Park Hae-soo: The Life Story Behind Squid Game's Villain
In this post
Park Hae-soo is an actor who spent many years working hard in the theatre before the world knew his name, and then, in a single year, the whole world knew it. In 2021, he played Cho Sang-woo in Squid Game, and his face became familiar to hundreds of millions of people. He played a man who was clever, proud, and desperate, a man who had once been the pride of his neighbourhood and who had fallen into debt and shame. It was not a simple villain role. It was a portrait of a man who makes terrible choices because he believes he has no other choice, and audiences around the world could not look away.
What makes his story interesting is how long the road was before Squid Game. He was not a young star who became famous overnight. He was a theatre actor who sang in musicals, played in small halls, and took small television roles for years. He was already in his mid-thirties when he got his first leading television role, in Prison Playbook, and he was almost forty when Squid Game made him famous around the world. His career is a story of patience, hard work, and being ready when the big moment finally came.
After Squid Game, he did not stop. He played Berlin in Money Heist: Korea, he played a spy in Narco-Saints, and he led The 8 Show on Netflix. He has become one of the Korean actors that the world watches, and he has done it without losing the serious, careful style he learned on the stage. This is the story of how a musical theatre actor from Suwon became one of the most recognisable faces in global television.
Growing Up in Suwon
Park Hae-soo was born on 21 November 1981 in Suwon, a city in Gyeonggi Province in South Korea. Suwon is a large city south of Seoul, known for its old fortress walls and its busy streets, and it was a good place to grow up. He was born into an ordinary family, and there was nothing in his early life that pointed clearly toward fame. He was a normal boy in a normal city, and his dream of acting grew slowly, like it does for many young people.
He has not shared many details about his childhood in public, and he has kept his family life private from the start. What is known is that he became interested in acting while he was young, and that he chose to study it seriously. He went to Dankook University, where he studied theatre and film, and that choice shaped his whole life. University gave him teachers, classmates, and a place to learn the craft properly, instead of simply dreaming about it.
At university, he learned that acting is not only about talent. It is also about discipline, about showing up, about rehearsing until the work is right. He learned how to use his voice, how to move on stage, and how to understand a character from the inside. Those lessons stayed with him, and they are the reason his later performances feel so complete. He does not act on the surface. He acts from deep inside the character.
Suwon also gave him something else, a sense of being an ordinary person. He did not grow up in the centre of Seoul, surrounded by the entertainment industry. He grew up in a city where people worked hard, lived normal lives, and dreamed normal dreams. That background shows in his acting. When he plays a man from a poor neighbourhood, as he did in Squid Game, he understands that man, because he knows what ordinary life feels like.
By the time he finished university, he knew what he wanted. He wanted to act, and he was willing to start at the bottom. He did not expect fame. He expected hard work, and he was ready for it. That attitude would carry him through many years when fame did not come.
The Musical Stage and the Theatre Years
Park Hae-soo began his professional career on the stage, and for many years the theatre was his home. He made his debut in the musical Mister Lobby in 2007, and he went on to perform in many musicals and plays. The theatre world in Korea is small and demanding, and it teaches actors lessons that no other place can teach. He learned those lessons well, and they became the foundation of everything he did later.
Musical theatre is one of the hardest forms of acting. An actor must sing, dance, and act at the same time, and must do it live, in front of an audience that can see every mistake. Park Hae-soo learned to do all of it. He developed a strong voice, a strong stage presence, and the stamina to perform night after night. He also learned how to connect with an audience, how to make people in the back row feel what his character feels. That skill is rare, and it never left him.
He performed in plays as well as musicals, including the play Annapurna, and he became known in the theatre world as a serious and reliable actor. Directors trusted him because he prepared carefully and because he never treated a role as small. Other actors trusted him because he listened on stage and because he gave his full attention to the scene. That kind of trust is built slowly, and it is the kind of trust that follows an actor into television and film.
The theatre years were not rich years. The pay was low, the hours were long, and the audiences were small. But they were rich in another way. They gave him time to learn, time to fail, and time to grow without the pressure of fame. Many actors who become famous young never get that time. Park Hae-soo got it, and he used it well. By the time he moved to television, he was already a complete actor.
