Wicked only covers the first half of the beloved Broadway production, and the film drops several hints about things that are going to happen in the second part. The Wizard of Oz prequel has been one of 2024’s most culturally significant films, with plenty of people rushing to the cinema for the first time in a while to see John M. Chu’s cinematic vision of this musical classic. The story centers around Elphaba and Glinda, two witches who meet at Shiz University and, by the end of Wicked, ultimately become the Wicked Witch and the Good Witch from The Wizard of Oz.
