Boyega, who plays Finn in the epic space opera franchise, says Fisher will appear onscreen for the final time in perfect manner, according to The Hollywood Reporter.
"This movie, it sends her off in an amazing, amazing way. And she is still kept alive in this franchise. That's the beauty of it: She lives forever in a sense," Boyega says.
The 25-year-old actor says when he learned of Fisher's death last December, "It was a strange, strange feeling. I felt like everyone in the cast went silent for a bit after that."
Fisher passed away in December last year at the age of 60 after she suffered a mid-air heart attack. She was expected to have a role in 2019's Episode IX.
"The Last Jedi" is set to release on December 15.
