DoubleOO5: The wipes were also redone. This is maybe not "altering" the film, but like the re-comps it does constitute changing the original negative. For instance, in the wipe from the sandcrawler to the stormtroopers, there was a change in colour grading once the wipe began, because it was prepared before the final grading was done, so it never totally matched and you could see the colour jump if you looked closely. This has been corrected so that now the wipes have the same grading as the material around it.
