Composer Stephen Schwartz also cameos as the Oz soldier who allows Elphaba and Glinda into the Wizard’s palace, while the musical’s book writer Winnie Holzman similarly appears in the Emerald City, touting the Wizard’s ability to read the Grimmerie.

The original Wicked Witch of the West and Good Witch of the North have made their way back to Oz. After months of speculation, the theatrical release of Wicked: Part One has confirmed surprise cameos from Broadway legends Kristin Chenoweth and Idina Menzel.

The original "Wicked" witches choose their favorite songs in the musical. Unlimited. Together, they're unlimited. That's always been the case for Idina Menzel and Kristin Chenoweth, who originated the roles of Elphaba and Galinda in the Broadway production of Wicked.
