Disney dropped the official trailer for “Mary Poppins Returns” on Monday, and Emily Blunt is ready to serve up a spoonful of sugar.

Blunt plays the eponymous role that Julie Andrews made famous in the 1964 classic musical fantasy. Set in London 25 years after the events of the original film, the highly anticipated sequel sees Poppins back to help the next generation of the Banks family after they experience a personal loss.

The long-awaited sequel has rounded up a pretty impressive lineup. Stepping into the massive shoes of the magical nanny herself is Emily Blunt. Meryl Streep portrays Poppins’ cousin Topsy, who wasn’t in the first movie. The cast also includes Colin Firth, Angelia Lansbury, Dick Van Dyke, Emily Mortimer, and Julie Walters. The sequel features all new original songs with music by award-winning composer Marc Shaiman and lyrics by Scott Wittman and Shaiman.

“Mary Poppins Returns” hits theaters on December 21st. Watch the trailer above.
