Rascal FlattsRascal Flatts were the subject of an episode of the popular television series, 'CSI: Crime Scene Investigation,' earlier this year. They had such a good time playing themselves that they're going to try their hand at new roles again this fall.

"We're going to do a miniseries on HBO, called 'To Appomattox'," lead singer Gary LeVox explains. "It was a battle in the Civil War, so we're looking forward to that. They want us on 'The Office' and to give us our own show and shoot a major motion picture," he adds with a smile.

The battle at Appomattox, Va., effectively ended the Civil War, as General Robert E. Lee surrendered to General Ulysses S. Grant.

Rascal Flatts' member Jay DeMarcus reveals the reason the trio is in such high demand as actors: "People were really surprised and moved that we played ourselves so well [on CSI]," he says. "That's what really won them over."

But Gary disagrees: "The black eye, I think, is what sold the whole deal," he insists, referring to a scene in the show.

Their guest-starring roles on 'CSI' was not the band's first foray into television and film. In 2006, the guys appeared in an episode of 'Yes Dear' and made a cameo in 2009's 'Hannah Montana: The Movie.' Rascal Flatts also have appeared on the soundtracks for Disney's 'Cars' and 'The Emperor's New Groove.'

Their next appearance will take place on stage as they kick off their Nothing Like This tour in Raleigh, N.C., on June 25.
