We already used the slowmo to fit in Luke’s “We’ll always be with you.” It worked there because it was just a close-up shot of Rey. Not sure if it can work as flawlessly here. I agree with Sherlock.
What do you mean? If it’s right before Rey calls the saber to her at the climax of the film, that wasn’t retimed.
“We’ll always be with you, but this is your fight”
