According to an article on USAToday.com Harry Potter author J.K. Rowling says that Alfonso Cuaron, who directed The Prisoner of Azkaban, which opens next Friday, inadvertently foreshadowed events that will happen in books six and seven, which she has yet to complete.
Rowling goes on to tell USA Today, “I really got goose bumps when I saw a couple of those things, and I thought, people are going to look back on the film and think that those were put in deliberately as clues,” Rowling says in an interview released by Warner Bros., which is distributing the movie.
Cuaron, for his part, says “in a way, it was intuition, but everything is so emotionally eloquent, the book gives you all the hints.”