What the stage also gave him was a voice that could carry emotion. His voice is deep and clear, and it can be warm or cold, gentle or frightening. In Squid Game, his voice is one of the things that makes Cho Sang-woo so believable. He speaks quietly, and you listen, because the voice tells you that this man is thinking, calculating, and hiding his fear. That is stage training, and it is a gift that keeps working for him.
Small Screen Roles and the Long Wait
Park Hae-soo moved into television slowly, with small roles that gave him experience but little fame. He appeared in dramas in the mid-2010s, including Six Flying Dragons in 2015, where he played a supporting role in a large historical epic. It was good experience, and it showed that he could work in a big production with many stars, but it did not make him famous. He was still a working actor, waiting for his chance.
The wait was long, and it tested his patience. He was in his thirties, an age when many actors have already become stars, and he was still taking supporting roles. He did not give up. He kept working in the theatre, kept taking television roles, and kept improving. He believed that if he kept doing good work, the right role would come. That belief is easy to hold for a year, and hard to hold for ten years. He held it for ten years.
During this time, he also appeared in films in small roles, learning how the camera worked and how film acting differed from stage acting. On stage, he had learned to reach the back row. On film, he had to learn to trust the camera to come close to him. He learned to do less with his body and more with his eyes. He learned that a small change in the face could say more than a long speech. These were not easy lessons, but he learned them well.
He also learned how to wait without becoming bitter. That is one of the hardest lessons in any career. Many actors become angry when fame does not come, and that anger shows in their work. Park Hae-soo did not become angry. He stayed focused, stayed kind to the people he worked with, and stayed ready. When the big chance finally came, he was ready because he had never stopped preparing.
By 2017, he was thirty-six years old, and he had spent a decade in the theatre and on television. He had the craft, the experience, and the patience. What he needed was a leading role that would show the world what he could do. That role came in Prison Playbook, and it changed his life.
Prison Playbook and the First Big Break
In 2017, Park Hae-soo got his first leading television role in Prison Playbook, a drama about a star baseball player who goes to prison. He played Kim Je-hyuk, a famous pitcher who is sent to prison after an incident, and who must learn how to live in a world that is completely different from the one he knew. The role was perfect for him, because it asked him to play a man who is strong on the outside and lost on the inside.
The drama was a success, and his performance was praised by critics and audiences alike. He played Kim Je-hyuk with warmth and humour, and he made the character feel real. The audience believed in him as a baseball star, and they believed in him as a man trying to survive in prison. He showed that he could carry a whole series on his shoulders, and that he could make people care about a character for sixteen episodes.
Prison Playbook also showed his range. The drama was funny and sad at the same time, and he moved between the two without effort. In one scene, he was joking with his fellow prisoners. In the next, he was facing the pain of his situation. That ability to hold both feelings at once is the mark of a good actor, and it is one of the things that made the drama so loved.
After Prison Playbook, his career changed. He was no longer a supporting actor. He was a leading man, and directors wanted him for bigger roles. He was offered film roles, including a part in the Netflix film Time to Hunt in 2020, and he was offered more television work. He chose carefully, and he continued to work in the theatre as well, because the stage was still his home.
The success of Prison Playbook also proved something important. It proved that a late start is not a failed start. He was thirty-six when he got his first leading role, and he was ready for it because he had spent ten years learning. That is a lesson that many people need to hear, in acting and in any other work. The years that look slow are often the years that prepare you.
Squid Game and Becoming Famous Around the World
In 2021, Park Hae-soo starred in Squid Game, and his life changed completely. He played Cho Sang-woo, a man who had once been the pride of his neighbourhood, a top student who went to a famous university and became a successful businessman, and who had then fallen into debt and disgrace. Sang-woo joins a deadly game in the hope of winning a huge prize, and he is willing to do terrible things to win it. It was a complex and difficult role, and Park Hae-soo played it brilliantly.
The series became a global phenomenon. It was watched by hundreds of millions of people around the world, and it became the most-watched series in Netflix history at the time. Park Hae-soo’s face became known in countries he had never visited, and his performance was discussed by critics everywhere. He was nominated for major honours, including an Emmy Award for Outstanding Supporting Actor, which was a rare achievement for a Korean actor at the time.
