Set decades after the original classic film, Mary Poppins Returns stars Emily Blunt as the titular nanny, who returns to London to assist the now-grown Jane and Michael Banks. Because of the unique nature of this sequel, comparing the Mary Poppins Returns cast to the original Mary Poppins characters presents a fascinating view of this magical film. Both Jane and Michael, played by Emily Mortimer and Ben Whishaw, are now grown, making it fun to compare them to the original childhood versions of these characters. Dick Van Dyke, originally Bert and Mr. Dawes Sr. from the first film, now plays Mr. Dawes Jr. in a clever nod to the original, while Julie Walters plays Ellen the housemaid.
Instead of bringing back figures like Bert or George Banks, Disney cast new counterparts to parallel original Mary Poppins characters. Lin-Manuel Miranda plays Jack, an apprentice to Bert, while newcomers Pixie Davies, Nathanael Saleh, and Joel Dawson parallel the younger Jane and Michael Banks from the first film. These 21st-century updates and changes add new chapters to the overall Mary Poppins story and behind-the-scenes tales from Disney's films about the magical, musical nanny.
