The 25-year-old actor will reprise her character, Rey, in "The Last Jedi", which also stars Mark Hamill, John Boyega, Oscar Isaac, Adam Driver, Gwendoline Christie and Domhnall Gleeson.
"For me, I didn't really know what I was signing on to. I hadn't read the script, but from what I could tell, it was really nice people involved, so I was just like, 'Awesome.' Now I think I am even luckier than I knew then, to be part of something that feels so like coming home now," Ridley told Rolling Stone.
However, Ridley has not completely ruled out revisiting the role in the distant future.
"Who knows? I honestly feel like the world may end in the next 30 years, so, if in 30 years, we are not living underground in a series of interconnected cells, then sure. Maybe," Ridley said.
