10 Choi Min-sik As Kyung-chul

I Saw the Devil (2010)

The role of Kyung-chul, played by Choi Min-sik in the film I Saw the Devil, was a performance that would make one's hair stand on end. A psychological serial killer, Choi brings alive something akin to pure evil with a phenomenal degree of precision.

His acting brings finesse to the sadistic nature of the character, which makes Kyung-chul one of the most memorable villains in Korean cinema.

Hauntingly present, even after the movie's over, Kyung-chul is menacing, which proves no other actor is quite like Choi Min-sik.

9 Kwak Do-won As Jong-goo

The Wailing (2016)

In The Wailing, Kwak Do-won turns in an unforgettable performance as Jong-goo, a bumbling police officer turned desperate father.

He has grasped the character's fear, confusion, and determination so sincerely that one cannot help feeling his angst.

Kwak Do-won's portrayal of Jong-goo serves as a master class in acting out a myriad of emotions. His character portrays desperation, and finally, his decision to fight the threat of the supernatural gives this film its emotional core and the twists The Wailing is known for. The range of Kwak to move from comic relief to a figure of tragic heroism is one of the greatest strengths of the movie, which makes Jong-goo's journey compelling and poignant.

8 Gong Yoo As Seok-woo

Train to Busan (2016)

In the film Train to Busan, Gong Yoo as Seok-woo offers an exciting and touching performance: a workaholic dad attempting to make amends with his daughter on a train when a zombie outbreak occurs. He gave character depth to this workaholic father, from selfish to unselfish, in this work. His performance anchored the film, thus making the journey of Seok-woo, one of redemption and sacrifice, incredibly moving.

​​​​​​

From being an aloof, distracted father to a hero who will go all out for his daughter, the character arc of Seok-woo himself has changed -- a metamorphosis. This subtlety act by Gong Yoo added more depth to a horror movie about fatherhood. He proves his worth as an actor in this role, bringing humanness and intensity into the performance.

She captures the bravery of Seo-hee in the face of unimaginable danger. This sheds a compelling light on the storyline of the film.

Seo-hee's character shows not only physical but also mental strength. It is the way Bae Doona conveys these two facets credibly that makes her performance outstanding. The determination with which she wants to save her family at all costs forms a strand in the plot of the film, and Bae does this in a manner where it would strike the right chords in an audience member's heart.

6 Ha Jung-woo As Hyun-soo

The Terror Live (2013)

Ha Jung-woo's performance in The Terror Live is a tight-wire tension act. As Hyun-soo, a disgraced news anchor who is allowed to redeem himself when he receives a live call from a terrorist, Ha infuses the role with intensity and urgency. His portrayal of his inner mental and emotional turmoil keeps audiences at the edge of their seats throughout the live transmission.

Almost the entire movie was shot in real time. Ha Jung-woo thus had to sustain his intensity for a very long period while filming.

The real-time format of the film put a lot of pressure on the lead actor, but Ha Jung-woo was up for it. It is amazing how he maintains this intensity right until the movie's end, making the plight of Hyun-soo riveting and credible. Indeed, Ha's performance was the real key to making this film work, having turned what might seem at first glance like a restricted setting into an absorbing thriller.

5 Kim Yoon-seok As Jung-ho

The Chaser (2008)

Kim Yoon-seok's performance as Jung-ho in The Chaser is powerful. He plays a former, disgraced detective turned pimp who becomes quite the man on a mission when he learns that one of his girls has gone missing. His portrayal brought out a sense of grit and intensity in the relentless pursuit of finding the killer by Jung-ho.

Jung-ho is morally ambiguous, and Kim Yoon-seok, playing the role of the investigator, navigates subtle lines between his quest for justice and his inner persona. He evoked raw and trenchant realism that found the audience in his corner despite his flaws. Added to all this, the high octane levels in chase scenes and moments of vulnerability show Kim's great range as an actor.

4 Park Hae-il As Nam-il

Memories of Murder (2003)

In the film Memories of Murder, Park Hae-il makes a strong impression as Nam-il. The actor brings into the film a young detective who is to be faced with his very first serious case: a serial killer. It captures the development of his character from inexperienced and frustrated to determined and resilient. His performance adds depth to the film's exploration of human fallibility and justice.

​​​​​

In such a scenario, Nam-il's character arc becomes pivotal for the story. Subtle shades in the performance by Park Hae-il ensure that all aspects of his journey are brought credibly to the forefront. Frustration, determination, and eventually, the disillusionment of Nam-il is done so subtly that it makes the story of this character relatable and impactful. He stands out in a film full of memorable roles.

3 Kim Ok-bin As Tae-ju

Thirst (2009)

Kim Ok-bin is astonishing as Tae-ju in Thirst. As the wife of a sickly man who has become a vampire, Kim explores a woman deeply torn between her newfound power and moral conflict. That performance was sensual and haunting, securing Tae-ju's place as one of the most unforgettable creations in Korean horror movies.

Kim Ok-bin trained her body rigorously for the role, even learning martial arts to do stuntperson work herself.

The main merit of the film belongs to Kim Ok-bin, who shapes Tae-ju's evolution from a meek homemaker into a formidable, morally ambiguous character in a deep way. She can express the interior struggle of the character and finally give in to her dark side, which makes the movie interesting. Provocative and thought-provoking, Kim's performance makes Thirst one of the most remarkable representatives of the vampire genre.

2 Lee Byung-hun As Sun-woo

A Bittersweet Life (2005)

The performance that Lee Byung-hun gave as Sun-woo in A Bittersweet Life is a real tour de force. As an enforcer who has been appointed to display "tough love" but does so with a questioning attitude toward life choices, Lee Sunderbac infuses his character with a nuanced portrait of a man in search of merit, which stands as redemption. The ability to express both the physical strength and the emotional fragility of Sun-woo makes his journey both riveting and tragic.

​​​​​​

Thus, in the film, we have a narrative focused on the inner turmoil of Sun-woo and the subsequent quest for redemption. Lee Byung-hun makes sure we feel each moment of that journey. He makes his performance intense yet subtle enough to balance it out, so he assumes the character very powerfully yet so relatable. The role of Lee in A Bittersweet Life proved to be a guarantee of his versatility in acting.

1 Kim Hye-soo As Hye-jung

The Thieves (2012)

The performance of Kim Hye-soo as Hye-jung was way out among the other prominent characters in The Thieves. For a talented, ruthless thief, Kim gave the much-needed charm and character depth. Her rendition of Hye-jung as intelligent and full of resources makes the heist movie thrilling; she becomes highly memorable and interactive.

Kim Hye-soo did most of the difficult stunts, which involved wire work, by herself so that her role as a master thief seemed more plausible.

Hye-jung's character is like the binding force of the group, and Kim Hye-soo makes that very believable and engaging. She maneuvers quite well as the character reveals the strategic thinking and emotional depths of her persona, adding depth to the film. Kim's characterization of Hye-jung in The Thieves is one of the standouts of the work, showing her talent and versatility.
