Disney takes another plunge under the sea for its most exciting animated extravaganza in years. No pop-fueled soundtrack. No cute animal sidekicks. No Broadway-bound song-and-dance showstoppers. Instead, Disney's 40th animated feature is a thrilling throwback to the studio's grand tradition of live-action adventures such as 20,000 Leagues Under the Sea. It is also another awesome leap into uncharted realms of the imagination and state-of-the-art animation. (Disney recruited the services of famed comic book artist Mike Mignola to help design the production.) Michael J. Fox heads the voice cast as Milo Thatch, who repairs boilers in a museum basement while yearning to continue his grandfather's quest to find the legendary lost empire of Atlantis. He gets his chance when one of his grandfather's long-lost journals surfaces. An eccentric benefactor (voiced by Frasier's John Mahoney) funds an expedition crewed by a rogues' gallery of colorful characters serving under the imposing Commander Rourke (James Garner). The story may become a bit hard to follow for youngsters once Milo and company reach Atlantis (something to do with an ancient energy source); but they'll get the big picture when Rourke's true nature surfaces, Atlantis is threatened, and mild-mannered Milo gets in touch with his inner Indiana Jones. Atlantis earned a PG rating for its explosive action set-pieces, mildly risqué humor, and provocative character designs (most notably the bombshell Helga, Rourke's right-hand woman). As folksinger Donovan once sang, "Hail, Atlantis!"
