When we first meet Travers (Emma Thompson), she has fallen on hard times yet refuses the advances of Disney (Tom Hanks).
Yet the filmmaker is persistent, telling Travers that, ‘20 years ago I made a promise to my daughters that I would make your Mary Poppins fly off the pages of your books’.
Eventually, Travers flies to America to meet Disney and his team including Don DaGradi (Bradley Whitford), Richard Sherman (Jason Schwartzman) and his brother Robert (BJ Novak).
Despite a touching friendship with chauffeur Ralph (Paul Giamatti), Travers is unmoved by the re-imagining of her cherished text. Something has to give and it is Disney who realises tif he is to win over the author, he must confront the ghosts of his own past.
