Watch Cynthia Erivo Sing "For Good" Ahead of Her "Wicked" Role

Cynthia Erivo is offering a glimpse at her Elphaba. Fresh off an appearance at Sunday's SAG Awards, the actor and singer appeared on "The Late Late Show With James Corden" on Monday and participated in a game where she and Corden had to guess which staffers have secret singing abilities. It was during the game that Erivo performed a snippet of "For Good" from the musical "Wicked," which is currently being turned into a film starring Erivo opposite Ariana Grande. Though less than a minute long, the performance further proved the impeccable casting.

Despite its successful run in theaters worldwide for nearly two decades, "Wicked" is just now being adapted with "Crazy Rich Asians" director Jon M. Chu at the helm. The origin story follows the unexpected friendship between Glinda the Good Witch and Elphaba, who later becomes known as the Wicked Witch of the West.

Though production won't begin until this summer, Erivo said she's already begun bonding with Grande, who will play Glinda. "Ariana and I have been meeting and chatting and talking and building our own relationship because we know that it's a sisterhood," she told E! at the SAG Awards. "We want to be ready and prepared to be there for one another."
