Star Warsfans were shocked when it was announced thatCarrie Fisherwill be returning forStar Wars 9without the use of CGI or another actress, and now Mark Hamill is commenting on his on-screen sister’s return. Lucasfilm and J.J. Abrams revealed that Fisher will be back as Leia Organa in the final movie of the new trilogy thanks to unused footage from 2015’sThe Force Awakens. Lucasfilm and Disney vowed that they would not use CGI or bring in another actress to replace Fisher in one of most iconic roles of all time. This left many fans to wonder how they would address her absence inStar Wars 9.

Mark Hamillposted on social media to declare how happy he is that Carrie Fisher will be back forStar Wars 9with him. Obviously, it’s bittersweet for Hamill, and the whole crew of the movie, but this seems like the best outcome for the film. Hamill is really happy that Fisher won’t be replaced and calls the late actress “irreplaceable.” He had this to say.

“It’s bittersweet facing my final chapter without her-She is simply irreplaceable. I’m finding solace in the fact that she won’t BE replaced & would love the worldwide outpouring of affection from those who loved her when they heard the news.”

Star Wars 9was originally going to center on Carrie Fisher’s Leia Organa, much likeThe Force Awakensput the focus on Harrison Ford’s Han Solo andThe Last Jediput the spotlight on Mark Hamill’s Luke Skywalker. However, that all changed in December of 2016 when Fisher sadly passed away. While many believed that her performance inThe Last Jediwas going to be the last, J.J. Abrams and Lucasfilm discovered that they had enough unused footage to bring her back.

It’s unclear how the unused footage fromThe Force Awakenswill be utilized and how much of it will make it intoStar Wars 9. With that being said, it sounds like a tricky task that will involve some serious digital heavy lifting in the post-production process. It’s also unclear if the film will give Leia Organa a proper goodbye, or if they’ll let the character live on through the last installment in the new trilogy.

Star Wars 9officially begins shooting in England next week and details are still pretty scarce as they will more than likely remain throughout the filming and post-production process. That just means that there’s still a lot more to look forward to in the coming months, like the official title. At least the cast was announced, revealing that Mark Hamill, Carrie Fisher, and Billy Dee Williams will all be returning forStar Wars 9.
