With its realistic violence and cringe-inducing themes, the South Koren revenge film "Old Boy" isn't for sissies. Drunken cad, Oh Dae-Su is kidnapped and locked up for 15 years. He's drugged throughout his captivity, and the audience is privy to his vivid hallucinations.
When he's set free, Oh Dae-Su swears revenge on his captor, soon discovering that he's the victim of a man named Woo-jin's own monstrous revenge plot. I can't tell you why this movie is so sick without ruining one of the twists, but I promise that you will gasp and/or hold your hand over your mouth at least once during the film.
This Cannes Film Grand Prix winner is loosely based on a manga, and I could see the influence. In one scene, Dae-Su uses his hammer to beat down about 20 thugs in a narrow ally. This super-human feet is shown so hyper real, that it's actually believable. "Old Boy" swings from these instances of urgent brutality to dizzy, point-of-view trances, keeping you guessing all the way to it's queasy culmination.
