This savagely original 2003 thriller from South Korea features a bizarrely intriguing premise. Ordinary family man Dae-su Oh (the intense Min-sik Choi from previous hits Shiri and Tae Guk Gi: The Brotherhood of War) is kidnapped one day and locked in a secret private prison. For 15 years, he's stuck there, unable to even talk to another human being. One day, out of the blue, he is set free. Having trained his body to become a rock-hard killing machine, our hero sets out to discover who imprisoned him and why. Innovatively shot, sympathetically acted and filled with crazy cool energy. Based on the Japanese comic book of the same name. And soon to be remade by Spike Lee. In Korean with English subtitles.
