- Constructive Criticism: The play had a test run in San Francisco a few months before the Broadway debut. The producer said that while he felt the New York critics had made up their mind about the play already, the San Francisco critics instead gave advice that helped the play grow to its current form (such as giving Elphaba a stronger role).
- Recursive Adaptation: If the rumored film adaptation of the Wicked musical develops, it will be a movie based on a musical based on a novel based on a movienote based on a playnote based on a novel. At minimum.
- Word of Gay: Kristin Chenoweth and Idina Menzel have said that they believe if things had gone differently, Galinda and Elphaba would've eventually fallen in love. The same was said by some other cast members and Maguire.
