This charmingly loopy, iconoclastic story about a crotchety ogre (voiced by Mike Myers), an upstart donkey (Eddie Murphy), a princess with a beauty secret (Cameron Diaz), and a contemptible nobleman with a Napoleonic complex (John Lithgow) isn't only a funny, sprightly fable for all ages about not judging a book by its cover; it's also a kind of palace coup, a shout of defiance, and a coming-of-age for DreamWorks, the upstart studio that shepherded the project with such skill and chutzpah.
