The 2006 Pixar production was a lullaby to a future generation of potential fans wrapped in a story of friendship and family and a society moving too fast to appreciate any of it. Yes, it was a vehicle to launch a million Christmas purchases, but it also had heart. Amid all the beautiful digital effects was a meticulous attention to minutia both visually and in racing. Cars had to race back onto the lead lap. Lightning McQueen rued not taking tires in the opening sequence. And the film featured voiceover cameos from Mario Andretti, Dale Earnhardt Jr., among many, and made seven-time Sprint Cup champ Richard Petty "Mr. The King" to a generation of children. Not, at least, for years. Last year, Kyle Petty introduced his father by his Cars moniker at his NASCAR Hall of Fame induction. Ka-chow.
