Oldboy

Often cited as one of the best films of the 2000s and possibly the definitive example of extreme Asian cinema, Oldboy is a brutal, lyrical modern classic of the revenge genre. Based on the Japanese manga of the same name, the film tells the horrific tale of Oh Dae-su (Choi Min-sik), a businessman who is inexplicably kidnapped and imprisoned in a grim hotel room-like cell for 15 years, without knowing his captor or the reason for his incarceration. Eventually released, he learns of his wife's murder and embarks on a quest for revenge whilst also striking up a romance with a young, attractive sushi chef, Mi-do (Kang Hye-jung). He eventually finds his tormentor, but their final encounter will yield yet more unimaginable horrors...
