Oldboy (Hangul: 올드보이; RR: Oldeuboi; MR: Oldŭboi) is a 2003 South Korean mystery thriller neo-noir film directed by Park Chan-wook. It is based on the Japanese manga of the same name written by Nobuaki Minegishi and Garon Tsuchiya. Oldboy is the second installment of The Vengeance Trilogy, preceded by Sympathy for Mr. Vengeance and followed by Sympathy for Lady Vengeance.
The film follows the story of Oh Dae-su, who is locked in a hotel room for 15 years without knowing the identity of his captor or his captor’s motives. When he is finally released, Dae-su finds himself still trapped in a web of conspiracy and violence. His own quest for vengeance becomes tied in with romance when he falls in love with an attractive young female sushi chef.
The film won the Grand Prix at the 2004 Cannes Film Festival and high praise from the President of the Jury, director Quentin Tarantino. Critically, the film has been well received in the United States, with an 80% “Certified Fresh” rating at Rotten Tomatoes. Film critic Roger Ebert claimed that Oldboy is a “powerful film not because of what it depicts, but because of the depths of the human heart which it strips bare”. In 2008 voters on CNN named it one of the ten best Asian films ever made.
