OLD BOY (2003)
Director: Chan-hook, Park
Main Character: Dae-su, Oh

Dae-Su is kidnapped and thrown into a locked room with no windows and only a television set for company. As the weeks turn into months, he works out, trains himself and tries to find a way out of his cell, slowly going insane in the process, especially after learning that he has been framed for his wife's murder while imprisoned.

He tries to kill himself on several occasions, but when he gets too out of control (or just needs a shave and haircut), he is gassed unconscious by his unknown captors.

Oh Dae-Su occupies his time with teaching himself to fight, shadowboxing in his room and exercising to keep himself in shape.

The acting is excellent all round, but the character of Oh Dae-su, played by Choi Min-sik.

In a pivotal fight scene, Dae-Su fights his way through a hallway full of gangsters armed only with a hammer, which Park shoots with a single camera following him from one end to the other without a single edit.This shows his strong body and mind and shows perfect character in this movie.
