It was recently revealed that Disney was planning a sequel to the 1964 musical "Mary Poppins," directed by Rob Marshall, who won the Academy Award for Best Picture for "Chicago." It is reported that the script for the sequel to "Joy in the World" was written by David Magee, the screenwriter of "Finding Neverland" and "The Fantasy Drift of Pi". The story is set 20 years after the 1964 film, and the protagonist is still Mary Poppins and the Banks family. As a musical film, the music creation of "Happy People 2" is also a top priority. For this reason, Rob Marshall specifically found "Hairspray" music creators Marc Shaiman and Scott Wittman, who will create original songs and a new soundtrack for this sequel.
