In the book and the movie “The Wizard of Oz” there are two wicked witches – from the East and West, respectively. And in both versions, when Dorothy lands in Oz, she’s greeted by a good witch, but the two stories don’t agree on who she is. According to the book, it’s the unnamed Good Witch of the North, but in the movie, it’s Glinda (Billie Burke), also referred to as the Good Witch of the North. Yet in the book, Glinda is actually the Good Witch of the South, and Dorothy doesn’t meet her until she goes to find her in the final chapters.
By combining the two characters, the film eliminates the need to introduce another character late in the story and ensures that Glinda is a reliable force for good throughout. However, it also creates a bit of intrigue: Glinda gives Dorothy the magical ruby slippers at the start of her time in Oz, but does not reveal that they have the power to bring the girl home until she went through many trials and tribulations. , leaving open the question of why Glinda held Dorothy for so long. It’s like Obi-Wan handing Luke that lightsaber on Tatooine, but never showing him how to light it.
In the book, the Good Witch of the North has no idea what the shoes can do, so it’s more understandable that Dorothy doesn’t end her long quest in Oz until she meets Glinda at the end of the book.
