Walt Disney Pictures is teaming up with filmmaker Rob Marshall to develop a sequel to the studio's beloved 1964 classic Mary Poppins. Variety confirms that the story will be set 20 years after the film, using plot lines from author P.L. Travers' eight literary sequels, including the first follow-up Mary Poppins Comes Back. No specifics were given for the story, except that this sequel will follow the title character's furthering adventures with the Banks family.

The original Mary Poppins starred Julie Andrews as the title character, alongside Dick Van Dyke, David Tomlinson, Glynis Johns, Hermione Baddeley and Reta Shaw. Author P.L. Travers wrote eight Mary Poppins books, but it isn't known if this theatrical follow-up will be adapted from a specific story within those books, or if it will be an amalgam of those stories. P.L. Travers' literary sequels include Mary Poppins Comes Back (1935), Mary Poppins Opens the Door (1943), Mary Poppins in the Park (1952), Mary Poppins From A to Z (1962), Mary Poppins in the Kitchen (1975), Mary Poppins in Cherry Tree Lane (1982) and Mary Poppins and the House Next Door (1988).

Director Rob Marshall is directing from a screenplay by David Magee (Life of Pi and Finding Neverland). Rob Marshall is teaming up with musicians Marc Shaiman and Scott Wittman (Hairspray), who will compose original songs and a new score. The filmmakers are also working with P.L. Travers' estate and the project has the blessing of Mary Poppins composer Richard M. Sherman, who wrote the movie's famous songs like "Chim Chim Cher-ee" and "Supercalifragilisticexpialidocious" with his late brother, Robert B. Sherman.

Rob Marshall is also producing alongside John DeLuca and Marc Platt, who all collaborated on last year's Disney musical adaptation Into the Woods. This project comes just two years after the release of Disney's Saving Mr. Banks. That film told the behind-the-scenes story of how Walt Disney convinced P.L. Travers to turn Mary Poppins into a feature film, which earned $116.5 million at the box office worldwide during its theatrical run.
