Mater and the Ghostlight is a 2006 Pixar computer-animated short created for the DVD of Cars, which was released on October 25, 2006 in Australia and in the United States on November 7, 2006. The short, set in the Cars world, tells a story of Mater being haunted by a mysterious blue light.
The short film opens with Mater playing pranks on the other residents of Radiator Springs. This sequence culminates with Mater teasing Lightning as if he had seen "the Ghostlight," an actual myth on Route 66.
Sheriff admonishes him for mocking the urban legend, and then tells the tale of the Ghostlight. The rest of the gang say goodnight and turn off all the store lights, leaving a very nervous Mater alone.
During the body of the short, mayhem ensues as Mater is pursued by the Ghostlight...ultimately revealed to be just a lantern affixed to Mater's towing cable by McQueen and Guido. The other residents of Radiator Springs watch as Mater drives around frantically with the "Ghost Light" on his tail,...
