Los Angeles: Academy Award-winning actress Meryl Streep is in talks to join Emily Blunt and Lin Manuel-Miranda in Disney's sequel to "Mary Poppins". If a deal closes, the family film titled "Mary Poppins Returns" would reunite Streep with the Into the Woods musical team of Blunt, director Rob Marshall and producers Marc Platt and John DeLuca, variety.com reports. Marshall and DeLuca are also producing the film. David Magee wrote the screenplay, based on the stories by P.L. Travers, with Marc Shaiman composing an all-new score and writing original songs with Emmy nominee and Tony-winner Scott Wittman. Streep and Blunt also shared screen space in the film The Devil Wears Prada. Streep is said to play the role of Poppins' cousin, Topsy, a supporting role that wasn't in the 1964 classic. She would also sing for the part, much like she did in Into the Woods, which earned her a record 19th Oscar nomination. "Mary Poppins Returns" is set to release in the US on December 25, 2018.
