Lin-Manuel Miranda has officially begun filming Mary Poppins Returns!

The 37-year-old actor joined Emily Blunt and their kid co-stars as they filmed outside of Buckingham Palace on Saturday night (April 1) in London, England.

Emily and Lin-Manuel were spotted riding around on bicycles as they filmed a scene with flying bicycles around them.

Early last month, Emily Mortimer & Ben Whishaw made their appearances on set as the adult versions of Jane and Michael Banks.

Mary Poppins Returns is set to hit theaters on December 25, 2018!
