Director Lee Byung Hun was a guest on MBC's 'Radio Star' on October 7 when he talked about an episode with Kim Woo Bin while filming his movie, 'Twenty'.

He said, "There was a scene in which he was running to Kang Ha Neul in a karaoke room, but he stepped on a book and slipped and fell. Everyone went crazy. The injury was worse than we thought. There was a joke that I was becoming a traitor to Asia."
