Now, youll recall that a little bit ago, I said these should probably be best considered new 2011 versions of these films, and not the 2004 DVD versions. All the fixes and corrections alone justify this in my opinion, but theres another reason too and you can probably guess what it is: Once again, George has apparently added a few new surprises into these films. I dont know what they are and didnt get to see any of them on Friday, but I was assured that there will be new things to notice when we watch the films.
