Here's Your First Look at Emily Blunt and Lin-Manuel Miranda on the Set of 'Mary Poppins'

After the news that Dick Van Dyke will be returning for the Mary Poppins sequel for "a little song and dance number," the new cast have been spotted kicking their knees up and linking their elbows in homage to the iconic "Step In Time."

Emily Blunt, who will be taking on the role of the practically perfect nanny, was spotted filming the highly anticipated Mary Poppins Returns alongside a load of chimney sweeps on April 2 in London's St James' Park.

The 34-year-old actress was joined by Hamilton creator Lin-Manuel Miranda, who plays a lamplighter rumored to be modeled on Van Dyke's character Burt from the 1964 original.

Shooting scenes outside Buckingham Palace, various chimney sweeps can be seen riding bicycles through London's smog.

Mary Poppins Returns picks up with the Banks children more than 20 years after the events of the original Disney classic in 1930s London, with Jane and Michael all grown up with families of their own.

Written by Life of Pi's David Magee, the film sees Mary Poppins returning to help the Banks family rediscover joy after Michael suffers a personal loss.

Blunt will be joined by a star-studded cast in Rob Marshall's reboot, including Ben Whishaw and Emily Mortimer, who play the older versions of Jane and Michael Banks.

Colin Firth has also signed on as William Weatherall Wilkins, the boss of the Fidelity Fiduciary Bank, with Julie Walters playing loyal housekeeper Ellen and Meryl Streep as Mary Poppins' cousin Topsy.

Mary Poppins Returns will hit cinemas December 2018.
