It was a dual tragedy: Carrie Fisher died at age 60 of a heart attack on Dec. 27, 2016, and her mother, Debbie Reynolds, passed away from a stroke at 84 the next day. “I do miss them both tremendously,” Todd Fisher, Debbie’s son and Carrie’s brother, recently told ABC News. “At the same time, I have so much left behind by them both, and so many great memories.”

Fans will be able to enjoy some of those mementos soon. “We have a lot of her artifacts and a lot of things of hers that she’s written that will someday be shared,” Todd said of his sister, who built on her career as an actress in Star Wars by becoming the bestselling novelist of Postcards From the Edge. “There’s a lot more to come from Carrie.”

That includes a final appearance as Princess Leia in the ninth Star Wars movie, set for release in December 2019. “There’s a lot of minutes of footage. This is unused, new content that could be woven into the storyline. That’s what’s going to give everybody such a great kick. It’s going to look like it was meant to be. Like it was shot yesterday,” Todd explained.

On the recent two-year anniversary of Carrie’s untimely death, the star’s daughter, Billie Lourd, paid tribute to her mom by posting a sweet video to Instagram. “I decided to do something we both loved to do together — sing,” Billie, 26, captioned the clip of herself performing “These Days” by Nico. “As the song says, we must ‘keep on moving.’ I hope this encourages everyone who’s feeling a little low or lost to ‘keep on moving.’”

As for Todd, “Every day, I remember ‘my girls’ and try to help keep their memories alive,” he previously wrote via Twitter. “There is not a day that goes by that I do not think of them. They frequently visit me in my dreams. They send their love, as they always did in life.”
