Brandon Sanderson is ready for the next step of Mistborn's script process.

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.
