of soldiers, detectives, villains and ordinary men. He is exactly the kind of actor who makes every story around him feel stronger.
