Fans who have wondered whether Disney's upcoming Star Wars films will draw upon the franchise's vast expanded universe of officially licensed novels, comic books, video games and spinoffs received their answer over the weekend: In short, no.

Simon Kinberg, who's writing one of the Star Wars spinoff movies and serving as an executive producer of the animated Star Wars Rebels, seemingly put the matter to rest during an interview with IGN at WonderCon Anaheim.

"You know, it’s not off-limits, and it’s certainly inspiring — I’m working on an animated show for [Lucasfilm] as well, Star Wars Rebels, that will take inspiration from everywhere, but — I know for the movies, the canon is the canon, and the canon is the six films that exist," Kinberg said.

Kinberg also said that for himself, director J.J. Abrams, writers Lawrence Kasdan and Michael Arndt and Lucasfilm President Kathleen Kennedy, the new films are "all about honoring the original movies, and yet wanting to take a step forward, too, and tell a new story."

Star Wars: Episode VII opens Dec. 18, 2015.
