Star Wars: The Rise of Skywalker sets up Rey’s new Star Wars movie in several ways, both directly and indirectly. Originally marketed as the end of the Skywalker saga, The Rise of Skywalker is no longer the final chapter in the story that chronologically began with Star Wars: Episode I – The Phantom Menace. Rey’s new Star Wars movie is not Episode X, but it is a continuation of the Star Wars sequels nonetheless.
