Yes I agree it is an assembly and it would have had for instance different options included within it.
My point about montross is that this was turned into a continuation of the Jabba scene first and unwritten if we are to trust the actor that originally played greedo.
Then a new version was filmed during principle photography that allowed for another option and a much better way to do the scene.
It is an assembly of options all on the table at once. You will have multiple takes of scenes also perhaps strung together it would not be like watching a film but multiple versions of scenes with options. At 13 reels it will have a lot of alternate angles and various dialogue changes and tonality deliverance of lines from actors.
It’s not that there is a massive amount more just that there are options to what is there with a bit of deleted scenes naturally most things are alternatives than a deleted scene in film.
My dear Ronster, what came before the shooting script is of little importance because it WOULD NOT HAVE BEEN FILMED. There would be nothing to include in a rough cut of the film. That is what the lost cut is, a rough cut of the film. The first cut of the film I believe. It led to changing editors, lots of lines being trimmed, and lots of frames being trimmed in other places. So if you have valid information on something that was shot or if your research into trying to figure out if the shots in some scenes were reordered based on the sound mix, then you would contribute, but continuing to go back to much earlier drafts that had been discarded and bringing up theories that don’t fit the facts as we have them is just getting you in trouble. Download a copy of the shooting script. Read it. Memorize it. That is the guide to what was filmed. That was included in the lost cut. We know a heck of a lot about the filming schedule and can piece together if there was even room for anything extra, but there wasn’t money for it. So chances are that there was nothing filmed that wasn’t in the shooting script.
