Well I am not a Star Wars Super Expert but you need to look at a few documentaries also.

You need to look at the original Making of Star Wars (1977) there are a few shots in that.

You will find a better alternate take of Han Running up the Ramp on to the Falcon from a different angle. You also get shot’s of Landspeeders driving through Mos Eisley. Tie Fighters being blown apart on blue screen. Deleted Y-wing fly over.

Deleted Magic I can’t seem to find a good quality version of it now days has cool stuff in it too. It has the Landspeeder display when R2-D2 is located, so I don’t know where that came from either originally as it’s a compilation from various sources.

The Best Deleted Footage for Empire is in some of the trailers although the best one for cut footage is not in cinemascope. You won’t be able to use the take of Vader force lifting and choking Luke off the Gantry Crane and throwing him down the shaft either. As it was obviously changed 😃

There is an extended snippet of R2-D2 lifting himself up to the window of Yoda’s hut from the 2004 DVD menu of Empire

Empire Strikes Back SFX documentary has some alternate audio.

don’t use the shot of Vader communicating with Luke in Return of the Jedi lightsaber construction scene. Vader in his meditation chamber was from Empire Strikes Back.

That about covers All that I can think of at the momment.
