The casting announcements for Wicked keep coming, and the highly-anticipated musical movie is shaping up to be pretty epic. Last year, it was officially announced that the long-awaited film was finally coming from In the Heights director Jon M. Chu with Ariana Grande playing Glinda and Cynthia Erivo playing Elphaba. It's also been reported that Bridgerton star Jonathan Bailey is playing Fiyero, Jurassic Park alum Jeff Goldblum is in final talks to play the Wizard, and Broadway veteran Ethan Slater is taking on the role of Boq. After the news of Slater's casting was announced yesterday, many Broadway fans were eager to find out who would be playing Madame Morrible, the headmistress of Crage Hall at Shiz University. Today, the casting has been revealed, and it's definitely a pleasant surprise.
