Oldboy

Oldboy (Korean: 올드보이) is a 2003 South Korean action thriller film directed and co-written by Park Chan-wook. A loose adaptation of the Japanese manga Old Boy by Garon Tsuchiya and Nobuaki Minegishi, the film follows Oh Dae-su (Choi Min-sik), who is imprisoned for 15 years without knowing the identity of his captor or his captor's motives. When he is released, Dae-su finds himself trapped in a web of conspiracy and violence as he seeks revenge against his captor and 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.
