So there have been quite a few movies based on racing....Days of Thunder, Cars, Cannonball Run, Stroker Ace, etc. But my favorite has to be Talladega Nights. The best part of that movie to me was the reference to the Highlander movie (another favorite movie of mine that is not at all racing related). That, and all the one-liners to come out of that movie.
