CEO Bob Iger revealed that Empire Strikes Back and Return of the Jedi writer Lawrence Kasdan as well as Sherlock Holmes scribe Simon Kinberg are involved in the spinoff films, set within the sci-fi universe but separate to JJ Abrams's Episode 7 and future instalments 8 and 9.
"We are in fact working on a few stand-alone films," Iger told CNBC. "Larry Kasdan and Simon Kinberg are both working on films derived from great Star Wars characters that are not part of the overall saga.
"So we plan to make Star Wars 7, 8 and 9 over roughly a six-year period of time starting in 2015. But there are going to be a few other films released in that period of time too."

The announcement follows speculation that Disney and Lucasfilm are preparing an individual picture based around Yoda.
Man of Steel director Zack Snyder was also rumoured to be overseeing a Star Wars film based on Akira Kurosawa's Seven Samurai, but he swiftly denied the reports.
Iger went on to confirm that Kasdan and Kinberg are also working with Abrams as consultants on Episode 7, which is being written by Toy Story 3's Michael Arndt.
