Actor Park Yoochun will be showing off his Taekwondo skills in SBS drama "Three Days."

On the 25th the drama's production company Golden Thumb Pictures unveiled photos of Park Yoo Chun in the role of president bodyguard Han Tae Kyung on set.

Park Yoochun is seen wearing uniform as a black belt Taekwondo master. His intense eyes and actions are eye-catching.

Word has it that Park Yoochun went above and beyond just looking the part. He smashed pine boards and demonstrated impressive kicking, receiving the crew's applause on set.

Previously Park Yoochun was also praised for a large-scale scene that took place inside a train, in which he fought 10 to 1. He didn't choose to use a stunt double, but actually acted the scenes out himself. He has now established himself as an action actor.

A Golden Thumb Pictures rep stated, "Park Yoochun has injured his right shoulder, but he takes the lead every time we have an action scene shoot. He gives peace of mind to the cast and crew members that are concerned for him, and his initiative is met with applause. We believe that his transformation into a Taekwondo master will become another one of his better known action scenes."
