The musical is based on the 1995 novel Wicked: The Life and Times of the Wicked Witch of the West by Gregory Maguire, and tells the story of Elphaba's life prior to becoming known as the Wicked Witch of the West from L. Frank Baum's The Wonderful Wizard of Oz (which was later adapted into the classic 1939 film starring Judy Garland).

The original Broadway production won three Tony Awards and six Drama Desk Awards, as well as a Grammy Award.

The musical film was initially set for release on Dec. 22, 2021, but it was pushed back due to the coronavirus pandemic. In February, Chu confirmed he was set to helm the picture.
