The new films will be separate from both the new trilogy helmed by Star Wars: The Last Jedi director Rian Johnson, and the ongoing episodic Skywalker saga. No release window has been announced for the films, and it's unclear if they'll be in the "Star Wars Story" anthology film slate.

“In the summer of 1977 we traveled to a galaxy far, far away, and we’ve been dreaming of it ever since," Benioff said in the announcement.

The duo will get to work on Star Wars once the final season of Game of Thrones, based on George R. R. Martin's fantasy novels, wraps up next year. "We are honored by the opportunity, a little terrified by the responsibility, and so excited to get started," Benioff said.

Lucasfilm's Kathleen Kennedy said that Weiss and Benioff are "some of the best storytellers working today. Their command of complex characters, depth of story and richness of mythology will break new ground and boldly push Star Wars in ways I find incredibly exciting.”
