You’ve seen the clips. A massive man with arms the size of tree trunks walks into a crowded room, ignores a knife-wielding thug, and knocks him out with a single, casual slap. That’s Ma Dong-seok. Or Don Lee, if you’re following his Hollywood career. But before he was a Marvel Eternal, he was Ma Seok-do in the 2017 hit The Outlaws.
Honestly, the cast of the outlaws movie is the only reason the film works as well as it does. If you swap out the leads, you just have another generic cop thriller. Instead, we got a gritty, surprisingly funny, and ultra-violent masterpiece that launched a massive franchise. People keep searching for the "cast of the outlaws," but there's often a bit of confusion because of the BBC show and that Netflix comedy with Pierce Brosnan. We're talking about the South Korean powerhouse here. The 2004-set brawl in Garibong-dong.
Ma Dong-seok: The Man, The Myth, The Biceps
Let's be real. Ma Dong-seok is the sun that the rest of this cinematic solar system revolves around. He plays Detective Ma Seok-do. He isn't your typical "by the book" cop. He’s more of a "by the fist" kind of guy.
What’s crazy about his performance is the nuance. Yeah, he can punch through a wall, but he also has this weary, neighborhood-uncle energy. He’s trying to keep the peace between local gangs not just by arresting them, but by basically being the biggest shark in the tank. You’ve probably noticed his "truth room" technique—where he covers a suspect's head and "persuades" them to talk. It’s dark, sure, but Ma plays it with a wink that makes you root for him.
He actually helped develop the story based on real-life events from 2004 and 2007. It wasn't just a gig for him; it was a passion project. That shows in every frame.

Yoon Kye-sang as the Terrifying Jang Chen
If Ma Dong-seok is the unstoppable force, Yoon Kye-sang is the immovable (and incredibly scary) object. Before this, Yoon was mostly known as a K-pop idol from the group g.o.d. and for playing "nice guy" roles in romantic dramas.
Then he showed up as Jang Chen.
Long hair tied back, a cold stare, and an absolute obsession with hatchets. Jang Chen is a loan shark from Harbin, China, who moves into Seoul and decides he doesn't care about the existing gang hierarchy. He just wants money. Most villains in these movies have a big speech or a tragic backstory. Jang Chen just has a knife and zero remorse.
The contrast between him and the detective is what makes the movie electric. While Ma is trying to maintain a balance, Jang Chen is a chaotic fire burning everything down. You genuinely feel like Ma might actually lose for once because Jang Chen is just that ruthless.

The Supporting Players You Might Recognize
The cast of the outlaws movie isn't just a two-man show. The side characters are what give the Garibong district its flavor.
- Jin Seon-kyu (Wi Seong-rak): He plays Jang Chen’s right-hand man. He won a Blue Dragon Film Award for this role, and honestly, he deserved it. He’s unrecognizable. He shaved his head and adopted this twitchy, feral energy that makes him feel like a cornered animal.
- Jo Jae-yoon (Boss Hwang): He’s the local gang leader who finds himself caught between a rock (the cops) and a hard place (Jang Chen). He brings a bit of "business-man" sleaze to the role that balances the raw violence.
- Choi Gwi-hwa (Captain Jeon): He’s Ma’s boss. Their chemistry is hilarious. He’s constantly stressed out by Ma’s unorthodox methods but ultimately trusts his lead detective. Their bickering provides the much-needed levity in a movie where people are getting their hands chopped off.
- Kim Sung-kyu (Yang-tae): The youngest and perhaps most impulsive of Jang Chen's trio. He's the one who usually starts the trouble that the others have to finish.
Why the Casting Choice Changed Korean Cinema
Before 2017, Korean crime movies were getting a bit stagnant. They were either too "slick" and stylish or too depressing. The Outlaws found a middle ground. By casting a former idol as the lead villain and a guy who looks like a powerlifter as the hero, director Kang Yoon-sung broke the mold.
It’s about "physicality." In most movies, the fights are choreographed like dances. In this one, they feel like brawls. When someone gets hit, they stay down. The cast had to go through intense training to make the movements look unpolished and "real."
The success of this specific cast of the outlaws movie actually led to the "Roundup" sequels. The Roundup (2022), No Way Out (2023), and Punishment (2024) all feature Ma Dong-seok returning as the lead. It’s basically become South Korea’s version of Fast & Furious, but with more slapping and fewer cars jumping between skyscrapers.

Misconceptions About the Cast
People often mix this film up with the 2023 Netflix movie The Out-Laws. Total different vibe. That one is a comedy with Adam DeVine. If you're looking for the gritty detective work and the legendary airport bathroom fight, you want the 2017 Korean film.
Another common mistake? Thinking Ma Dong-seok is just an "action guy." If you watch his scenes with the neighborhood kids or his fellow officers, he’s a great comedic actor. His timing is impeccable. He knows exactly when to pause before delivering a line that defuses a tense situation.
How to Appreciate the Cast Even More
If you want to see how versatile these actors are, you've gotta check out their other stuff. It puts The Outlaws in a whole new perspective.
- Watch Jin Seon-kyu in Extreme Job. He goes from a terrifying gangster in The Outlaws to a hilarious, bumbling undercover cop. It’s night and day.
- Check out Yoon Kye-sang in his older dramas like The Greatest Love. You won't believe it's the same guy who was hacking people up in Garibong.
- Look for Ma Dong-seok in Train to Busan. It’s the role that made him a global star, and you can see the seeds of his "Seok-do" character being planted there.
The cast of the outlaws movie basically created a new archetype for the Korean hero. We don't want the perfect, handsome detective anymore. We want the guy who’s a bit messy, eats a lot of noodles, and can end a gang war with a single open-handed strike.
If you're planning a rewatch, pay attention to the background characters—the local shop owners and the "small-time" thugs. Many of them are played by veteran stage actors who bring a level of realism you don't usually see in big-budget action flicks. That's the secret sauce. It makes the world feel lived-in. It makes the stakes feel real.
Keep an eye out for the latest sequels, as Ma Dong-seok has hinted he wants to keep playing this character until he literally can't throw a punch anymore. Given his current gym routine, that won't be anytime soon.
