Wicked, with a book by Winnie Holzman and music/lyrics by Stephen Schwartz, is a wildly successful Broadway musical that tells the untold story of the witches of Oz, focusing on the unlikely friendship between Elphaba (the Wicked Witch of the West) and Glinda (the Good Witch) before Dorothy's arrival. Based on Gregory Maguire's novel, it explores themes of perception and prejudice, becoming a global phenomenon with tours, a long Broadway run, and recent two-part film adaptations for which Holzman also co-wrote the screenplay.
