With a score by Stephen Schwartz and a book by Winnie Holzman, "Wicked" has been one of Broadway's biggest success stories since it arrived in 2003 starring Kristin Chenoweth as Glinda and Idina Menzel as Elphaba.
The Wicked Witch, Elphaba (originally played by the excellent Idina Menzel), turns out to be good, while Glinda the Good Witch (originally played by Kristen Chenoweth) is exposed as a smug, ambitious, manipulative bitch, with little talent for sorcery.
