Three months before "Rogue One: A Star Wars Story" arrives in theater, the franchise spinoff has found a new composer.

Originally, Alexandre Desplat, known for his work on "The Twilight Saga: New Moon," "Harry Potter and the Deathly Hallows" and "Godzilla," was scheduled to compose the music. However, that was before "Rogue One" underwent extensive reshoots, which pushed the postproduction schedule to the point that Desplat was no longer available.

Now, according to The Hollywood Reporter, Disney has turned to a composer the studio has worked with before: Michael Giacchino.

Giacchino has a long-standing relationship with Disney, having scored Pixar's "The Incredibles," "Cars 2," "Inside Out, "Ratatouille" and "Up." He also wrote music for Disney's "Sky High," "John Carter," "Zooptopia" and "Tomorrowland." The composer for the rebooted "Star Trek" franchise, Giacchino is also with Marvel Studios on "Doctor Strange." With "Rogue One," he'll have worked for all four of Disney's film arms.

A "Star Wars" fan, Giacchino told The Hollywood Reporter last year that listening to John Williams' original score inspired him to pursue a music career.

"I was 10 years old in 1977 when I ran down the steps on Christmas morning to find the double album LP of 'Star Wars' waiting for me," he recalled. "I ripped it open, ran back up to my bedroom and threw it on the turntable. That was the day I truly understood that music was storytelling. I listened to that album day and night, memorizing every single note. By studying those liner notes, I discovered the various instruments of the orchestra, learning which type of instrument was used for this or that cue. My education in music had begun. So at 10 years old, I began listening to John Williams. I listened to everything I could get my hands on. It started with his scores to 'Close Encounters,' '1941,' 'Raiders of the Lost Ark,' and so on. The second a new John Williams score hit the shelves, I was begging my parents to buy it for me — which they always did. I would repeat the same process as I did with 'Star Wars': the repeated listenings, the studying of the orchestrations and, even more importantly, the storytelling."

Giacchino even played a stormtrooper in "Star Wars: The Force Awakens."

Williams scored the previous seven "Star Wars" films. "Rogue One" will be the first in the series without music from Williams.

Directed by Gareth Edwards, "Star Wars: Rogue One" stars Felicity Jones, Diego Luna, Ben Mendelsohn, Donnie Yen, Riz Ahmed, Mads Mikkelsen, Alan Tudyk, Jiang Wen and Forest Whitaker. The film opens Dec. 16.
