ha. I don't understand how you could be in something so big and be such important characters like Snape or Voldemort or Dumbledore and not have read the books. I mean, that's part of the reason they have so many fans is due to the book, yes? Also Dumbledore was supposed to be a sweet professor the first few until things got serious, so some of his phrasing like his "did what?" in POA or his violent outrage at Harry supposedly putting his name in the goblet seemed off to me. I thought he had more of a hidden strength, shown in the sixth. It was one thing for Felton to put off reading the books, that was ages ago, but without it, he wouldn't have been able to portray Draco so well in the sixth. i suppose the script is all they need. Oh well, they do a fantasatic job nonetheless.
