Most people say that it’s ridiculous to say that the Harry Potter books saved lives, but read this and you’ll change your perspective. Evanna Lynch, who plays Luna Lovegood in Harry Potter, once wrote to J.K. Rowling begging for at least a tiny role in one of the films. At the time she was young and was dying due to her anorexia. She mentioned it to J.K. and begged to have one part in the film before it was too late. J.K. Rowling responded with a deal: she’d give her a part if she got better. Evanna got better and never returned to her anorexia.
