South Korean film "Old Boy" received the Grand Prize at the 57th Cannes Film Festival in France on Saturday.

The movie, directed by Park Chan-wook, is a blood-soaked thriller about a man out for revenge after 15 years of inexplicable imprisonment. Based on a Japanese comic book, the film has attracted 3.3 million viewers at home.

It is the first time that a South Korean movie has been awarded the
Grand Prize, the second highest award at the prestigious film festival. One of South Korea's best-known directors, Im Kwon-taek, won the best director award for "Chihwaseon" in the same film competition in 2002.

U.S. filmmaker Michael Moore won the festival's highest honor of Palme d'Or for "Fahrenheit 9/11," a scathing indictment of White House actions after the Sept 11 attacks.

Fahrenheit 9/11 was the first documentary to win Cannes' prestigious Palme d'Or since Jacques Cousteau and Louis Malle's The Silent World in 1956.
