Paul Newman provided the voice of the retired racing legend Doc Hudson in Pixar's Cars.
Doc is revealed to have been the Fabulous Hudson Hornet, a celebrated race car whose career ended after a serious crash and a long period of being overlooked. He initially hides his racing history from Lightning McQueen.
Newman was an acclaimed actor and also a successful professional race-car driver. His real-life connection to motorsport gave special resonance to his performance as an older champion who understands both the glory and danger of racing.
Cars was Newman's final feature-film voice role. Doc's character is inspired by the real Hudson Hornet automobile, a car associated with early stock-car racing and NASCAR history.
