Lady and the Tramp was the first animated film distributed by Buena Vista Film Distribution, Disney’s new film distribution company. The 15th Disney animated feature film was the first animated feature filmed in the CinemaScope Widescreen film process. In 1937, Walt Disney Productions story artist Joe Grant came up with an idea inspired by the antics of his English Springer Spaniel Lady, and how she got “shoved aside” by Joe’s new baby. He approached Walt Disney with sketches of Lady. Disney enjoyed the sketches and commissioned Grant to start story development on a new animated feature titled Lady. Through the late 1930s and early 1940s, Joe Grant and other artists worked on the story, taking a variety of approaches, but Disney was not pleased with any of them, primarily because he thought Lady was too sweet, and there was not enough action.
Walt Disney read the short story written by Ward Greene titled “Happy Dan, the Cynical Dog”, in the Cosmopolitan magazine, published in 1945. He thought that Grant’s story would be improved if Lady fell in love with a cynical dog character like the one in Greene’s story, and bought the rights to it. The cynical dog had various names during development, including Homer, Rags, and Bozo, before “Tramp” was chosen.
