Welcome to the jungle, Smackdown-style. The Rock plays a crime kingpin's unwilling enforcer, assigned to track down the boss' treasure-hunting son (Seann William Scott) in the Amazon to pay off a debt. His mark is clever, but the king of this jungle is a money-hungry, gun-toting slave driver (yet another quirky role for Christopher Walken), and there's danger from rebels and humping monkeys around every tree. Yeah, it sounds like a thinly veiled excuse to show the ex-pro wrestler kicking ass and blowing things up, but this thing actually works. The flick moves quickly, there's Rock-solid action and--okay, we'll say it--body-slamming laughs thanks to the duo's zinging chemistry. It's easily the most fun you'll have with horny monkeys all year.
