A couple of weeks ago we hosted a movie night. We showed The Princess Bride, a perenial favorite. Amazingly, there were several people who had never seen it before (we own a copy of the 20th Anniversary Special Edition, so it's not like people haven't had time to see it)! There were also a bunch who had seen it many times, and could say a lot of the lines along with the movie. I can say some of the really famous key lines. My nephew Al and his wife Debra host Princess Bride showings when the turn the sound track off completely, and the party guests are required to supply ALL the lines.
It was a lot of fun, and even the newbies enjoyed this wonderful classic film.
