Doc Hudson is a character in the 2006 Pixar film Cars. He is an anthropomorphic 1951 Hudson Hornet and is voiced by Paul Newman in his last non-documentary film role and in his only animated film role. In the film, Doc is the medical doctor and local judge for Radiator Springs. After meeting Lightning McQueen, Doc reveals that he is actually a former Piston Cup racer known as the Fabulous Hudson Hornet, and returns to the Piston Cup to act as Lightnings crew chief in his races. Docs racing number is 51, a reference to his model year. In real life, a 1951 Hudson Hornet owned by Dave Bonbright, one of the automotive historians who worked on the Cars films, is Doc Hudson in real life.
