The romantic comedy "America's Sweethearts" was Zeta-Jones's sole film project of 2001. She starred as a shrewd movie star, opposite Julia Roberts who featured as her character's under-confident sibling. The critic Roger Ebert compared the film unfavourably to the musical "Singin' in the Rain" (1952), but thought that Zeta-Jones was aptly "chilly and manipulative" in her part. The following year, Zeta-Jones starred alongside Renée Zellweger as the murderous nightclub singer Velma Kelly in "Chicago" (2002), a film adaptation of the Broadway musical of the same name from the director Rob Marshall. She based her character's look and mannerisms on the actress Louise Brooks, and as the script did not provide a backstory to Kelly, she worked to convey her character's "flamboyance" and "desperation" through "little looks and nuances". The film and her performance received critical acclaim. William Arnold of the "Seattle Post-Intelligencer" felt that the actress made "a wonderfully statuesque and bitchy saloon goddess", and David Edelstein of "Slate" magazine wrote that she has "a smoldering confidence that takes your mind off her not-always-fluid dancingalthough she's a perfectly fine hoofer, with majestic limbs and a commanding cleavage" and particularly praised her rendition of the song "All That Jazz". "Chicago" earned worldwide, and was the recipient of the Academy Award for Best Picture. For her performance, Zeta-Jones won the Academy Award, SAG Award, and the BAFTA Award for Best Supporting Actress, among other awards and nominations.
