Eddie Murphy, Jennifer Hudson and Beyoncé Knowles blow the roof off the joint with their performances in this slick, highly entertaining screen adaptation of the Broadway show. Murphy and Oscar-winner Hudson star as a James Brown-like fading star and an ostracized girl-group singer, respectively. Loosely based on the rise of The Supremes and Motown, the movie might lack depth, but quite honestly, it doesnt really need it. This show is about the music and the performances, and both are first rate. Its so nice to see Murphy putting his talents to work in a film that deserves him rather than the silly, sometimes-amusing stuff hes been turning out for the last 24 years. While he and Hudson are getting all of the hype, Knowles shouldnt be overlooked for her fine work. Her role calls for her voice to be somewhat repressed, but she lets us have it late in the film with a number that shows off her stuff.
