In which film did Beyoncé play the blues singer Etta James?

Beyoncé played blues singer Etta James in the 2008 film Cadillac Records.

The biographical drama follows the rise of Chess Records and its influential artists, including Muddy Waters, Little Walter, Chuck Berry, Howlin’ Wolf, and Etta James. Beyoncé’s performance portrayed James during a period when the singer was recording for Chess Records.

For the film, Beyoncé recorded versions of several songs associated with James, including “At Last.” Her interpretation helped introduce James’s repertoire to many viewers who knew Beyoncé primarily as a pop and R&B artist.

Cadillac Records is sometimes confused with Dreamgirls, another music-centered film in which Beyoncé appeared. Dreamgirls is a fictional story inspired partly by Motown history, while Cadillac Records is a dramatized account of the Chess Records scene and features Beyoncé as a real historical musician.
