18 References to the Original Mary Poppins in Mary Poppins Returns You Might Have Missed

Blink and you might miss the sweet cameo from the original Jane Banks. As Jane and Jack talk outside their home, a woman (actress Karen Dotrice) approaches them and asks where 19 Cherry Tree Lane is. When they tell her it's two doors down, she politely replies, "Many thanks, sincerely," giving a nod to the song "The Perfect Nanny" from the first film, where Jane and Michael sign off their letter for a new nanny with, "Many thanks, sincerely, Jane and Michael Banks."
