This looks quite fun. I probably won't watch it live, but will hope to be able to see it later. Some general observations here...
Sean Astin looks like he's aged quite a lot, considering I also watched The Goonies for about the 50th time recently.
Dom Monaghan looks like he hasn't aged a day from when he first played Merry.
Ian McKellan reading one of his lines from the movies makes me want to go watch all 3 of them now.
