There are plenty of reasons to see John M. Chu’s film adaptation of "Wicked," chief among them being this stellar cast’s renditions of some iconic tracks. Since the film first started screening, people haven’t been able to stop gushing about Ariana Grande and Cynthia Erivo’s live vocal performances. This is guaranteed to produce some memorable and emotional moments, especially if you were on set at the time of filming and a choir of birds decided to join in.

Haven spoken with John M. Chu himself, and when describing his biggest “goosebumps moment” during production on "Wicked," he told a beautiful story of when Cynthis Erivo as Elphaba sang one of the musical’s most emotional songs, "I’m Not That Girl", with help from some feathered friends.
