When it comes to bringing a new musical to Broadway, producers find inspiration in all sorts of places - including beloved movies. Tina Fey premiered her musical version of the hit movie Mean Girls in April 2018. "The greatest thing about bringing this musical to life is that our creative team didn't say, 'Can you just recreate the iconic film performance?' We could never hope to," Erika Henningsen, who played Lindsay Lohan's character Cady Heron on stage, exclusively told Us Weekly in April 2018.
