This acridly exhilarating adaptation of Bob Fosse's 1975 Broadway musical is an ode to the intertwined glories of sex, showmanship, and lying -- i.e., ''the old razzle-dazzle.'' The heroine, Roxie Hart (Renee Zellweger), is a Kewpie-doll '20s nobody who shoots her lover at point-blank range and ends up on Murderess Row. There, she meets her idol, the vaudeville star Velma Kelly (Catherine Zeta-Jones), as well as Billy Flynn (Richard Gere), a lawyer with corrupt dimples who turns Roxie into a tabloid celebrity. In its caustic high-spirited way, the movie presents us with a vision of women who will do anything to break free of the conventionality imposed by men. Bravado is all -- far more vital than morality -- and the result leaves you thrilled at how good it feels to see life, death, and girl power turned, once again, into a cabaret.
