Aug. 7 (UPI) -- Cynthia Erivo says the Wicked sequel, Wicked: For Good, is "wild" and "really, really epic" in a "First Look" video released Wednesday.

The clip includes commentary from film stars Erivo and Ariana Grande, who portray Elphaba and Glinda, respectively, and director Jon M. Chu.

Erivo and Grande discussed the evolving friendship between their characters.

"They realize that what they had in film 1 can never come back again and what they have to move into is something very different," Erivo says. "I believe that their bond is unbreakable, but it is deeply challenged by the distance that they have to navigate.... It's wild, it's unbridled, and it feels really, really epic."

"We really just get to see how far we can push this friendship," Grande says.
