Travers’ seven additional novels, the story will take place in Depression-era London (when the books were originally written) and follows a now-grown Jane and Michael Banks, who, along with Michael’s three children, are visited by the enigmatic Mary Poppins following a personal loss. Through her unique magical skills, and with the aid of her friend Jack, she helps the family rediscover the joy and wonder missing in their lives.”

“I am truly humbled and honored to be asked by Disney to bring P.L. Travers’ further adventures to the screen. The iconic original film means so much to me personally, and I look forward to creating an original movie musical that can bring Mary Poppins, and her message that childlike wonder can be found in even the most challenging of times, to a whole new generation,” says Marshall.

The original P.L. Travers works were introduced back in 1934, the first book in the series was simply called “Mary Poppins,” which Disney adapted and released in August, 1964. That film was directed by Robert Stevenson and starred Julie Andrews and Dick Van Dyke.
