Like other supposed production troubles that happened with Rogue One, the film had some concerns in signing on and keeping a composer to tackle the score. Initially, it was French composer Alexandre Desplat, who had signed on for scoring duties back in March 2015 and was eager to begin working on the music. However, schedules did not align with the film's secondary reshoots and he was forced to leave. Enter Michael Giacchino into the fray.
Giacchino is not unfamiliar with either Williams's musical vernacular (Jurassic World comes to mind) and even Star Wars, having scored for the Disneyland Star Tours attraction before. 2016 in particular has been extremely kind to him, with the composer turning out scores for now four major films in this year alone. Fresh off the heels of Doctor Strange, and asked to take over scoring duties soon after Desplat's departure, Giacchino was faced with only four-and-a-half weeks to create over 90 minutes of music for one of the largest space operas of all time, with recording sessions happening over the course of a month or so. Fans were initially skeptical of the score's final quality due to these time constraints and the heavy responsibility Giacchino was meant to carry. With the scores for Zootopia and Star Trek Beyond laughable, and Doctor Strange a remarkably aural and sonic masterpiece, did Giacchino succeed with Rogue One in continuing one of the greatest aspects of the Star Wars franchise?
