The AFI Silver here in the DC area will be showing ESB in August. I remember hearing last year about how the ESB screenings here and there were actually still the old 2k dcp, so I suspect this will be the same. Kinda puzzling why they wouldn’t be showing the newer 4k version, but then again LFL/Disney might not want to prepare new dcp’s until it’s time for an actual grand re-release in 3D and Dolby Cinema and Imax.
Of course, AFI Silver could theoretically be showing an actual ‘97 print (the info listed says 1980/1997, so it can’t be any older than that), but I doubt Disney even wants pre-2011 versions out there anymore.
