Watch: Behind the scenes on the set of ‘Wicked’

Fans have been given a sneak peak behind the scenes of the making of the 'Wicked' film.

A newly released featurette gives us a glimpse of the ‘Wicked’ set, and provides insight into what the roles of Elphaba and Glinda mean to stars Cynthia Erivo and Ariana Grande.

The clips come ahead of the release of the official trailer on Wednesday.

Wicked, a prequel to The Wizard of Oz, tells the story of Elphaba (Erivo), a young woman, misunderstood because of her unusual green skin, who has yet to discover her true power, and Glinda (Grande), a popular young woman, gilded by privilege and ambition, who has yet to discover her true heart.

The two meet as students at Shiz University in the fantastical Land of Oz and forge an unlikely but profound friendship. Following an encounter with The Wonderful Wizard of Oz, their friendship reaches a crossroads and their lives take very different paths.

Glinda’s unflinching desire for popularity sees her seduced by power, while Elphaba’s determination to remain true to herself, and to those around her, will have unexpected and shocking consequences on her future.

Their extraordinary adventures in Oz will ultimately see them fulfill their destinies as Glinda the Good and the Wicked Witch of the West.
