Annabel Banks is the rambunctious young daughter of Michael Banks who heartily embraces living with her Aunt Jane and brothers, John and Georgie. She would love nothing more than to help her family avoid losing their home, but her financial abilities are not quite up to standards. When Mary Poppins arrives, however, her enthusiasm and pure heart seem to meet their match.
Annabel was the second child born to Michael and Kate Banks after her older brother, John. She became the only girl in her family after the birth of her younger brother, Georgie. She had a happy life with her family as they lived in Jane and Michael's childhood home. However, after Kate's death, they started to fall apart and even more when their home received a foreclosure notice.
Role in the film
Annabel is introduced during the musical number "(Underneath the) Lovely London Sky" alongside John at the beginning of the film. She, John, and Georgie go downstairs while the lawyers, Hamilton Gooding and Templeton Frye, prepare to have a conversation with Michael just as they leave for the park.
At the park, Annabel, John, and Georgie encounter Miss Lark and her pet dog, Willoughby, to which they chase the runaway kite, much to the Park Keeper's warning about staying off the grass. Georgie grabs the kite during a strong wind just as Annabel and John plan to save him; the wind, however, stops when Mary Poppins arrives toward them, telling them to be more careful when flying the kite just as she takes them home. As she does so, Michael and Jane are happy to see her back. Just as they talk to her in their bedroom, they arrive at the bathroom where she sings the musical number "Can You Imagine That?" just as she transforms the ordinary bathtub into a magical one. Mary Annabel, John, and Georgie dive into it and end up in an underwater world sequence. As they swim along, they encounter a pod of dolphins who put John, Annabel, and Georgie into bubbles to reach the surface and Mary pops them so they can stay with her. Just as the pod of dolphins leap across the bathtub, she opens the drain plug, causing her, John, Annabel, and Georgie to end up back home.
Back at home, John, Annabel, and Georgie talk to Michael about their adventure under the sea much to him not having time to talk, telling him that he is looking for his document which is due by Friday at midnight. Mary tells Annabel and John to put the books back on the shelf and Georgie to take out the rubbish to which he grabs a drawing of his family while carrying it out. At the nursery, Mary tells John to help out the maid, Ellen, in the kitchen, Annabel to do the laundry, and Georgie to fix the broken kite Michael used to play with. While Mary talks to Jack outside where he tells her that he has seen the Banks family ever since, John, Annabel, and Georgie fight over the Royal Doulton bowl, causing it to crack. Mary then spins it, causing her, Jack, John, Annabel, and Georgie to end up in the animated sequence where all the inhabitants are anthropomorphic animals. At Shamus' carriage, they fix it just as he takes them across the animated sequence.
During the musical number "The Royal Doulton Music Hall", Mary, Jack, John, Annabel, and Georgie stroll across the animated sequence just as John, Annabel, and Georgie watch Jack and Mary perform on stage with all the anthropomorphic animals, including the Penguin Waiters, during the musical number "A Cover is Not the Book". After the performance, John, Annabel, and Georgie notice that their plush giraffe, Gillie, is stolen by the Wolf. They board Shamus' carriage just as he and Clyde agree to help them; they manage to save Gillie from the Wolf and his henchmen, the Badger and the Weasel, as they fall off the edge of the bowl. Back at home, Mary says that they must be having a nightmare during the chase sequence where she sings to them that nothing is lost forever, comforting them and telling them to sleep.
Mary, Jack, John, Annabel, and Georgie leave home while Admiral Boom and Mr. Binnacle fire their cannon to mark the signal just as they arrive at Topotrepolovsky's All Repairs Large and Small Fix-it Shop to fix the broken bowl where they encounter Topsy who refuses to let them in. Barging in, they encounter her again and she refuses to fix the bowl at first because of Second Wednesday. She then introduces them in her shop about everything going topsy-turvy in there. She, however, agrees to accept Mary's request to fix the bowl just as they leave.
Walking across London, Mary, Jack, John, Annabel, and Georgie encounters Jane again and Jack encourages her to ride on his bike just as Mary, John, Annabel, and Georgie arrive at the bank to see William Weatherall Wilkins who would help with the Banks' home while John, Annabel, and Georgie explore the bank. They encounter Penny Farthing who talks to him as they wait outside. It is later found out that he is identical to the Wolf from the animated sequence who is also an obstacle in both the real world and the animated sequence just as they tell Michael about this; he, however, refuses to believe in them just as he tells Mary to take them home, despite that they are telling the truth. On their way home, they discuss about Wilkins' true nature. Back at home, Michael is very upset with them telling him that he could have lost his job to which John explains that they are trying to help to which Michael denies, warning him that their home is about to be repossessed.
During the musical number "Trip a Little Light Fantastic", Jack shows Mary, John, Annabel, and Georgie across the street encountering a group of lamplighters; Jack and the lamplighters dance together on Cherry Tree Lane just as Mary, John, Annabel, and Georgie return home.
Seeing the Certificate of Shares printed backwards on the kite patched up by John, Annabel, and Georgie, Michael realizes that this is linked to the bank, having only about seven minutes till midnight to which he plans to return to the bank while Mary agrees to help John, Annabel, and Georgie turn back time with help from Jack. As they watch Jack and Mary working together, she manages to help him stop Big Ben before it strikes midnight to which afterward, she tells him to relight it much to Wilkins' chagrin. Just as he refuses to accept the certificate all patched up together, Michael tells him that John, Annabel, and Georgie are telling the truth just as his uncle, Mr. Dawes Jr., confronts him for his lies and deception to the Banks family, telling Gooding and Frye to take him away.
With Wilkins gone, the Banks family retain their home back just as Mary happily watches them and everyone else happily using balloons during the musical number "Nowhere to Go But Up" just as the Balloon Lady gives the Banks family each a balloon. Mary, however, lets hers go just as she bids farewell to the Banks family. As everyone has fun using balloons, the Banks family returns home as Mary leaves via her umbrella to mark the end of the film.
