Blaxploitation movies deserve a good spoofing, and Undercover Brother tweaks the subgenre with a few good laughs. But what might have been an Afro-centric Austin Powers (adapted by John Ridley from his Internet film series) is instead a lackluster comedy with one basic joke: "Whitey"--personified as a faceless corporate despot known as "the Man"--has the power, but black folks have soul . With enough funk to make Shaft look passé, Eddie Griffin plays "U.B." with … mehran oversized 'fro and a firm grasp of comedic possibilities. He's recruited by the B.R.O.T.H.E.R.H.O.O.D. (an all-black justice league) to foil the Man's plan to derail a Colin Powell-like presidential candidate (Billy Dee Williams), and U.B.'s undercover exploits keep the slim plot moving. Denise Richards and Neil Patrick Harris are gamely ridiculed as token white allies, and it's all in good fun as director Malcolm D. Lee (Spike's cousin) finds room for mild jolts of relevant social commentary. --Jeff Shannon weniger
