Cars

"Cars" was Pixar's seventh feature film, released in 2006, and earning $462 million. It was the last film Pixar produced before it was bought by Disney.

"Cars," which was based on the live-action film, "Doc Hollywood," featured a cast of, well, cars. The main character, Lightning McQueen, is a brash rookie race car who ends up stuck in a small Southwestern town.

The film achieved a notable technological innovation, implementing computerized procedural animation to display 300,000 individual car "fans," a process neither Pixar nor any other studio had done before.

"Cars 2" is now in pre-production and should hit theaters in 2011.
