Back in October we rolled out photos from "Cadillac Records" of Mos Def and Beyonce as 1950s legends Chuck Berry and Etta James, respectively, and now we've got another first look in the form of a brand new clip. In the scene below, Chuck/Mos tries to convince a skeptical club operator that he is, in fact, the Chuck Berry.

"Cadillac Records" -- in theaters December 5th -- follows the rise of Chess Records and its founder Leonard Chess, and features a laundry-list of celebrities on its casting roster, including the aforementioned Mos and Beyonce, as well as Adrien Brody, Gabrielle Union and more. Click here to watch the clip in high-definition.

Any film that has stars like Beyonce, Columbus Short and Mos Def strapping on 1950's duds is gonna be worth checking out, and "Cadillac Records" is no exception. With a huge cast that includes folks like Adrian Brody and Gabrielle Union, "Cadillac Records" chronicles the real-life rise of Chess Records and its founder Leonard Chess.

Below, check out Mos as legendary artist Chuck Berry and then after the jump check out Beyonce looking sexy as Etta James. Click here or on either photo to check out our full "Cadillac Records" gallery.

If there's one thing I've learned about the glorious IMDB over the years, it's take what's listed in the future with an ample grain of salt. Sometimes the only way to find out if a star is indeed attached or not is to go straight to them and that's what our own Sway did with Rihanna here.

She's been rumored for a while to be making her acting debut in something called "Mama Black Widow." IMDB says it stars her alongside Mos Def but as you can see from the video below we're going to have to wait a little while longer for her big screen debut.
