While early rumors claimed up to 40% of Rogue One would be reshot, Disney later stated that the changes primarily had to do with “clarity and character development.”
The movie’s reshoots lasted for five weeks this past summer, and were managed by Michael Clayton director Tony Gilroy (who also contributed rewrites).
Taking place shortly before the events of A New Hope, Rogue One will follow Felicity Jones’ Jyn Erso and her Rebel allies as they attempt to secure the plans for the Death Star while avoiding Imperial director Orson Krennic’s (played by Ben Mendelsohn) forces.
Gilroy is also reportedly working on the final cut of the movie with director Gareth Edwards, so the two of them will presumably be listening to Michael Giacchino’s music together and deciding which tunes go in, one of the last post-production tasks that needs to be completed.
