There is going to be a D23 weekly online series called "Armchair Archivists". I'm sure I will forget to look at these shows, but I wanted to share their premiere episode, which was released today. In this first episode, they show the last footage that Walt recorded. I actually think he looks and sounds pretty good considering it was filmed less than two months before he passed away.
