Angela Lansbury Will Return to Her Disney Roots in the Upcoming Mary Poppins Sequel

The Hollywood Reporter has confirmed that Streep is in serious talks to play Topsy, Mary's cousin, which would make Mary Poppins Returns the third movie she's costarred in with Blunt. Not much else is known about her role, but it's safe to assume that Streep is the perfect choice (she's the perfect choice for any role, to be honest).
