As if they haven't displayed enough talent in their diverse performances, SAMUEL L. JACKSON and BERNIE MAC are now singing and dancing together in their new movie -- and ET's KEVIN FRAZIER has an exclusive first look!

In 'Soul Men,' in theaters October 10, Sam and Bernie play a pair of backup soul singers who haven't spoken to each other in 20 years. But when they're invited to perform at a tribute concert for their famous former band leader, the two curmudgeons reluctantly agree to travel cross country together for the honor.

"We battle the whole film," says Bernie on the Mojave Desert set. "The battle wasn't with malice or anything like that; it's just two different personalities just clashing, and generally we love each other."

"Like all groups," adds Sam.

No "stunt doubles" were used in the making of the entertaining comedy -- both Sam and Bernie do their own musical and dance performances in the film!

"Like anything, if you don't use it you lose it; we can hold a note," says Bernie.

"Yeah, we're melodious," adds Sam with a wink. "When you hear the soundtrack, you'll see. We'll be at the Grammys next year."
