“They came to me once, for the third one,” he remembered of “The Prisoner of Azkaban”. “I’ve read them all, and when I read the books before the movies were done, I always pictured Charles Dickens – they were very Dickens-ian. The situation of Harry Potter reminded me a lot of Pip from ‘Great Expectations’. I saw them as deeper, more creaky, more corroded; then [the stories] were textured very differently when the first two movies came out. They were so bright and happy and full of light, that I wasn’t interested.”
