Oldboy (Korean: 올드보이; RR: Oldeuboi; MR: Oldŭboi) is a 2003 South Korean neo-noir action thriller film directed and co-written by Park Chan-wook. A loose adaptation of the Japanese manga of the same name, the film follows the story of Oh Dae-su (Choi Min-sik), who is imprisoned in a cell that resembles 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 as he seeks revenge against the enigmatic Lee Woo-jin (Yoo Ji-tae). His quest becomes tied in with romance when he falls in love with a young sushi chef, Mi-do (Kang Hye-jung). Oldboy attained critical acclaim and accolades worldwide, including winning the Grand Prix at the 2004 Cannes Film Festival, where it garnered high praise from Quentin Tarantino, the president of the jury. In the United States, film critic Roger Ebert stated 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'. The film's action sequences, particularly the single shot corridor fight sequence, also received commendation for their impressive execution. (Source: Wikipedia.org, CC BY-SA)
