Ryu Seung-soo

Ryu Seung-soo (born August 12, 1971) is a South Korean actor. Ryu made his acting debut in 1997 with a minor role in Park Chan-wook's film Trio, and has been active as a supporting actor on film and television since. Among his notable films are the monks-versus-gangsters comedy Hi! Dharma! (2001), "kimchi" western The Good, the Bad, the Weird (2008), and Korean War movie The Front Line (2011). He also appeared on TV in the quirky series Evasive Inquiry Agency (also known as Four Gold Chasers, 2007), revenge drama The Chaser (2012), and power-struggle saga Empire of Gold (2013).

Despite being one of his earliest projects, the 2002 melodrama Winter Sonata is among Ryu's better known roles outside Korea, given the series' popularity throughout Asia. In 2009, he reprised his character via voice acting in the animated adaptation Winter Sonata Anime.

Ryu wrote his memoir Don't Be an Actor Like Me, which was published in 2009.
