Walt Disney's first animated feature film was Snow White and the Seven Dwarfs, released in December 1937. It cost $1.5 million, three times over budget, and by May 1939 its gross of $6.5 million made it the most successful sound film made to that date.
Walt Disney died of lung cancer on the 15th of December 1966, at the age of 65. A heavy smoker since World War I, he had been diagnosed in early November 1966 and died of circulatory collapse caused by the cancer before Disney World and the EPCOT project were completed.
Accusations that Walt Disney was racist or antisemitic have been contradicted by many who knew him. Biographer Neal Gabler, who gained unrestricted access to the Disney archives, concluded the evidence does not support the antisemitism charge, while describing Disney as racially insensitive like most white Americans of his generation but not a racist.
