John Legend and Isaac Hayes have joined Jennifer Coolidge, Samuel L. Jackson and Bernie Mac in Malcolm Lee's comedy "Soul Men" for Dimension Films.

Affion Crockett, Adam Herschman, Fatso Fasano and Jackie Long are also joining the feature about two former bandmates (Jackson and Mac) forced to reunite when a third member (Legend) passes away. The pair fight with each other all the way across the country when they're forced to take a road trip together for a reunion concert.

"Soul" marks a return to the big screen for former "South Park" voice star Hayes, who plays himself. The veteran soul singer suffered a stroke in 2006.

Longtime Christopher Guest ensemble member Coolidge ("For Your Consideration") plays Mac's love interest. Former "Will & Grace" star Sean Hayes plays the band's obnoxious manager.

The film, written by Robert Ramsey and Matthew Stone, is now shooting in Shreveport, Memphis and Los Angeles. Producers David T. Friendly, Charles Castaldi and Steve Greener are aiming for an October theatrical release through MGM.
