Okay, another newsflash: I'm a huge fan of Harry Potter, both on the page and on film. (I know. Shocker.) This is one of the best behind-the-scenes videos I've seen (and I've seen many), in which Potter actor Daniel Radcliffe talks to Potter author J.K. Rowling about the books, the films, and the wild ride they both embarked on. Spoiler Alert: They do discuss things you won't want to hear if you've not read all 7 books.
