Kwon Sang-woo
As Yoo's career established itself he began to appear in many high-profile projects, such as in well-known arthouse director Hong Sang-soo's "Woman is the Future of Man" (which, like "Oldboy", screened at Cannes in 2004); Yim Pil-sung's big-budget "Antarctic Journal", shot in New Zealand; and the action/noir "Running Wild" with Kwon Sang-woo. He also established his own production company Yoo Movie in 2005.
