You’ve seen him. Maybe you didn't know his name at first, but you definitely knew the face. Choi Won-young is basically the glue holding the South Korean television industry together. He’s that actor who can play a doting, idealistic father in one series and a chillingly calculated corporate psychopath in the next. Honestly, it’s a bit jarring.
Most actors find a lane and stay in it. Not him. If you look at the catalog of Choi Won-young TV shows, you'll see a career built on being unpredictable. He doesn't just "show up"; he transforms.
The Roles That Changed Everything
People often point to Sky Castle as the moment he truly became a household name. In a show filled with high-octane drama and toxic parenting, his character, Hwang Chi-young, was a breath of fresh air. He was the moral compass. He played a neurosurgeon who actually cared about ethics—a concept that felt like a foreign language to the other characters in that wealthy neighborhood.
But then, he flipped the script.
Shortly after being the "good guy" in Sky Castle, he jumped into Doctor Prisoner. If you haven't seen it, go watch it. He plays Lee Jae-joon, a chaebol heir with a darkness that makes your skin crawl. He’s refined, he’s rich, and he’s absolutely terrifying. This specific pivot is why casting directors love him. He can move from the hero to the villain without breaking a sweat, and the audience buys it every single time.

Recent Hits and 2026 Appearances
Fast forward to more recent years, and he’s still everywhere. He was the King in Under the Queen's Umbrella, balancing the weight of a crown with the complexities of being a father to many princes. It wasn't just a "king" role; it was a nuanced look at a man caught between his mother's ambitions and his own sense of justice.
As of early 2026, he’s still keeping us on our toes. He recently made a special appearance in the tvN drama Undercover Miss Hong, playing Kang Myung-hwi, the CEO of Hanmin Securities. Even in a guest role, he managed to trigger a massive plot shift through a sudden, mysterious death. That’s the Choi Won-young effect: he leaves a mark even if he’s only on screen for a few episodes.
A Career Built on Range
He didn't start at the top. Choi debuted way back in 2002 in the film Sex Is Zero. Since then, his TV journey has been a masterclass in longevity.
- The Heirs (2013): He played Yoon Jae-ho, showing us that "cool, capable secretary" energy.
- Kill Me, Heal Me (2015): He was the loyal assistant Ahn Gook. Honestly, everyone needs an Ahn Gook in their life.
- Mystic Pop-up Bar (2020): He moved into the supernatural as Chief Gwi. It was funny, it was heartfelt, and it proved he has great comedic timing.
- The Golden Spoon (2022): Back to the "villainous dad" vibes as Hwang Hyeon-do. He won the Best Character Award at the MBC Drama Awards for this one, and it was well-deserved.
What's wild is his background. He actually studied Stage Design at Sangmyung University and has a Master’s in Advertising and Public Relations from Hongik University. Maybe that's why he understands the "look" and "branding" of his characters so well. He isn't just reciting lines; he's designing a persona.

What to Watch Next
If you are looking to dive into his filmography, don't just stick to the hits.
Check out Twinkling Watermelon (2023). He plays the adult version of Ha Yi-chan, and the emotional payoff is huge. It’s a series about music, family, and the things we leave unsaid. It’s a softer side of him that people often forget exists because he's so good at playing the "bad guy."
Also, keep an eye out for his upcoming role in the Disney+ historical drama The Murky Stream. He's set to play Prince Dae Ho. It’s his first major return to the sageuk (historical) genre since Under the Queen's Umbrella, and word is his character has some pretty massive ambitions for Joseon.
The Realistic Side of Acting
Acting isn't all glitz for him. He’s spoken in interviews before about the pressure of being a "character actor." You aren't always the lead, but you're often the reason the lead looks good. He’s married to actress Shim Yi-young—they actually met while playing a married couple in A Hundred Year Legacy back in 2013. Talk about life imitating art. They have two daughters now, and he’s often praised for being a "reliable" actor who manages to balance a busy filming schedule with a stable personal life.

How to Navigate His Filmography
To truly appreciate Choi Won-young, you have to watch his shows in "tonal pairs."
Try watching an episode of Sky Castle followed by an episode of Doctor Prisoner. The contrast is insane. It’s like watching two different people. Most viewers struggle with this because they want to put actors in a box. We want the "dad" actor to always be the dad. Choi refuses that box.
- For Thrills: Doctor Prisoner, Reflection of You, Mad Dog.
- For Comfort: Twinkling Watermelon, Mystic Pop-up Bar, Family by Choice.
- For Drama: Sky Castle, The Golden Spoon, Under the Queen's Umbrella.
The Verdict for 2026
Choi Won-young remains one of the few actors who can guarantee a certain level of quality. If he’s in the cast list, the show has weight. Whether he's a cameo in Undercover Miss Hong or a lead in a historical epic, his presence is a signal to the audience that the story matters.
If you’re building a K-drama watchlist, skip the idol-heavy fluff for a second and look for the name Choi Won-young. You won't be disappointed.
To get started with his most versatile work, begin with Doctor Prisoner for his dark side and Twinkling Watermelon for his heart. These two performances provide the full spectrum of his capability. Once you’ve seen those, track his 2026 projects like Undercover Miss Hong and the upcoming The Murky Stream to see how he continues to evolve in the current landscape of Korean television.
