During production of the thriller movie “A Quiet Place,” Emily Blunt said her marriage with co-star and director John Krasinski became stronger, contrary to warnings from others. In this week’s Sunday Sitdown, the British-born actress talks to Willie Geist about working with her husband as well as what it’s like to have the stamp of approval from “The Devil Wears Prada” co-star Meryl Streep and the original Mary Poppins, Julie Andrews.
