Directed by Chan-wook Park, starring Choi Min-Sik, Ji-Tae Yu, Hye-Jeong Kang, Dae-Han Ji, Dai-Su Oh, Byeong-Ok Kim and Gwang-Ok Oh.

Office worker Oh Dae-Su (Choi) goes on a bender, is brought to the local police station and afterwards imprisoned - but not by the forces of law and order. Someone else has taken Oh's freedom and put him in a cell that looks like a room from a rundown 1970s B&B. With a TV for company, Oh learns that he is the missing suspect in his wife's death and then has 15 years inside his kitschy abode to get used to the news. He toughens his brain, with the TV, and his body, by using the walls as a punchbag, and swears vengeance on whoever has locked him up. Then one day, he gets out. He's given some cool clothes, a phone and cash and told he has three days to unravel the mystery of what happened to him.

It begins with one man grabbing hold of another as he hangs off the side of a building with his dog, and 'Oldboy' never lets up in its bid to be crazy and genius all at once. It's a thriller, a love story, a comedy and a whodunit, all filtered through the unhinged mind of a man whose haircut gives Christopher Walken's some serious competition. It's got nasty scenes (the eating of a live octopus), tender scenes (Oh's romance with the woman who befriends him) and breathtaking scenes (a fight involving Oh and countless heavies that looks like the greatest video game never made), and as each one passes you'll become more and more convinced that this film was one seriously worthy winner at Cannes.

Fans of Spike Jonze's 'Being John Malkovich', David Fincher's 'The Game' and John Boorman's 'Point Blank' are in for one big treat as 'Oldboy' references all three, along with 'Edward Scissorhands', 'The X-Files' and countless others. But these are tributes not takeoffs, because this film is out on its own, a cult in the making that you'll be only too happy to spread the word about. That is if you can speak after the final twist.

Very weird, but very cool.
