*ComingSoon.com is reporting that Jeffrey Wright has been tapped to play blues legend Muddy Waters in the upcoming Sony/BMG film "Cadillac Man."

Written and directed by Darnell Martin ("Their Eyes Were Watching God"), the film follows the rise and fall of Chess Records, which launched the career of Waters as well as Etta James and Chuck Berry.

According to the Web site, Matt Dillon will play Leonard Chess, who co-founded the label with his brother Phil.

While Phil focused on jazz, Leonard Chess honed in on roots music. He traveled the South taking in various blues scenes and selling records from the back of his Cadillac. Leonard went on to make Chess the greatest repository of black music during the 50s and 60s. It was under Chess' tutelage that Muddy Waters' electric blues sparked a revolution that led directly to rock and roll via fellow Chess artist, Chuck Berry.

Filming is set to begin in January in New Jersey and Chicago.
