Wicked (musical) [SEP] Introduction
Wicked is a Broadway musical by Stephen Schwartz and book by Winnie Holzman. It is based on the 1995 Gregory Maguire novel "", itself a retelling of the classic 1900 novel, "The Wonderful Wizard of Oz" by L. Frank Baum and the 1939 Metro-Goldwyn-Mayer film "The Wizard of Oz". The musical is told from the perspective of the witches of the Land of Oz; its plot begins before and continues after Dorothy Gale arrives in Oz from Kansas, and includes several references to the 1939 film and Baum's novel. "Wicked" tells the story of two unlikely friends, Elphaba (the Wicked Witch of the West) and Galinda (whose name later changes to Glinda the Good Witch), who struggle through opposing personalities and viewpoints, rivalry over the same love-interest, reactions to the Wizard's corrupt government, and, ultimately, Elphaba's private fall from grace.
