Here is my attempt at the opening. I added the opening shot of Mustafar from Rogue One, as well as doing my best to color grade it to match The Rise of Skywalker. I even used music from the soundtrack that was part of the opening that didn’t make it in. Some VFX work can be done to remove Krennic’s shuttle.
The color correction works, the music isn’t quite there. I’d recommend using the track “Journey to Exegol,” which is what plays when Kylo battles on Mustafar.
That is the track I used, it’s extended on the soundtrack but wasn’t featured in the movie. Give it a listen, just after the crawl fanfare.
Wrong track, that one is called “Fanfare and Prologue.” It was intended for the deleted scene of Kylo talking to the Oracle, and doesn’t really fit into the final movie. The one Dom was talking about, “Journey to Exegol,” is the one that plays immediately afterwards. It has a neat fusion of Kylo’s theme and the Mustafar theme from ROTS, and it would be really cool to hear during an extended opening scene.
EDIT: I see you corrected your post, so this post is kind of pointless now. I would like to hear the other track during the Mustafar scene, if someone could be able to do that. I haven’t been able to figure out this whole editing thing.
