Continue to check back with us as we will be adding more information as it becomes available.Brandon Sanderson is ready for the next step of Mistborn's script process. Comprised of two series that began with 2006's The Final Empire, Sanderson's fantasy novel franchise is set on the largely inhospitable planet of Scadrial, whose population is largely situated at the poles of the planet and, in the first trilogy, live in an autocratic dystopian society which a secret group of magic users known as Allomancers fight to overthrow. The second Mistborn series, meanwhile, picked up 300 years after its original trilogy and shifted the focus to Twinborn detectives Waxillium "Wax" Ladrian and his partner Lessie and their adventures. Sanderson has worked with a variety of studios for the better part of two decades to bring Mistborn to life on screen, with the rights eventually landing at Apple TV along with the rest of the author's interconnected Cosmere universe of novels. In addition to the sci-fi fantasy film, the streamer is in the process of developing a TV adaptation of the author's high fantasy series Stormlight Archive. Nearly two months after confirming he submitted his screenplay to the streamer, Sanderson offered a major new script update for Apple TV's Mistborn movie in an interview with Collider. The author, who was also asked about his Stormlight Archive series, confirmed he is still involved with the writing process on both, though indicated that he "will probably have a writing partner" on the latter project. Sanderson went on to confirm that Apple has "given me their feedback" on his submitted Mistborn movie script, which he reveals was "actually secretly the second draft" of the film after he "did a bunch of revisions on the first": Brandon Sanderson: It's actually like the 18th. I think I was on 1.17 when I turned it in. Apple's had it, and they've given me their feedback. So now my job is revisions. I gotta go, and I gotta find a way to navigate getting what they want into the story. Developing... A film adaptation of Brandon Sanderson's epic fantasy novel. It follows a band of misfits with magical powers as they attempt to overthrow a malevolent force that has maintained control over their world for a millennium.
