Cameo TV role for Johnson.

While several of his Hendrick Motorsports teammates were busy pounding the pavement during the second week of pre-season testing at Daytona, Jimmie Johnson was busy hitting the big screen thanks to a role in the NBC television series 'Las Vegas.'

Playing himself, Johnson was filming at the Atlanta Motor Speedway along with his #48 Lowe's crew chief Chad Knaus, who also has a cameo role in an episode that is set to air in the United States on February 6th.

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," said Johnson. "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."
