I just watched the Empire reels and something stuck out at me. I had another look and I believe I have found something quite significant. Check out these screen caps:
2006 GOUT:
Same image from the 1985 CAV Laser:
And the same image from the Super 8 reel:
Another frame from the GOUT as the Emperor fades in:
Same frame from the '85 Laser:
And the Super 8 reel:
The above shot on the Super 8 reel corresponds with reports regarding the 70mm cut of TESB. In the 70mm version, the Emperor's hologram doesn't fade in, just like the Super 8 reel.
Another example:
GOUT DVD:
Same frame from the '85 Laser:
And the same frame from the Super 8:
Again, this corresponds to the 70mm cut.
I believe this is the first confirmed visual evidence of alternate footage existing within one of the films!
Also, this section of Michael Matessino's 70mm list that appeared in Film Score Monthly also appears in the Super 8 reel:
In the final scene, there is no tracked music from "Yoda and the Force". The scene begins with the first establishing shot of the rebel fleet, then cuts inside the Falcon for Lando to say, "Luke, we're ready for take-off" (but a different take of this was used). After Luke says (voice over), "Good luck, Lando" the scene cuts to inside the rebel cruiser where Luke says, "I'll meet you at the rendezvous, " etc. Not in this version are two more establishing shots of the fleet and an interim effects shot over which Lando says, "When we find Jabba the Hutt and that bounty hunter we'll contact you."
Add all of this to the numerous (and already known) differences in the Super 8 audio and this becomes even more intriguing.
Fascinating!
