Although I mentioned it in passing last week when I broke the news that Gabrielle Union would play Geneva Wade in 'Cadillac Records', I should have paid more attention and realized that Chuck Berry is too big of a name to give it little respect.

Feeding off my story, most of the trades are now confirming that Mos Def will play Chuck Berry in the film as well.

With the addition of Jeffrey Wright as Muddy Waters, and Beyonce Knowles as Etta James, this film will either be a hit or a joke. They better do justice to these legendary individuals.
