The Secret Life of Mary Poppins

In 1964 the Mary Poppins film premiered in Hollywood to world acclaim. But one person loathed it. She was PL Travers, the author of the books. This Culture Show special presented by Victoria Coren Mitchell explores the dark and complex life of the writer; her 20-year battle with Walt Disney, the strange adoption of her child (he was one of twins), and how the film version overshadowed her writings but made her rich. With contributions from Emma Thompson, Cameron Mackintosh and PL Travers's granddaughter.
