While Wicked puts a revisionist spin on the earliest Oz tale, the story's connection to its original source material remains integral.

Jon M. Chu’s musical starring Ariana Grande and Cynthia Erivo is defying gravity at the box office — but it was a winding yellow-brick road of Hollywood adaptations to get here from 'The Wizard of Oz' (1939).

As a theater kid and movie fanatic, I simply cannot stop singing the Wicked soundtrack, checking out all the new Mattel dolls, and re-watching the Wicked trailer. And I absolutely wore Glinda's signature pink when the Wicked movie flew into theaters2.
