How does JK Rowling feel about the Marauders Map being left out of Prisoner of Azkaban?
She writes: “I was fine with it. It is simply impossible to incorporate every one of my storylines into a film that has to be kept under four hours long. Obviously films have restrictions novels do not have, constraints of time and budget; I can create dazzling effects relying on nothing but the interaction of my own and my readers’ imaginations – hence my preference for the page over the screen.
