Chicago is a 2002 musical black comedy crime film based on the 1975 stage musical, which in turn originated in the 1926 play. It explores the themes of celebrity, scandal, and corruption in Chicago during the Jazz Age. The film stars an ensemble cast led by Renée Zellweger, Catherine Zeta-Jones, and Richard Gere. Chicago centers on Roxie Hart (Zellweger) and Velma Kelly (Zeta-Jones), two murderers who find themselves in jail together awaiting trial in 1920s Chicago. Roxie, a housewife, and Velma, a vaudevillian, fight for the fame that will keep them from the gallows. The film marks the feature directorial debut of Rob Marshall, who also choreographed the film, and was adapted by screenwriter Bill Condon, with music by John Kander and lyrics by Fred Ebb.
