😄 First I cobbled together a replacement background using frames from the movie and some painting. I then inserted that background over the original shot and made it follow the camera movement, and added new film noise over it to match the rest of the shot. I then cut out the unnecessary bits of the replacement background so it only covers Kylo Ren and a little bit of background and leaves Hux intact. This is how I did the timecode removal for the deleted scenes as well, even though that was more complex.
You’re a wizard, Ridley. 😎
