Brothers Grimm vs Disney: Cinderella
Cinderella has become increasingly popular with children over time; however the story was not originally intended for small children. The version of Cinderella that everyone has come to love was created by Walt Disney; however there is a darker and more twisted version written by the Brothers Grimm.
In the Brothers Grimm version there is no Fairy Godmother. Cinderella's father is still alive, although he doesn't care much about Cinderella anymore. The Prince's ball takes place over the course of three days and each day Cinderella runs away so on the third day the Prince puts pitch on the stairs, but all it does is cause her shoe to stick. Later in the story, while looking for the girl who fits the shoe, Cinderella's step-sisters take drastic measures to make sure it fits: One step-sister cuts of her toe while the other slices her heel. At the end of the story Cinderella and the Prince still get married, however her step-sisters get their eyes poked out by Cinderella's bird friends.
The differences in the two versions help showcase the "Disneyfication" of stories as well as how the storylines and publishing have changed over time.
