Cynthia Erivo on Elphaba's evolution in "Wicked" sequel and what to expect as she hosts Tony Awards on Sunday

Cynthia Erivo said her character Elphaba has evolved into a more powerful, self-aware version in the upcoming "Wicked" sequel, describing the green-skinned witch as "a little more knowing" ahead of hosting the 78th Annual Tony Awards on Sunday night.

"They are not in school anymore. They are in their power," Erivo said. "I love this part of Elphaba. I call it 'delicious,' and I do feel that strongly. She's just a little more knowing ... The wardrobe is different. The hair is different. Everything is sort of moving toward the maturer version of who she is."

Erivo's return to host the Tony Awards marks what she calls "a beautiful full circle moment" for the actress who won a Tony in 2016 for her portrayal of Celie in "The Color Purple." She credited her Broadway work with launching her career and leading to opportunities including her Oscar-nominated performance as Elphaba in the first "Wicked" film.
