Acting in a k-drama can be dangerous. Demanding production schedules that often require filming through the night can lead to fatigue and easily preventable accidents. And an actor's dedication can cause them to ignore their own limits.

This week Seo In Guk was rushed to the hospital after he injured his eye while rehearsing an action scene for his upcoming drama "The King's Face." He was practicing at an action school when a stuntman accidentally hit him in the face. Seo In Guk's eye began to ache and swell so he went to the hospital for treatment.

Seo's eye injury is not considered very serious so it is not expected to interfere with the shooting schedule of the drama, which also stars Lee Sung Jae and Jo Yoon Hee. The drama is expected to premiere on schedule in November.

While Seo was filming "High School King Of Manners," he injured his shoulder ligament while filming a training scene and had to wear a cast. The writers wrote his injury into the plot.

It's the second time this week that an actor was rushed to the hospital while preparing for a drama. Park Hae Jin was taken to the hospital suffering from fatigue while filming the upcoming drama "Bad Guys." He had been filming for six days straight without resting. He wanted to return to the set, saying it was not right for him to rest when the rest of the cast could not.

Nor are these cases isolated ones.

JYJ's Park Yoochun filmed the action thriller "Three Days" while in pain. He tore his shoulder ligament while filming an action scene. It was his first drama with action scenes so being a very serious and dedicated actor, he may have pushed himself too hard. Instead of resting, as his doctors advised, he kept filming.

Lee Seung Gi sustained an eye injury earlier this year when he was filming an action scene with a prop knife. The "You're All Surrounded" actor injured his cornea and the drama had to suspend filming. The injury limited his range of motion.

Last year Moon Geun Young suffered an eye injury during the filming of "Goddess of Fire: Jeonji." Her eye became swollen and she had to go to the emergency room. She had to rest for a few days until the swelling went down. On a previous drama set she broke her nose and on another she twisted her ankle.

Kim Nam Gil also has more than one on-set injury to his credit. While filming "Shark" he cracked his ribs but returned to work anyway.
