If Emily Blunt and Lin-Manuel Miranda weren’t enough to get you excited about Mary Poppins Returns, maybe Meryl Streep’s name on the roster will do the trick.

Mary Poppins Returns is not a remake of the original 1964 classic but rather a sequel to the Julie Andrews-led musical. As such, it stands to reason that we’ll be getting some new characters this time around. One of those characters will be Miranda’s Jack, who will be a street lamplighter.

And, according to Variety, another one of those new characters will also be portrayed by none other than Meryl Streep, who will be taking on the role of Mary Poppins’ cousin, Topsy. And, yes, the legendary actress will be taking on a singing role for the film.

This will also reunite Streep with her Into the Woods co-star Blunt, as well as Director Rob Marshall and Producer Marc Platt. Streep played the Witch in Into the Woods, while Blunt portrayed the Baker’s Wife opposite James Corden.

Disney’s official synopsis for Mary Poppins Returns reads:

Blunt has been cast as Mary Poppins and 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 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.

Mary Poppins Returns and will hit theaters December 25, 2018.
