You wouldn’t know from The Devil Wears Prada (2006), A Quiet Place (2018) and Mary Poppins Returns (2018) that Blunt had a childhood stutter. Acting in school plays helped her smooth out her speech. “When you act, you access a different part of your brain, "she explains. "It's removal of yourself that allows a sort of fluency. I felt liberated by that.” She works today with the nonprofit group the Stuttering Foundation to help others.
