Seeing as to how that shot of Leia breaks my immersion every time I see it relocated in a fan-edit, my vote would be that it’s worth the effort. However, after watching the clip again, I would suggest that the only person who actually needs to be removed is the one guy that strolls past, everyone else should be fine to leave as is.
I’ll see what I can do 😉 I agree with most here that there’s not much issue with the background extras, just that one casually strolling through.
Watching this reminded me of a personal annoyance that just gets me every time, and since I first saw it I now can’t unsee it. In the room where Kylo kills Han, the balcony/entrance that Rey and Finn stand at has a railing, and on that railing are lights. The lights have a red light on the left and right of the fixture. But really annoyingly, the lights just look clipped on to the railing, and one is offset. I don’t know why, but that’s always taken me out of the scene, even though it’s not even really that egregious, possibly not even an error.
I have noticed those lights, but never considered that it’s an issue that one is off-center. I figure that there would probably be a lot of that on a base as large and hastily constructed as Starkiller.
