Emily Blunt appears in teaser for 'Mary Poppins Returns'

July 16 (UPI) -- Disney released a snippet of footage of Emily Blunt as Mary Poppins in the upcoming sequel, Mary Poppins Returns, at the D23 Expo in Anaheim.

Blunt and director Rob Marshall also dropped by to chat about the film, which is to open in December 2018. Saturday's 21-second sneak peek shows Blunt in a long blue coat, and red hat and gloves, lifting her umbrella as the rain clears and sun comes out.

The sequel to the 1964 movie musical Mary Poppins will see the "practically perfect" nanny returning to visit her former charges the Banks children after a family tragedy. Its ensemble will also include Lin-Manuel Miranda, Meryl Streep, Angela Lansbury, Emily Mortimer, Colin Firth, Ben Whishaw, Julie Walters and Dick Van Dyke.
