I could try a concept clip of how the opening could go. I’ve been thinking about it, and I’m not sure if using those two shots of Ben in the bridge from the deleted scene from The Last Jedi would work and would probably feel even more abrupt to cut from him on the ship to him in action on ground.

I think we can keep looking for more footage of ash filled forests and lava, but I think using the opening shot of Mustafar from Rogue One with some color correction and VFX work to remove Krennic’s ship can work.

I’ve also noticed from listening to the soundtrack that some pieces of John Williams’ music were not in the movie and the soundtrack features extended score. Listen to the opening track.
