The Skywalker-centric saga of Star Wars you know and love will conclude in 2019 with Episode IX, but the franchise will live on.
"In the summer of 1977 we traveled to a galaxy far, far away, and we've been dreaming of it ever since," Benioff and Weiss said in a joint statement.
"We are honored by the opportunity, a little terrified by the responsibility, and so excited to get started as soon as the final season of Game of Thrones is complete."
The movies will follow a separate storyline from all existing Star Wars movies, including the upcoming Solo and TV show, meaning they will have creative license to introduce new characters and worlds.
It's an exciting prospect for fans, but also a means for Benioff and Weiss to keep busy after Game of Thrones wraps up in 2019.
They had previously announced an "alternate history" drama called Confederate about an America where neither the Union nor the Confederacy had won the Civil War, allowing slavery to remain legal.
The premise attracted widespread controversy for seemingly ignoring that systematic black oppression still endures, and HBO has yet to comment on whether the project will move forward. Our guess: not likely.
Disney has yet to announce when fans can expect Benioff and Weiss' bold new take on Star Wars.