What made his performance so powerful was that he did not play Sang-woo as a simple villain. He played him as a man who believed he had no choice. Sang-woo was clever, proud, and afraid, and he made terrible decisions because he could not face his shame. Park Hae-soo showed all of that in his face, in his voice, and in his silences. Audiences hated what Sang-woo did, but they understood why he did it, and that understanding made the character unforgettable.
The success of Squid Game also changed Korean entertainment. It showed the world that Korean stories could be watched and loved everywhere, and it opened doors for many Korean actors. Park Hae-soo was one of the actors who walked through those doors. He became a global star, and he did it with a performance that was serious, careful, and deeply human.
It is worth remembering that he was almost forty when Squid Game made him famous around the world. He had spent fourteen years in the theatre and on television before that moment. When the world finally saw him, he was ready, because he had spent all those years getting ready. That is the story of his career in one sentence.
Money Heist, Narco-Saints, and Life After Squid Game
After Squid Game, Park Hae-soo could have taken any role he wanted, and he chose carefully. In 2022, he played Berlin in Money Heist: Korea, the Korean version of the famous Spanish series. Berlin was a different kind of character from Sang-woo. He was charming, dangerous, and theatrical, and Park Hae-soo played him with a smile that hid his cruelty. The series was watched around the world, and it showed that he could lead another major global project.
In the same year, he starred in Narco-Saints, a Netflix series about a man caught between drug dealers and the intelligence service in Suriname. He played Choi Chang-ho, a government agent, and the role asked him to be quiet, careful, and watchful. It was a different kind of acting from Money Heist, and it showed his range. He could be loud and charming in one series, and quiet and tense in another, and both felt true.
In 2024, he led The 8 Show, a Netflix series about eight people trapped in a strange building where time is money. He played Bae Jin-su, a man in debt who joins the show in the hope of escaping his life. The series was dark and strange, and his performance held it together. He showed again that he is at his best when he plays a man under pressure, a man who must make hard choices and live with them.
He has also appeared in films, including the film Yadang: The Snitch in 2025, continuing to work in cinema as well as in streaming series. His career has moved with the times, from the stage to television to the global streaming screen, and he has stayed relevant in each one. That is not easy, and it is a sign of how adaptable he is as an actor.
Through all of this, he has kept the same careful style he learned on the stage. He prepares deeply, he listens to other actors, and he gives every role his full attention. Directors who work with him praise his discipline, and other actors praise his kindness. He has become a star, but he has not become a difficult star. He is still the hard-working theatre actor from Suwon, and that is part of why people love him.
Family, the Stage, and a Career That Keeps Growing
Park Hae-soo married in January 2019, and he and his wife welcomed a son in 2021. He keeps his family life private, and he rarely speaks about it in public. That privacy is part of who he is. He believes that the work should be public and the home should be private, and he has kept that line throughout his career. In a time when many stars share everything online, his quiet approach is unusual, and many people respect him for it.
He has also kept his connection to the theatre, returning to the stage when he can. The theatre is where he learned his craft, and he has never forgotten it. He has said that the stage keeps him honest as an actor, because a live audience will not forgive a false performance. That honesty is visible in all his work, from Prison Playbook to Squid Game to The 8 Show. He does not act for the camera alone. He acts for the people watching, and he wants them to feel something real.
Today, Park Hae-soo is one of the most recognisable Korean actors in the world. His name is known in many countries, and his work is watched by millions. He has achieved something that very few actors achieve. He has become a global star without losing the serious, careful style that made him good in the first place. He is still the actor who prepares deeply, listens carefully, and gives everything to the role.
His place in Korean entertainment is now secure. He is counted among the leading actors of his generation, and younger actors look up to him. He has shown that a career built on patience and hard work can lead to the biggest stages in the world. He has shown that a theatre actor from Suwon can become a star in every country on earth, and that is a remarkable thing.
For audiences, the lesson of his life is simple. Do the work when no one is watching, and be ready when the world finally looks at you. Park Hae-soo did the work for fourteen years before Squid Game, and when the world looked, he was ready. That is why his story matters, and why it will be remembered.
