In select theaters December 13 and everywhere December 20, Saving Mr. Banks chronicles the real-life struggle and untold backstory of how the Disney classic Mary Poppins made it to the big screen. Disney's daughters begged him to make a movie out of the beloved Travers book, but when the curmudgeonly and uncompromising Travers refused to yield to Disney's magical vision, his promise to his daughters turned into a 20-year quest to obtain the rights and find a way to please Travers.
