As they have grown rather fond of doing, Disney is looking back at one of their past hits in order to create some future success. After modern day versions of Cinderella, Sleeping Beauty and Alice in Wonderland (not to mention, upcoming versions of Beauty and the Beast and The Jungle Book), Disney has hired Rob Marshall (Chicago, Into the Woods) to direct a new Mary Poppins musical based on P.L. Travers’ original children’s books.
