The Wizard of Oz (1902 musical)
The Wizard of Oz was a 1902 musical extravaganza based on "The Wonderful Wizard of Oz" by L. Frank Baum, which was originally published in 1900. Much of the original music was by Paul Tietjens and has been mostly forgotten, although it was still well-remembered and in discussion at MGM in 1939 when the classic film version of the story was made. Although Baum is the credited bookwriter, Glen MacDonough was hired on as jokewriter after Baum had finished the script.
The Wonderful Wizard of Oz (1910 film)
The Wonderful Wizard of Oz is a 1910 American silent fantasy film and the earliest surviving film version of L. Frank Baum's 1900 novel "The Wonderful Wizard of Oz", made by the Selig Polyscope Company without Baum's direct input. It was created to fulfill a contractual obligation associated with Baum's personal bankruptcy caused by "The Fairylogue and Radio-Plays", from which it was once thought to have been derived. It was partly based on the 1902 stage musical "The Wizard of Oz", though much of the film deals with the Wicked Witch of the West, who does not appear in the musical.
