Star Wars: The Rise of Skywalker is the final movie in the saga that kicked off the with the original Star Wars movie in 1977, and it's set to hit theaters in December. It follows 2017's The Last Jedi, which left fans with a variety of unanswered questions. Now co-writer Chris Terrio has spoken about two of the questions that he says will new movie will address.

In a new interview with Empire, Terrio explained that Rey, played by Daisy Ridley, will be at the center of the first. There had been much speculation about the identity of her parents in the build-up to The Last Jedi, and that film's reveal that they were not special or notable disappointed many fans. While he doesn't give away anything specific, Terrio does hint that there might be more to her backstory than we have learnt so far.

"One of them is a simple [question]: 'Who is Rey?'," he says. "Which is a question that people not only wonder about quite literally, but wonder about in the spiritual sense. How can Rey become the spiritual heir to the Jedi? We kept coming back to 'Who is Rey?', and how can we give the most satisfying answer to that not only factually--because obviously people are interested in whether there's more to be learned of Rey's story--but more importantly who is she as a character? How will she find the courage and will and inner strength and power to carry on what she's inherited?"

According to Terrio, the other issue that The Rise of Skywalker will deal with is the Force itself. "The second one is, 'How strong is the Force?'," he revealed. "It sounds a little simple, but actually when you get down to it, that is a sort of Zen Koan that we would really meditate on--not literally in yoga poses or anything, but like we would discuss, 'What is the Force and how strong is the Force?' Those two things were really important."

Star Wars: The Rise of Skywalker is directed by JJ Abrams, who previously helmed 2015's The Force Awakens. It also stars Adam Driver as Kylo Ren, John Boyega as Finn, Oscar Isaac as Poe Dameron, Kelly Marie Tran as Rose Tico, Lupita Nyong'o as Maz Kanata, Domhnall Gleeson as General Hux, Mark Hamill as Luke, and Billy Dee Williams as Lando.
