This collection of videos seems to be from the Game of Thrones DVD special features. It has a lot of neat background information that are sprinkled in the novels. For any avid fan of the HBO series but haven’t had time to read the books, let these videos burn up an hour of two of your reeducation. I’m serious, if you watch these videos and then go back and watch the series, I guarantee you that you’ll see and hear a lot of references you didn’t catch before.
