Wicked has taken the world by storm since its November 22nd release. The fans have pronounced their love for the film, with some liking the movie more than the Broadway show even though there are some notable alterations.

Ariana Grande and Cynthia Erivo weren’t just in sync on the Wicked set— but prior to filming as well. The actresses revealed in an interview with Variety published on Thursday, Jan. 2, that after being hired as the two leads of the film, they worked together to ensure that both of their needs were met on the set.

Ariana Grande, who is Golden Globe-nominated for her role in Wicked, explained that some of the voice alterations she made for the film are likely to stay.
