14. Mary Poppins
This 1950s classic, based on PL Traver’s book of the same name, made nannies everywhere popular.
Mary, nanny to two unruly children of a London banker, sets about bringing magic and adventure to their lives – with the help of her friend, Bert (Dick Van Dyke with a famously dreadful London accent).
During her short stay she manages to tame the kids, and bring them closer to their workaholic father.
