Nearly every performance of Wicked has sold out since its opening more than two years ago. The Chicago company and the national company of the musical are also solid hits, and the London production, which will open in the fall, sold £100,000 worth of tickets during the first hour tickets were on sale.

The New York company is currently headed by Eden Espinosa as the green-faced Elphaba and Megan Hilty as the curly locked Glinda. Ben Vereen co-stars as the Wizard with Carol Kane (Madame Morrible), Derrick Williams (Fiyero), Jenna Leigh Green (Nessarose), Sean McCourt (Dr. Dillamond) and Robb Sapp (Boq).

Based on Gregory Maguire's novel, which turned every Oz myth inside out, Wicked explores the early life of the witches of Oz: Glinda and Elphaba. The two main characters meet at Shiz, a school where both hope to take up sorcery. Glinda is madly popular and Elphaba is, well, green. By a misunderstanding, they wind up roommates and, after an initial period of mutual loathing, begin to learn something about each other. Their life paths continue to intersect through a shared love, entry into the Emerald City and interaction with the Wizard himself. Eventually, their choices and convictions take them on widely different paths.
