What was the title of Beyoncé's 2008 musical biographical film about singer Etta James?

Beyoncé played singer Etta James in the 2008 musical biographical film Cadillac Records. The movie, written and directed by Darnell Martin, follows the rise of Chess Records and several performers connected with the label.

Adrien Brody plays record executive Leonard Chess, while Jeffrey Wright portrays Muddy Waters and Columbus Short portrays Little Walter. Beyoncé's performance as James includes the song “At Last,” one of the best-known recordings associated with the singer.

Cadillac Records takes some dramatic liberties, as biographical films often do, so it is not a complete documentary history of Chess Records. Beyoncé also recorded music connected with the project and donated her salary from the film to charity. Cadillac Records should not be confused with Dreamgirls, another music-industry film released in 2006, in which Beyoncé played the fictional singer Deena Jones.
