The changes behind the scenes of Rogue One: A Star Wars Story continue. After this summer’s reshoots, which also saw Tony Gilroy come aboard the production to assist (or, according to some reports, oversee) shooting the additional material and the film’s final editing, The Hollywood Reporter says the film is now getting a new composer as well.

Director Gareth Edwards initially planned to collaborate with Alexandre Desplat on the score for Rogue One. But now Desplat is out and Michael Giacchino is in. THR says those dastardly reshoots are to blame for upsetting everyone’s schedules.

The reshoots also altered the scoring calendar and Desplat, who won an Oscar for The Grand Budapest Hotel, was no longer available. Disney and Lucasfilm then turned to Giacchino, who has a long relationship with the studio and its various divisions.

Giacchino is a busy man. He’s already composed two film scores this year; Disney’s Zootopia and Star Trek Beyond. (He’s worked on all three Kelvin timeline Treks and composed the bombastic themes for this new version of the franchise.) He’s also got Doctor Strange coming out in November as well. He’s going to have some mighty big shoes to fill, too. Forget about Desplat, who’s a pretty great composer in his own right. By replacing him on Rogue One, Giacchino will become the first composer on a Star Wars movie whose name is not John Williams. No pressure, Michael! All you have to do is live up to the greatest composer in movie history, on the franchise where he created his most iconic work! Should be a snap.

Rogue One: A Star Wars Story opens on December 16.
