10 Most Insane Cameos In Recent Movies

10. Idina Menzel & Kristen Chenowith - Wicked

It wasn't exactly a huge surprise that Idina Menzel and Kristin Chenoweth showed up in Wicked - having originated the roles of Elphaba and Glinda on the Broadway stage. 

In fact, it was really just a case of fans waiting to see where they'd show up.

And ultimately, Menzel and Chenoweth appeared as the leading members of the Emerald City Players, just as Elphaba (Cynthia Erivo) and Glinda (Ariana Grande) make it to Emerald City in search of the Wizard of Oz (Jeff Goldblum).

Elphaba and Glinda are welcomed to Emerald City with the song "One Short Day" from the Emerald City Players' production of "Wiz-O-Mania", and as the leaders of the troupe, Menzel and Chenoweth take center stage to belt out the tune.

On one hand it's shameless fan service, but on the other, it's basically the perfectly meta way for the duo to make a cameo that nods to their own legacies. 

Director Jon M. Chu originally planned to include the pair in far more subtle, non-musical roles, but ultimately felt they needed a scene to showcase their singing chops, and wasn't that the right choice or what?
