This new trailer for Mary Poppins Returns is sure to give you ALL the feels. It's a sequel that takes place 54 years after the original. The Banks family’s children, Jane and Michael (Emily Mortimer and Ben Whishaw), are all grown up and have kids of their own. When tragedy strikes, Mary Poppins (Emily Blunt) returns to help the family get their priorities back on track. The cast looks amazing as alongside Blunt we have Lin - Manuel Miranda, Meryl Streep, Angela Lansbury, Colin Firth, original star Dick Van Dyke, (now 92), even has a small role in the film, but sadly, his co-star Julie Andrews declined to appear in the new movie. Mary Poppins Returns will be released on December 19
