Yoo Yun Suk

Yoo Yeon Seok is a South Korean actor under King Kong by Starship. In his junior year in high school, he decided to take up acting, so he followed his brother, who was studying another year to enter university, to Seoul and they lived together.

While taking acting classes, the high schooler met a friend who would later work on the costume staff of film director Park Chan Wook. Remembering that he resembled actor Yoo Ji Tae, she gave him a call about auditioning for a role. So without having to pass out his resume, he made his acting debut as Yoo's younger counterpart in the acclaimed 2003 film Oldboy. 

Upon graduation from Sejong University with a degree in Film Arts, he resumed his acting career in 2008. He served in the Air Force and was discharged in 2007. At his agency's recommendation, he began using the stage name Yoo Yeon Seok, dropping his birth surname Ahn. Yoo received his best reviews yet for playing a sensitive ex-boyfriend searching for his child in the indie film Re-encounter. 

Soon after, he became known to mainstream audiences as the rich and spoiled antagonist in the box office hit melodramas Architecture 101 and A Werewolf Boy. He further raised his profile in 2013, with the comedy film Born to Sing.
