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."
