With regards to the version, I assume they want to project using 35mm, and the only version Lucasfilm hands out on film is the 97. They never bothered to make a DCP of them (since they’re not the newest version), not did they bother to make film prints of the 2011, because very few studios still release this widely on film.

I wish I could attend one of the showings, but the nearest one is more than 600 miles away from me. Not really worth it, I’m afraid. I’ll just have to wait for another day to finally see them theatrically. I wasn’t born yet in 77 and too young to see them in 97, and I didn’t want a 7 film marathon just to see the 2011 versions. Oh well.
