Hey, just wanted to share a few resources that might be helpful when tracking changes in the Star Wars Special Editions — both audio and video.

There are some great threads on TSWT.com:

Original Trilogy Dolby Atmos Theatrical Synced Soundtracks

SRDXX 1997 AC-3 THX Laserdisc Audio Synced to the Original Star Wars Trilogy

“I Never Noticed This Before” – Audio Edition

The White Executor Bridge in Return of the Jedi (Blu-ray, 4K, Disney+)

Have I Discovered a Special Edition Change?

There’s also this spreadsheet, which includes tons of Special Edition differences — and even pre-Special Edition audio and video changes.
It can be a bit overwhelming at first, but it’s definitely a valuable resource:

Shot List Spreadsheet – v0.6

And if you’re digging deeper into the audio side specifically, this could be super helpful:

Index of OT.com Threads on All Things Audio

Hope this helps!

Only thing to note about that shotlist is that it incorrectly claims that a lot of ESB SE audio changes were in the 70mm mix. There wasn’t a proper copy of that mix when the list was created so incorrect assumptions were made, the 70mm Print A over on the TSWT forums is the best source to use for tracking audio differences in the 70mm mix.
