KEVIN COSTNER

The Oscar winner's group, Modern West, performed a free show at the Santa Fe Rodeo Grounds in New Mexico as a thankyou to extras who showed up to appear in a presidential debate scene in the political comedy.

In the movie, Costner discovered he's the man who can decide the next U.S. President - because the vote comes down to him.

Dennis Hopper and Kelsey Grammer play the presidential rivals.
