Ahn Sung-ki
In Ryoo Seung-wan's "Arahan", he played a hapless traffic policeman who discovers he has untapped martial arts potential, as he's trained by masters played by Ahn Sung-ki and Yoon So-yi. Part modern-day wuxia, part superhero film and part local comedy, it was Ryoo Seung-wan's first foray into commercial cinema, and the film was a relative box office success at around 2 million tickets sold. It also established Ryoo's star charisma and his natural affinity for comedy.
