doubleofive has written three quality and in-depth articles on the topic for The Digital Bits website, titled:-
‘A Visual Guide to Changes, Fixes & Tweaks in the 2019 SE Version’ - for each of the three Original Trilogy films…
doubleofive’s exhaustive and comprehensive work cataloging the changes made to the Original Trilogy films (including the 2019 SE Disney+ version) can also be found at the following…
• Star Wars Visual Comparisons twitter page
• Star Wars Visual Comparisons website
• Star Wars Visual Comparisons blog
The pinned Complete Comparison of Special Edition Visual Changes thread in the Theatrical Cuts vs. Subsequent Releases section of the site is pretty much the default discussion thread on the overall subject.
Within the first post of the linked thread above is a list of many other sources of information which also cover the numerous and continuing alterations made to the Original Trilogy films over the years - and the differing released versions - including content on the changes made for the 2019 SE Disney+ version.
It also features doubleofive’s ‘Disney+ Should Offer the Star Wars Original Cuts’ article on the Wired website : #ReleaseTheOriginalTrilogy : also with an OT.com thread on the article here.
The Complete Comparison of Special Edition Visual Changes thread also features OT•com member 13las’s insightful and informative YouTube videos on the changes made to the OT over time:-
• Star Wars
• Empire Strikes Back
• Return Of The Jedi
• The Prequels
• and also for the 2019 SE Disney+ version too.
‘Shot List Spreadsheet - v0.6.05 - 6 films - Multiple SW Audio Mix Changes Added’ - OT•com thread, by none, is also well worth a thorough read.
Yet, yes - of course… if anyone spots any further changes not already found or noticed for the 2019 SE Disney+ version, please mention them in here…
