One particular aspect of the Wicked stage musical must be changed in the upcoming 2024 film adaptation, and it has to do with The Wizard of Oz. Wicked is a Broadway musical loosely adapted from Gregory Maguire's book, Wicked: The Life and Times of the Wicked Witch of the West. The book, in turn, is based on L. Frank Baum's children's novel The Wonderful Wizard of Oz and the subsequent 1939 film adaptation, The Wizard of Oz. Beginning years prior to Dorothy Gale's unexpected arrival in the Land of Oz, Wicked tells the story of the Wicked Witch of the West (originally called Elphaba Thropp) and Glinda the Good (originally called Galinda Upland)'s unlikely friendship.
