plus it’s a small change that makes it match the other 2 movies
Not really trying to escalate this, but it is more of a change than that. It was intended as a small inobtrusive change, certainly, but it failed due to careless editing. Watch the arrival of Tatooine with the 77 crawl – the planet comes into view right on the musical cue (considering the projected frame was slightly smaller than the 35mm frame, it was likely perfectly timed for theatres), as the original editing intended. Now try the 81 crawl. The entire planet misses its cue, and by no small margin. Cracks me up every time I see it, like the stormtrooper head-bonk.
