The Lizzie McGuire Movie is similar to the TV program and features the same cast and characters except here Lizzie McGuire (Hilary Duff) and friends leave the confines of Disney's Los Angeles studio headed for a class trip to Italy where you're hit with the preposterous storyline: In Rome Lizzie is mistaken for a famous pop star named Isabella and before long she is asked to impersonate the singer at a huge Italian music award show. Turns out Isabella had agreed to perform at the ceremony but backed out at the last minute leaving her singing partner Paolo (Yani Gellman) in a legal lurch. Lizzie agrees in part because she has a crush on Paolo and spends the rest of the trip prepping for the big night. There are so many things wrong with this ridiculous plot it's tough to know where to begin. The worse part is the Lizzie so many kids relate to on the tube is transformed here into a self-indulgent fashion plate who changes outfits more often than Celine Dion in concert. The result is an obvious promotional tool for the Lizzie McGuire TV phenomena rather than a movie about change growing up and the awkwardness of transitioning from middle school to high school. Sixteen-year-old Duff recently made her big-screen debut in Agent Cody Banks but it was her two-year-old TV series Lizzie McGuire that catapulted her into 'tween idol status. In The Lizzie McGuire Movie Duff who appears in practically every scene bears the whole weight of the movie. That's an impressive feat for such a young actress and Duff does it quite professionally: her character stutters nervously when addressing her middle school graduating class and bites her lips in a kittenish manner when uncertainty sets in. Duff plays to the camera like a pro and knows how to maximize her cutie-pie image for the big screen. It's a shame her relatable Lizzie McGuire character was transformed into such a shallow teenager with very few redeeming qualities. Here's a girl who puts her own interests before that of her friends and gets them to lie for her so she can embark on a romance with a flaky pop star while stealing another one's identity. But Duff is a trooper and grins through it all despite being shrewdly marketed by studio execs like a scented Strawberry Shortcake doll. Director Jim Fall's The Lizzie McGuire Movie is not a movie at all; it's a 90-minute advertisement for Duff. Since the handful of scribes hired to pen this sad script couldn't come up with a quasi-decent storyline Fall resorts to stringing together one montage after another of the ultra-cute teen idol. There's Lizzie singing Blondie's "The Tide is High (Get the Feeling)" in her bedroom while trying on a trillion different little outfits. There's Lizzie on the back of a dragon-red Vespa pointing and gasping at Roman landmarks like the Fontana di Trevi and the Coliseum. There's Lizzie…well you get the picture. The film's shameless self-promotion of its star overshadows any thematic elements and whatever bit of a story it had. And with a full line of Lizzie McGuire apparel and accessories coming soon to a store near you the reasons are all too clear. Sadly the opening screen credits in which Lizzie's animated alter ego spells out names with beauty products including a mascara wand and lipstick are the only entertaining thing about this 'tween pic.
