Beyonce vs. Aguilera, Dion and more

Beyoncé returns to big screen movies with big soundtracks in the latest biopic "Cadillac Records."

The film is slated for a December release and chronicles record executive Leonard Chess, played by Adrien Brody, and his Chicago-based music label. Chess is the svengali behind such 1950s/60s artists as Muddy Waters, Bo Diddley and Etta James--Beyoncé's role. The film is also executive produced by Beyonce who will also perform the Etta James classic "At Last" on the soundtrack.

Beyoncé's recent Fashion Rocks performance of the cover song staple was lackluster at best. Previously Celine Dion, Christina Aguilera, Lou Rawls, Stevie Nicks, Stevie Wonder, Joni Mitchell--and the list gets longer--have all covered the song.
