Another legendary actress has joined Disney’s Mary Poppins sequel Mary Poppins Returns.

Angela Lansbury has been cast as Balloon Lady, “a treasured character from PL Travers’ series of Mary Poppins children’s books,” according to Disney. The actress voiced Mrs. Potts in their animated Beauty and the Beast and starred in Bedknobs and Broomsticks.

Filming just kicked off last weekend in England at Shepperton Studios. The movie is set to open in theaters December 25, 2018.

Mary Poppins Returns stars Emily Blunt, Lin-Manuel Miranda, Ben Whishaw, Emily Mortimer, Julie Walters, Colin Firth, and Meryl Streep. Joining them are three new Banks Children played by Pixie Davies, Nathanael Saleh, and newcomer Joel Dawson. Dick Van Dyke will also appear.

The Mary Poppins Returns synopsis from Disney reads:

The film is set in 1930s depression-era London (the time period of the original novels) and is drawn from the wealth of material in PL Travers’ additional seven books. In the story, Michael (Whishaw) and Jane (Mortimer) are now grown up, with Michael, his three children and their housekeeper, Ellen (Walters), living on Cherry Tree Lane. After Michael suffers a personal loss, the enigmatic nanny Mary Poppins (Blunt) re-enters the lives of the Banks family, and, along with the optimistic street lamplighter Jack (Miranda), uses her unique magical skills to help the family rediscover the joy and wonder missing in their lives. Mary Poppins also introduces the children to a new assortment of colorful and whimsical characters, including her eccentric cousin, Topsy (Streep).
