LOS ANGELES (Hollywood Reporter) - Rapper-actor Mos Def will play legendary rock 'n' roller Chuck Berry in "Cadillac Records," which is filming in New Jersey.
Also joining the cast is Gabrielle Union, who will play Geneva Wade, a girlfriend of Muddy Waters.
The Sony BMG film is set in 1950s Chicago and follows the turbulent lives of Chess Records co-founder Leonard Chess (Adrien Brody), and the label's artists, including Waters (Jeffrey Wright), Little Walter (Columbus Short), Howlin' Wolf (Eamonn Walker), Etta James (Beyonce Knowles) and Willie Dixon (Cedric the Entertainer).
Darnell Martin ("Their Eyes Were Watching God") is directing from his own script.
Mos Def was recently in theaters with Michel Gondry's comedy "Be Kind Rewind." Union's credits include ABC's "Ugly Betty" and the upcoming Eddie Murphy comedy "Meet Dave."
