Fan-Favorite “Villain” Actor Reveals The Most Chilling Effects He Experienced After Such Intense Roles

Actor Park Sung Woong, well-praised for his most convincing portrayals of notoriously villainous roles, surprised his fans after revealing the psychological aftereffects he experienced from playing such roles.

In the March 26, 2026 (KST) episode of Problem Child In House, the actor opened up about his role as a serial killer in a movie from over a decade ago—and how it took a real toll on him.

About 11 years ago, I played a serial killer in the film The Deal. After filming a particularly intense scene, I suddenly found myself sitting in front of a blank TV screen… but I had no memory of how I got there.

He also brought up his role in the 2020 K-Drama Rugal, explaining how deeply he immersed himself in the character. And somewhere between cutting carbs to fit the role and pouring out all he had on set, the actor said it really tipped him over the edge, leaving him with alarming, intrusive thoughts.

I went too intense with it—shooting people, stabbing them, screaming like I’d lost my mind. I also had shirtless scenes, so I cut out carbs, which made me extremely sensitive. It got to the point where I went to the hospital on my own.

I was worried I might hurt someone, so I put away all the knives in the house.

Then, one day, I was driving on the highway with my son, and I kept having the urge to jerk the steering wheel. I thought if I held it normally, I might actually turn it, so I drove gripping it with just my fingers.

Park Sung Woong shared that he ultimately overcame these chilling aftereffects through exercise.
