Mary Kate “MK” Morrissey plays Elphaba in Wicked on Broadway. On social media, she gives fans a look into her “ordinary days” as a musical theater superstar.

If you’re not familiar with the story of Wicked, allow me to fill you in: It takes place in the Land of Oz, where witches Elphaba and Glinda form a profound friendship while attending Shiz University.

Idina Menzel and others open up about the pleasures and perils of playing Elphaba, the iconic “Wicked” character.
