On October 3, he asked me what day it was, and told me about the latest developments in the staging of the Mean Girls musical. Earlier this year Tina Fey teased that she was “working on the musical adaptation” of the teen movie in the summer months while Unbreakable Kimmy Schmidt was on hiatus, and now we have some definitive information about its progress — the musical will be debuting at an undisclosed date and theater in Washington, D.C., this fall. Along with Fey, her composer husband, Jeff Richmond, and lyricist Nell Benjamin have been collaborating on the stage adaption. Further information, including the cast, will be revealed at a later date. Grool!
