Oldboy is one of the greatest movies ever conceived by a human mind (Chan-wook Park). It's the middle of the trilogy:
Sympathy for Mr. Vengeance (amazing)
Oldboy (fucking perfection)
Sympathy for Lady Vengeance (okay, but kinda boring)
He's actually being tapped to direct a Metal Gear Solid movie...I hate videogame adaptations, but fuck...this guy has class, he might do good with MGS.
