Disney’s live-action sequel to its 1964 classic Mary Poppins will hit theaters on December 25, 2018, as Mary Poppins Returns. The company just announced the title and date for its film starring Emily Blunt and Lin-Manuel Miranda. The studio earlier had staked that Christmas date for an “Untitled Disney Live Action #2.”

Blunt will star as the magical English nanny, and Hamilton star Miranda will play a new character, a street lamplighter named Jack. Set in Depression-era London, it 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.

The project reunites Into the Woods director-producer Rob Marshall with that musical’s producing team John DeLuca and Marc Platt. David Magee is penning the screenplay based on The Mary Poppins Stories by P.L. Travers. Marc Shaiman is composing a new score and writing original songs with Scott Wittman.
