Golden Globe Award winner Emily Blunt has been cast as the title character in Mary Poppins Returns, a sequel to the 1964 Disney classic. The film will be released on December 25, 2018.

Emmy, Grammy, Tony Award and Pulitzer Prize winner Lin-Manuel Miranda, best known for Hamilton will also star in the film.

Miranda will play a new character, a street lamplighter named Jack. Drawing from the wealth of material in P.L. Travers’ seven additional novels, the story will take place in Depression-era London (when the books were originally written) and follow 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.

Reuniting the director and producing team behind Disney’s musical Into the Woods, the film will be directed by Rob Marshall from a screenplay written by Oscar nominee David Magee based on The Mary Poppins Stories by P.L. Travers.

“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.

Oscar nominee and Tony Award winner Marc Shaiman will compose an all-new score. Shaiman and Emmy nominee and Tony Award winner Scott Wittman will also write new original songs for the film.
