It was loosely adapted into a 1939 motion picture, ''The Wizard of Oz,'' which has over the course of years become one of the most beloved movies of all time. It was released when Technicolor was still a relatively new process—the three-strip process having been introduced in 1932. It plays on the novelty of color by presenting the first reel, when Dorothy is awake and in the real world of Kansas, in black-and-white, then switching to color for the scenes set in Oz. | It was loosely adapted into a 1939 motion picture, ''The Wizard of Oz,'' which has over the course of years become one of the most beloved movies of all time.
