Yoo's directorial debut "Mai Ratima" clinched the Jury Prize, the second top honor, at the 2013 Deauville Asian Film Festival in France.Von Trier's new movie, which comes out next year, follows a character named "Jack" becoming a serial killer over the course of 12 years. It stars Matt Dillon, Uma Thurman and Riley Keough.
"It is an honor to appear in a film by Lars von Trier, who is one of my favorite filmmakers. Despite it being a cameo role, it was a special and valuable experience," said Yoo, who became the first Asian actor ever to appear in a movie by Trier.
