Yoo Seung-mok, ‘Good Man’ → ‘I Kill You’ Active Career

Actor Yoo Seung-mok is delivering a realistic performance.

Yoo Seung-mok, who expresses characters in his own unique color in every work regardless of genre, is undeniably showcasing his presence as a ‘prolific actor’. Through tvN’s ‘Potato Research Institute’, Disney+’s ‘Hyper Knife’, the independent film ‘Moonwalk’, and the movies ‘Lobby’ and ‘High Five’, Yoo Seung-mok has been actively working in the first half of 2025, and in the second half, he continues to demonstrate solid acting skills that change the flow of the drama while filling his diverse filmography.

In JTBC’s Friday series ‘Good Man’, Yoo Seung-mok plays the role of ‘Jakdaegi’, the right-hand man of the notorious thug Park Sil-gon (played by Cheon Ho-jin), who saved his life, expressing what unconditional pure friendship truly means. The unique character of Jakdaegi, felt through his rough dialect and the intense and varied colors of his costumes, adds interest to the plot, and Yoo Seung-mok’s portrayal of Jakdaegi’s warm side completes a three-dimensional character.

Yoo Seung-mok surprises viewers by perfectly transforming into different characters in each work. While he was a warm neighborhood uncle in ‘Good Man’, he transformed into a charismatic politician in the suspense genre MBC’s Friday-Saturday drama ‘Mary Kills People’. Yoo Seung-mok, playing the multi-term congressman ‘Baek Ui-won’, delicately captures the complex psychology of parents who have lost their terminally ill son. His crazed gaze and unique sharp atmosphere heighten the tension in the drama as he pressures Police Chief Ahn Tae-seong (played by Kim Tae-woo) by any means necessary to arrest the murderer who caused his son’s death.

Moreover, Yoo Seung-mok has once again teamed up with director Yoo Ha, with whom he worked on the films ‘Gangnam 1970’ and ‘Pipeline’, for the new project ‘I Kill You’. After being screened at the 29th Bucheon International Fantastic Film Festival (BIFAN), the full version of the drama, which includes unreleased scenes, was released on the OTT platforms Wavve and Watcha on the 22nd (Friday). Yoo Seung-mok transforms into the chairman of a construction company, ‘Han Beom-soo’, delivering a powerful performance that crosses the boundaries of coldness and emotion, as he takes action without blood or tears to cover up incidents involving his only granddaughter.

In this way, Yoo Seung-mok’s diverse acting transformations have instantly captured the viewers’ attention. He can change the temperature of a situation just by appearing, balancing heavy narratives with humor that naturally brings laughter, solidly maintaining equilibrium in each work. With a wide acting spectrum, there is growing anticipation and interest in how Yoo Seung-mok will transform in the future.
