I don't know how many times I have watched different versions of the Cinderella story. My favourite may still be the original Disney cartoon, where the birds and the mice attempt to help poor Cinderella attend the ball where she meets her prince. She ultimately needs a fairy godmother to turn her rags into a beautiful gown and her pumpkin into a royal coach.
I've probably watched every Christmas movie about a prince meeting the ordinary girl and falling in love. The girl comes up against a wicked stepmother, a resistant queen, a beautiful princess, or an arrogant boss, but her true heart wins...
