Travers travelled to New York City during World War II while working for the British Ministry of Information. At that time, Walt Disney contacted her about selling to Walt Disney Productions the rights for a film adaptation of "Mary Poppins". After years of contact, which included visits to Travers at her home in London, Walt Disney did obtain the rights and the "Mary Poppins" film premiered in 1964. In 2004, a stage musical adaptation of the books and the film opened in the West End; it premiered on Broadway in 2006. A film based on Disney's efforts to persuade Travers to sell him the "Mary Poppins" film rights was released in 2013, "Saving Mr. Banks", in which Travers is portrayed by Emma Thompson. In a 2018 sequel to the original film, "Mary Poppins Returns", Poppins, played by Emily Blunt, returns to help the Banks family once again.
