Typescript draft for the 1939 motion picture The Wizard of Oz. This draft of the script by primary screenwriter Noel Langley is dated between May 4 and 6, 1938, and it contains original corrections and additions in pencil and ink pen. The challenge of adapting L. Frank Baum's book The Wizard of Oz to film began with the screenplay. From March 1938 to March 1939, more than a dozen people, most uncredited, worked on writing and revising the script. On one page of this script, Langley notes the change from black and white to color. In this famous scene, Dorothy steps out of her farmhouse into Oz and says to her dog Toto, "I've got a feeling we're not in Kansas anymore."
