In Pixar's Cars, former Piston Cup champion Doc Hudson secretly lives in Radiator Springs as a doctor.
Doc is the town's local physician and judge when Lightning McQueen arrives. He initially hides his racing past and resents the attention brought by Lightning's arrival. The film reveals that Doc was the Fabulous Hudson Hornet, a celebrated racer who won three Piston Cups before a crash ended his competitive career.
Doc's history explains his harsh attitude toward Lightning. He recognizes the rookie's talent but fears that the same obsession with speed and publicity will lead to disappointment. Paul Newman voiced Doc Hudson, making the character one of Newman's final major film roles. Doc is often confused with The King, another veteran champion who still competes in the first film; The King is Strip Weathers, while Doc is the retired Hudson Hornet.
