After what feels like the longest of waits, we finally have first official trailer Disney's Mary Poppins Returns with dancing penguins and all!

Set in 1930s London, 25 years after the events of the original film Jane and Michael Banks are now grown up, with Michael having children of his own. After a family tragedy strikes, the flying oddball nanny with the bottomless bag pays a visit to number 17 Cherry Tree Lane to help the grown up Banks rediscover the joy they knew as children.

The trailer has captured everything that made the original a classic. From its half-animated, half live-action sequences to a family-friendly story that is bound to give you all the feels, including tap dance number performed by original cast member Dick Van Dyke.

For those worried whether Emily Blunt was going to be able to step into the role made famous by Julie Andrews and do the character justice, this trailer is sure to ease all worry. She looks like she's done a superb job.
