Director-choreographer Adam Shankman's screen adaptation of the smash Broadway musical based on John Waters' 1987 crossover movie is a faithful record of the stage version, but thats all it is -- a recording. The story remains the same: In the early 1960s, a plus-sized Baltimore teen named Tracy Turnblad (here played by perky newcomer Nikki Blonsky) becomes an unlikely instigator of integration on an American Bandstand-like TV show. The songs -- clever, up-tempo numbers styled by composer-lyricist Marc Shaiman and co-lyricist Scott Wittman after the Top 40 hits of the era -- are among the best of recent Broadway vintage. But Shankman hasn't reshaped the material in cinematic terms, and the result is a largely lifeless endeavor, lacking both the rambunctious energy of a live performance and the expressionistic pull of the great movie musicals. The stunt casting of John Travolta as Tracys plus-plus-sized mom, Edna, seemed a sound idea, but the dandyish star is oddly restrained in a part that calls for the grandiose. The only real flashes of inspiration here exist on the periphery, especially in James Marsden's performance as the movie's Dick Clark surrogate: Sporting enough Brylcreem to deflect most forms of nuclear radiation and flashing a Pepsodent smile that could guide ships to shore in a raging monsoon, it's Marsden who seems the epitome of the virginal 1950s innocence to which Hairspray is, ultimately, a cockeyed adieu.
