Honestly, it’s been about a decade since W: Two Worlds first messed with our heads, and people are still obsessed. I get it. The show basically took the "isekai" trope, dunked it in a vat of K-drama angst, and gave us a lead actor who looked like he actually stepped out of a drawing.
When you look back at the w cast korean drama lineup, it's wild to see where they started and where they've landed by 2026. Most fans remember the chemistry between Lee Jong-suk and Han Hyo-joo—which, let’s be real, was electric—but the supporting cast is where the real "wait, they were in that?" moments happen.
The Power Duo: Lee Jong-suk and Han Hyo-joo
Lee Jong-suk didn't just play a webtoon character; he was Kang Chul. Before this, he was already huge, but W turned him into a literal blueprint for the "perfect man" archetype. Fast forward to today, and he's still a titan. He’s currently making waves in the 2026 Disney+ epic The Remarried Empress, playing Prince Heinrich. It’s a total 180 from the modern, tech-savvy chaebol of W, showing he’s still got that "I can pull off anything" energy.
Then there’s Han Hyo-joo. Her portrayal of Oh Yeon-joo was kinda polarizing back in 2016. Some people loved her relatable, slightly chaotic doctor vibes; others thought the writing turned her into a damsel toward the end. But Han Hyo-joo proved everyone wrong by becoming one of Korea’s most versatile action stars. If you haven’t seen her in Moving or Happiness, you’re missing out. She’s currently filming a Japanese production called Romantics Anonymous, proving her reach is way beyond just Seoul.

The Supporting Players Who Stole the Show
You can't talk about the W cast without mentioning Kim Eui-sung. He played the double role of Oh Seong-moo (the creator) and the Faceless Killer. That man’s range is terrifying. One minute he’s a grieving, alcoholic father, and the next, he’s a literal nightmare without a nose.
He’s basically the go-to villain in Korean cinema now.
What about the rest of the crew?
- Lee Tae-hwan (Seo Do-yoon): He played Kang Chul’s loyal bodyguard. He’s been consistently working in rom-coms and recently finished his military service, returning to the screen with a more mature vibe.
- Jung Yoo-jin (Yoon So-hee): The "rejected" second lead. She’s since become a staple in "career woman" roles, often playing sophisticated characters in dramas like Remarriage & Desires.
- Lee Si-eon (Park Soo-bong): The real MVP. His reactions to the supernatural craziness were basically the audience's inner monologue. He’s still one of the most beloved character actors in the industry.
Why the W Cast Korean Drama Still Hits Different
There’s a reason we aren't talking about other 2016 dramas with this much intensity. The casting wasn't just about big names; it was about finding people who could sell the absurdity of jumping into a tablet.

Think about the scene where Kang Chul realizes his life is just a series of ink strokes. Lee Jong-suk’s face in that moment? Pure existential dread.
The drama also touched on something meta that we see a lot of now—the idea of "NPCs" or side characters gaining consciousness. Watching the supporting cast "fade away" when they weren't needed for the plot was genuinely haunting. It gave the actors a chance to play with some really dark, psychological themes that weren't common in romance dramas at the time.
Recent Updates and 2026 Projects
If you're looking to catch the cast in something new, 2026 is actually a massive year for them.

Lee Jong-suk’s The Remarried Empress is arguably the most anticipated project on Disney+ right now. It’s a medieval fantasy, which is a bit of a departure for him, but the hype is real. Han Hyo-joo is sticking to her "global star" path, balancing Korean projects with high-budget Japanese dramas.
Interestingly, there’s always talk of a remake or a "Season 2," but honestly? The original cast is so synonymous with these roles that it would be hard to buy anyone else in them. There was a Malaysian remake recently, and while it was decent, it just didn't have that specific Jong-suk/Hyo-joo spark.
Actionable Insights for Fans
If you're planning a rewatch or trying to follow the cast's current careers, here’s how to do it right:
- Watch the "Special Episodes": Most streaming platforms skip the "W-Special" episodes that aired during the original run. They have some of the best behind-the-scenes chemistry footage that explains why those kiss scenes felt so real.
- Follow the "Moving" Connection: If you loved Han Hyo-joo in W, watch her in Moving (2023). It’s the closest thing to the "supernatural thriller" vibe of W but with 2020s production values.
- Check 2026 Release Calendars: Keep an eye on Disney+ for Lee Jong-suk's new series. It’s expected to drop in the second half of the year.
- Explore the Webtoon: If the drama left you confused, the actual webtoon art created for the show is often available in fan archives. It adds a whole new layer to the "Two Worlds" experience.
The legacy of the W cast isn't just that they made a hit show. It's that they used that momentum to become some of the most influential actors in the Hallyu wave today. Whether they're playing comic book heroes or empresses, they’ve still got that "it" factor.
