​Nearly nothing is known about the final film in the latest Star Wars series, except that J.J. Abrams, who helmed The Force Awakens, will be returning as director, and many of the cast members from both Abrams's earlier effort and The Last Jedi will be reprising their roles. Even the late Carrie Fisher, who sadly passed away on December 27, 2016, will be included in Episode IX, through unused footage from the previous two films.

Though all the stars of the upcoming film are sworn to secrecy about it, Fisher's daughter, Billie Lourd, is spilling what she can. Lourd, who played the minor role of Lieutenant Connix in the last two films, teased what it was like being back on set.

"I gotta watch myself because the Star Wars PD is going to come get me, but it is incredible. I’ve read the script and I’ve been on set," Lourd told ​Entertainment Tonight. "I was on set for, like, three weeks back in September, and it is going to be magical. I can’t say much more, but I’m so excited about it and so grateful to be a part of it. Star Wars is my heart. I love it."

A lot of things are riding on Episode IX, especially considering how divided fans were over The Last Jedi. Though with Abrams back in the director's chair, it seems likely that the new film will be a return to form. The as-yet-untitled film hits theaters on December 20, 2019.
