The Cat in the Hat is a marketing ploy disguised as a wildly designed movie for hyperactive kids, and it could use a dose of Ritalin. It hardly matters, though, because kids will surely enjoy the rampant romp that occurs when the top-hatted feline convinces young Sally (Dakota Fanning) and Conrad (Spencer Breslin) to wreak havoc in the home their mother (Kelly Preston) has neatly prepared for an upcoming party. It's all in the name of fun, and while Seuss's classic rhymes are relegated to voice-over narration, director Bo Welch capitalizes on his background as one of Hollywood's most gifted production designers (with credits including Edward Scissorhands and Men in Black), turning the Seussian town of "Anville" into a playful pastiche of pastels. As played by Mike Myers under layers of fur and latex, Dr. Seuss's mischievous Cat is mayhem personified, and the movie suffers from his anything-goes approach to getting a laugh. And though Myers delivers a few laughs while channeling voices from his own comedic repertoire (including "Coffee Talk" maven Linda Richman), a little of this Cat goes a long way, and he nearly wears out his welcome. --Jeff Shannon
