The Devil Wears Prada is already a critically acclaimed book and movie, but now it seems the story may be headed to Broadway. According to the Associated Press, the hit 2006 film starring Meryl Streep, Anne Hathaway and Emily Blunt is currently being developed into a song-and-dance with producer Kevin McCollum. The David Frankel film, which followed a fish-out-of-water journalist working at a fashion magazine with an intolerable boss and also starred Stanley Tucci and Adrien Grenier, grossed $324 million worldwide.
