Rian Johnson, the director of The Last Jedi, didn't change "a thing" in 'Star Wars: The Last Jedi' in the wake of Carrie Fisher's death. Fisher reprised her role as General Leia Organa, alongside fellow veterans Harrison Ford and Mark Hamill, in the seventh installment of the franchise 'The Force Awakens' and had shot all her scenes for 'Episode VIII - The Last Jedi' before she tragically died in December 2016 at the age of 60.
