I can't believe I haven't written anything about this story here! It's a perfect example of how to make the movieverse tolerable for a book lover...
It's also such a good manifestation of you as a writer, if I may say so. You attention to detail is amazing, and what you can do with what you notice is even more so. Also, it doesn't feel as if you're changing the movie; you're adding to it in a very inobtrusive and natural manner, and I almost believe this was part of the original script...
