That's cool, but I think I'll stick to watching them at home. I like the machete viewing order a lot, and being able to use the Harmy "Despecialized Edition" fan cut of New Hope is wonderful. (Need to check if he ever completed any of the other movies with that treatment).
Personally if I'm going to watch through with the in universe timeline order, I like to mix in some of the side shows and movies, which makes it far too long for an extended continuous viewing anyway.
I did the LotR marathon in theaters long ago. Was great fun, but I dunno if I have the patience for that sort of thing now. Might make a point to watch the series at home over the weekend, though. Hope it's a fun time for those who do go, though!
There are so many lighting inconsistency problems with that Skywalker Saga poster, I thought I was going crazy, especially on the left side. In fact, the whole left side is kind of a mess.