His career also shows that there is no single path to success in acting. Some actors become famous young. Some become famous late. Some come from the stage, and some come from television. What matters is not the path, but the work you do along it. Park Hae-soo did honest work for many years, and the world eventually found him. That is a hopeful message for anyone who is still waiting for their own moment.
My Take:
I have to start with Squid Game, because that is where most people in the world first met Park Hae-soo, and it is where I first saw what he could do. I watched him play Cho Sang-woo, and I felt something complicated, which is rare for me. I did not simply hate him, and I did not simply like him. I understood him, and that understanding made me uncomfortable, because it made me think about what I might do in his place. That is the mark of a great performance. It does not let you sit back and judge from far away. It pulls you close, and it asks you to think.
What I admire most about his performance in Squid Game is that he did not play a villain. He played a man. Sang-woo was clever, proud, and full of shame, and those three things together made him dangerous. I think many actors would have played him as cold and evil, and the character would have been easy to hate and easy to forget. Park Hae-soo played him as a man who was afraid, and that fear made him real. I could see the fear in his eyes, even when he was doing terrible things, and that fear stayed with me long after the series ended.
I also think about the years before Squid Game, because those years tell me more about the man than the fame does. He spent years in musical theatre, singing and dancing and acting in front of small audiences, and he did it without fame and without much money. I find that admirable, because it is easy to work hard when everyone is watching you. It is much harder to work hard when almost no one knows your name. He worked hard anyway, and I respect that more than I can say.
His story also makes me think about age and timing. He was almost forty when the world finally saw him, and he was thirty-six when he got his first leading television role. In a world that tells young people they must succeed by twenty-five, his life says something different. It says that your time may come late, and that is fine, as long as you are ready when it comes. I think many people need to hear that, because many people feel that they are too late, and they give up too soon. Park Hae-soo did not give up, and I am glad he did not.
I want to say something about his theatre background too, because I believe it is the secret of his acting. On stage, you cannot hide behind editing or music. The audience is right there, and they will know if you are not honest. He learned that lesson on stage, and he brought it to television. When I watch him in Squid Game, I can see the stage actor in him. He listens, he pauses, he lets silence do the work, and he trusts the audience to understand. That trust is rare, and it is one of the reasons his performances feel so deep.
Prison Playbook is another performance I think about a lot. He played a baseball star in prison, a man who had everything and lost it, and he played him with warmth and humour. I liked that he did not play the character as a victim. He played him as a man who was trying to live, trying to be kind, and trying to keep his dignity in a hard place. That is a hopeful way to play a character, and I think it shows something about Park Hae-soo himself. He believes that people can keep their dignity even when life is hard, and he brings that belief to his roles.
I also admire the way he chose his roles after Squid Game. He could have taken the easiest path, playing the same kind of character again and again, and making a lot of money. Instead, he chose different roles. Berlin in Money Heist: Korea was charming and dangerous. Choi Chang-ho in Narco-Saints was quiet and watchful. Bae Jin-su in The 8 Show was desperate and trapped. Each one was different, and each one showed a different part of him. I think that takes courage, because it is easier to repeat what worked. He chose to grow instead, and I respect that choice.
His work in Money Heist: Korea also makes me think about how he uses his smile. Berlin smiles a lot, but the smile is not warm. It is a mask, and behind the mask is something cold. Park Hae-soo played that smile perfectly, and it reminded me that a smile can hide many things. I think that is a clever piece of acting, because it uses something simple, a smile, to tell a complex truth about a person. Not every actor can do that. He can, and it is one of the reasons I enjoy watching him.
There is something else I want to mention, and it is his voice. His voice is deep and clear, and it carries weight. When he speaks quietly, I listen, because the voice tells me that the man is thinking. In Squid Game, some of his most powerful moments are the quiet ones, when he says very little and lets his face do the work. I think that is stage training, and it is also a gift. A voice like that cannot be learned in a day. It is built over years of singing and speaking on stage, and it is one of his greatest tools.
