While his Hendrick Motorsports teammates were hitting the Daytona pavement testing their stock cars, Jimmie Johnson and Chad Knaus were hitting the big screen at Atlanta Motor Speedway today, filming an upcoming episode of the hit NBC TV series "Las Vegas."

Johnson, playing himself, starred with Nikki Cox, who gets driving tips from a winner at Las Vegas Motor Speedway. Knaus, Johnson's crew chief, also plays himself in the episode which is tentatively set to air on February 6.

While Johnson may seem like a natural on the track, he admits acting isn't quite so easy for him.

"You have a writer trying to write things that you would say and you have to make it sound like what you would say," the driver of the No. 48 Lowe's Chevrolet said.

"Fortunately, I am playing myself, so I can turn to the writers and say 'I would do it like this,' and they are OK with that."

Johnson also admits that it could be even more difficult for him.

"Remembering the lines and trying to look like you're not thinking about the lines that you have to deliver is the most difficult part," Johnson commented. "If I was playing someone else and there was a particular way I had to deliver lines and have a certain personality, I would be in big trouble."

Johnson will return to AMS for the Golden Corral 500 on March 19. For tickets to the March 17-19 race weekend, call (877) 9-AMS-TIX, (770) 946-4211.
