So many changes…
For one, Jyn was definitely radically retooled. She’s been turned from the militant heroine who wants to “smash stormtroopers heads in” to the Casablanca-esque party, who wants nothing more to remain neutral and “ignore the Imperial flags above her.” This required entirely reshooting Saw, who originally discouraged Jyn (“What will you become?”) instead of persuading her to do the exact opposite- “Keep the dream alive.” If you ask me, her arc in the movie as-is is much more poignant.
Actually have heard from Screen Junkies and other sources that the Jyn vs TIE shot in the trailer was just created for promotional material, as others have said. In any case, that’s how LFL wants to spin it, regardless if it’s true or not.
The bulk of the changes in the climax appear to be paring it down, so they don’t need to run across the beach (largely shown in promos) to a separate building to upload the plans. Paring down was probably a direct result of reshoots expanding the space battle climax, so not to make the movie too long; as-is, Scarif battle lasts more than half an hour. Krennic/Jyn confrontation looks wobbly FX-wise, as if it was reshoots; that was probably freshly done, with dialogue altered or Krennic originally not being on top of the shield at all.
Also, agree that the Vader scene pictured above and seen in Trailer 1 was just the pre-reshoot permutation of what was ultimately shot on Mustafar, likely with a different Vader actor, judging by the fact that 2 are ultimately credited. Hopefully, it is included on the BD.

Lastly, anyone know where this shot would have come in?


No idea why Jyn is piloting alongside Cassian unless K2 is dead. Complete speculation, but could it be from an alternate happy ending that LFL claims was never shot?
Again, speculation but if Jyn was originally the very militant, angry troubled young woman; it’s possible that her scripted arc was for her to stop fighting, lest she become something horrible as Saw suggested, and consequently leave it to the heroes to save the galaxy. When Disney decided to go with a darker ending, her arc naturally had to be changed.
Anyone else agree?
