In the four decades that Star Wars has dominated pop culture, we’ve never had to hear a soundtrack for a live-action movie that wasn’t written by John Williams. Williams wrote the original trilogy, and then the follow-up prequels, and even dove back in for the soundtrack for Star Wars: The Force Awakens. So the fact that Williams did not write the music for Rogue One: A Star Wars Story is just one of many ways in which Rogue One represents a departure from the main story. No Star Wars crawl, no John Williams, no problem? I guess we’ll see.