I also think about what his success means for Korean actors in general. Squid Game opened doors for many Korean actors, and Park Hae-soo was one of the people who walked through those doors with grace. He did not become loud or arrogant. He kept working, kept choosing good stories, and kept his private life private. I think that is the right way to handle sudden fame. Fame can change people, and it often makes them hungry for more. He seems to have stayed the same man who worked in the theatre, and I admire that steadiness.
His private life also makes me think. He married in 2019, and he became a father in 2021, and he has kept his family out of the public eye. I respect that very much. In a time when many stars share everything online, his privacy feels like a form of dignity. I do not know his family, and I do not need to know them. What I know is that he has kept his work and his home separate, and that is a hard thing to do when you are famous. I think it shows that he knows what matters.
If I had to name one lesson from his life, it would be this: be ready. He spent fourteen years getting ready, and when the big moment came, he was ready. That is not luck. That is preparation meeting opportunity, and it is the oldest lesson in the world. Many people wait for their moment without preparing, and when the moment comes, they are not ready. Park Hae-soo prepared, and that is why his moment became a career instead of a single success.
I also learn from his patience. Ten years in the theatre, ten years in supporting roles, and then a breakthrough at thirty-six. That is a long time to wait, and I am sure there were days when he wondered whether it would ever happen. I do not know his private thoughts, and I will not invent them, but I know what waiting feels like. It can make you bitter, or it can make you quit. He did neither. He kept working, and he kept his craft sharp. I find that quietly heroic, and it makes me want to be more patient in my own life.
Another thing I notice is how he treats other actors. In Squid Game, he was part of a large cast, and he did not try to steal every scene. He played his part, supported the other actors, and made the whole series better. That generosity is rare, and it is one of the reasons directors love working with him. An actor who makes everyone around him better is worth more than an actor who only cares about himself. I think that is a lesson for any kind of work, not just acting.
I also want to say that I enjoy the way he moves between genres. He has done drama, comedy, action, and fantasy, and he has been good in all of them. That is not easy. Many actors find one genre and stay there, because it is safe. He has not stayed safe. He has tried new things, and he has taken risks, and those risks have made his career interesting. I think that is the mark of a true artist, someone who does not stop learning and does not stop growing.
When I think about his future, I feel hopeful. He is still in his forties, and he is still doing strong work. He has the experience of the stage, the fame of Squid Game, and the trust of directors around the world. I believe his best work may still be ahead of him, and I look forward to seeing it. Whatever he does next, I know he will bring his preparation, his honesty, and his hard work to it, and I know I will want to watch it.
I also think his story teaches us about the value of ordinary people. Cho Sang-woo was an ordinary man from an ordinary neighbourhood, and his story became one of the most watched stories in the world. That tells me that ordinary lives matter, and that ordinary struggles are worth telling. Park Hae-soo understands ordinary people, because he is one, and he brings that understanding to his roles. I think that is a beautiful thing, and it is why his work touches so many people.
There is a sadness in his story too, and I do not want to ignore it. The sadness is in the characters he plays, men who make terrible choices because they feel trapped. Sang-woo felt trapped by debt and shame. Bae Jin-su felt trapped by debt and hopelessness. These are real feelings, and many people in the real world feel them too. I think Park Hae-soo plays these men so well because he understands that feeling, and because he treats it with respect instead of judgement. That respect is a kind of kindness, and I admire it.
Finally, I want to say that I am grateful for actors like Park Hae-soo. In a world full of noise, his work is quiet, careful, and honest. He does not shout for attention. He lets the work speak, and the work has spoken to hundreds of millions of people. I think that is the best kind of fame, the kind that is earned slowly and kept quietly. He has earned it, and I believe his work will be watched for many years to come.
I also think about the young people who might read his story and dream of acting. If you are one of them, I hope you learn the right lesson from him. Do not chase fame first. Chase the craft. Learn to sing, learn to act on stage, learn to listen, and learn to wait. Fame may come late, or it may come in a way you do not expect, but if you are ready, it will become a career. Park Hae-soo was ready, and his story proves that the long road can lead to the biggest stage in the world.
The last thing I will say is simple. I like Park Hae-soo because he is honest. He is honest in his acting, honest in his choices, and honest in the way he lives his life. That honesty is rare, and it is precious. I hope he keeps it, and I hope he keeps working for many more years, because the world needs more actors like him.
