The two Cars movies that Pixar has made so far are my least favorite of any Pixar film, but the kids love them regardless, and they also make money. I'll be surprised if we ever wee a third Cars film, but Pixar has released three short films for the franchise that some of you Disney/Pixar fans might like to check out.
The short series is called Tales From Radiator Springs and they were directed by Jeremy Lasky. The first is called Hiccups, and features Lightning McQueen getting the Hiccups. The second is called Bugged, and features fire engine Red getting Bugged, and the third one of called Spinning, and is about Guido with a Spinning sign.
