I once dreamed that I came across a special restored cut of A New Hope that included never before deleted scenes that completely changed the movie.
-Lando shows up. Turns out he’s an old friend of Luke this whole time. They went to the Jundland wastes to rescue R2 and there’s a big shoot out with the Tusken Raiders.
-The shootout attracts the attention of the Imperial fleet, who arrive with black Gunndam-like mechs to disrupt what they imagine to be rebel terrorism.
-Darth Vader shows up too. Not only because he feels the stolen plans are there and wants to find the droid personally, but because ”These mechs have 26 different transformation stages, and I want to be the first one to see them all!”
-By the time he steps into one of them, a passing Imperial rover drives over one the arms/wings, rendering it useless.
-In his anger he force-throws a bunch of Stormtrooper pilots out of their cockpits.
-Finally the rebels actually show up hoping to fight, but Darth Vader is actually doing the most damage, so they just sit and watch. Luke and Lando are already gone by this point.
-Later on, there were test shots of Carrie Fisher’s stunt double inside the set of a damaged Death Star. Although dressed as Leia and even had the hair, the double looked a lot like Leonardo DiCaprio
These weren’t CGI shots, nor were they filmed twenty years after the fact. All of these were filmed in 1976 and were merely cut for time and narrative pacing. Apparently Harmy used various sources to put all this together as part of his new side-project.
The runtime was about six hours long.
