"Once upon a time, there was a little ogre named Shrek...." And thus begins the tale of an unlikely hero who finds himself on a life-changing journey alongside a wisecracking Donkey and a feisty princess who resists her rescue. Throw in a short-tempered bad guy, a cookie with an attitude and over a dozen other fairy tale misfits, and you've got the kind of mess that calls for a real hero. Luckily, there's one on hand ... and his name is Shrek.
