Part of me wants them to keep Episode VIII exactly as it would have been and not change a thing, since Carrie had already filmed all her scenes for the movie before her death.

There are a million and one possibilities. I’m sure everyone at Lucasfilm are putting their heads together. As others have said, Carrie would have wanted whatever is best for the sake of these movies. But we also want a worthy tribute to her, a sentiment no doubt shared by the filmmakers.

My thoughts?

I don’t want them reusing footage or using cgi for Episode IX. This is all obviously dependent on how things play out in VIII (and whether or not they simply make changes to that movie as well), but what I would want them to do is to take a page from how Leonard Nimoy’s death was addressed in Star Trek Beyond. Early in Episode IX, have a scene where a group of characters return from a battle. It was a victory, but General Organa was killed leading the Resistance.

An idea someone posted in the comments at birthmoviesdeath that I actually loved:

“(at some point) cut to a memorial statue or plaque, and we dolly out to reveal a person (Finn? Poe? Rey?) paying their respects as they pass by before joining a meeting or on their way to a ship or something.
They could even touch it and say “for luck” before moving on.”

That really got me, but in a good way.

My only other suggestion would be to give Billie Lourd’s character a bigger role in Episode IX. She was just on Late Night with Seth Meyers a couple weeks ago and is becoming quite the actress herself, despite - she mentioned - her family’s best efforts.
