The Netflix streaming platform with its global accessibility and over 300 million subscribers can turn established Korean actors into global superstars almost overnight. This was the case with Lee Jung-jae following the unprecedented success of Squid Game (2021-2025). Less well-known talent can also see their followings on social media explode as seen with the young cast of All of Us are Dead (2022). The star system has changed.

Kim Moo-yeol has similarly benefited from the wide reach of Netflix having been the lead in the series Teach You a Lesson (2026) that is now on the streamer’s top ten most-viewed Non-English language shows with more than 63 million views to date after dropping on the platform in June of this year. While he is a seasoned actor with two decades of experience the popularity of the series has taken his career to new heights.

Kim Moo-yeol’s First Hit: War of the Arrows

War of the Arrows (2011)

After performing in musicals in Seoul and making appearances in television series on Korea’s terrestrial broadcasting stations he made his debut in film in 2009 with Lee Ho-jae’s The Scam (2009) that centers on Korea’s stock market in which he played a bond broker. His first hit came two years later with Kim Han-min’s War of the Arrows (2011) that became the most-viewed Korean film of 2011 accruing more than 7.4 million admissions. Like his early roles Kim plays a significant part, but he has often been overshadowed by the main leads. Starring Park Hae-il as a skilled archer who searches for his sister when she is kidnapped, Kim acted as one of the protagonist’s companions and the man who is to marry the archer’s sister. The success of the film gave him the platform from which he could build on for his subsequent roles.

 Making his mark in Eungyo (aka The Muse)

 
Eungyo (2012)

His next notable performance was in Jung Ji-woo’s Eungyo (2012) reuniting with Park Hae-il that was an adaptation of Park Bum-shin’s novel. The film follows a 70-year-old poet who falls in love with a high school student (Kim Go-eun) and writes a book about it. As the two get closer, the poet’s protégé acted by Kim Moo-yeol becomes jealous and angry towards his mentor and publishes the book under his own name.

Ultimately it was Kim Go-eun who would win multiple awards for her role in the film launching her very successful career, but it also showcased Kim’s talent as a promising actor with much range that would be evident in later performances. The films he appears in simply don’t work as well without him there.

Top Billing in Northern Limit Line

 Northern Limit Line (2015) 

His first top billing in a commercial studio film was in Kim Hak-soon’s naval thriller Northern Limit Line (2015) that is based on the Second Battle of Yeonpyeong where North and South Korean patrol boats were engaged in combat when North Korean ships crossed the maritime border in 2002, the year when South Korea co-hosted the world cup. Kim takes on the role as the ship’s captain, while Lee Hyun-woo and Jin Goo are also on board as sailors as they come up against North Korea’s navy. The film performed robustly at the box office accruing 6 million admissions further raising Kim’s profile.

Starring in one of Netflix Korea’s Early Acquisitions Forgotten

 The Gangster, The Cop, The Devil (2019) 

After Kim starred in Jeong Yoon-cheol’s historical drama Warriors of the Dawn (2017) that was financed by 20th Century Fox (before the studio was acquired by Disney), Kim appeared as the lead opposite Kang Ha-neul in the mystery thriller Forgotten (2017). Directed by Jang Hang-jun whose career was under the spotlight following the smash hit The King’s Warden (2026), it’s a film that gave Kim some international exposure. The inventive film, which centers around the disappearance of a man played by Kim was one of the first Korean films to be acquired by Netflix as an original in 2017. It was picked up by the streamer in its scriptwriting stage.

In 2018 Kim played leading roles in Snatch Up (2018) and Kim Jee-woon’s eagerly awaited dystopian film Illang, The Wolf Brigade (2018) starring opposite Kang Dong-won. Although the film failed to live up to expectations Kim demonstrates his agility as an actor playing the central villain as a high-ranking corrupted official when different government organizations come into conflict with each other as North and South Korea agree to reunify.

A year later, Kim took on the role of a cop in Lee Won-tae’s thriller The Gangster, The Cop, The Devil (2019) starring alongside Don Lee (aka Ma Dong-seok) that was invited to the Midnight Section of the Cannes Film Festival.

A New Chapter in the 2020s

 The Roundup: Punishment (2024)

In the 2020s despite an industry slowdown Kim remained busy and evidently in demand featuring in Honest Candidate (2020), Intruder (2020), On the Line (2021), Honest Candidate 2 (2022) and The Devil’s Deal (2023). Perhaps his most significant role was as the antagonist The Roundup: Punishment (2024) working again with Don Lee that amassed over 11 million admissions. It is indeed true that the driving force behind the most successful franchise in Korean box office history (they have collectively accumulated more than 40 million admissions) is its action hero (Don Lee) but it’s also his foes that turn the films into hits. Kim joins Yoon Kye-sang and Son Suk-ku as memorable and highly effective villains of the series.

Kim’s most recent film credit is in Min Kyu-dong’s action thriller The Old Woman with the Knife (2025) that like The Roundup: Punishment was invited to the Berlin International Film Festival. It’s a smaller role but reflects his appetite to take on an array of different characters as seen with his casting in Teach You a Lesson that generated much discussion in Korea surrounding its themes of discipline in and out of the classroom.

Looking ahead, Kim Moo-yeol now enters a new exciting chapter in his career as he can potentially take advantage of that international exposure that some of his peers are experiencing with Korea’s content industry turning increasingly global. It also reflects how talent from Korea’s film industry has migrated over to streaming that continues to bring about challenges for Korean cinema.
