I mean, weren’t the reused shots of Leia taken from interactions with characters that weren’t Rey? And even if they were using scenes with Rey why would her clothes and hair be a problem? They changed Leia’s look with CG so I don’t see how Rey a new look would have been an issue. I think we’re just rationalising the decision to rehash her TFA look. Worst case scenario, JJ doesn’t have an atom’s wight of creativity. Lol.
Supposedly, the big issue was the hug shot. They couldn’t get it to look right with new/different hair, which makes sense, given that her hand’s literally in Rey’s hair, lol.
