David Magee (Finding Neverland) has written the script, which draws on material from author P.L. Travers' other Poppins novels that followed the original. Set nearly 25 years after the 1964 film, the story this time finds the magical nanny returning to the Banks family in Depression-era London to find that her charges Jane (Mortimer) and Michael (Ben Whishaw) Banks have now grown up. Michael has three children of his own, and they all need a little help re-discovering the joy in life.
Mary Poppins (Emily Blunt) will need the help of street lamplighter Jack ( Lin-Manuel Miranda) and cousin Topsy (Meryl Streep).
With Rob Marshall (Into The Woods) making the magic happen in the director's chair and Scott Wittman and Marc Shaiman (Into The Woods) providing the necessary tunes, Mary Poppins Returns will kick off shooting next year and is eyeing a 25 December 2018 release in the US. There is as yet no word whether it will arrive over here at the same time.
