Who wrote the screenplay?
A number of writers had a hand in developing the screenplay. Noel Langley, Florence Ryerson, and Edgar Allan Woolf received the official credits, Langley was credited with the adaptation, and most of what appeared on screen is their work. But Herman J. Mankiewicz (who would win an Oscar in 1942 for writing Citizen Kane), Ogden Nash, William Cannon, Irving Brecher, Herbert Fields, Samuel Hoffenstein, Jack Mintz, and Sid Silvers all worked on The Movie at one point or another. John Lee Mahin did some uncredited clean-up writing and quick scene rewrites during production, and lyricist E. Y. Harburg provided some of the segues into the songs and other bits of dialogue, including most of the Wizard’s speech to Dorothy’s friends as he gave them what they wanted.
