Mistborn screenplay progress

Brandon Sanderson said this week that he is 66% done writing the screenplay for the first *Mistborn* movie. (brandonsanderson.com) Sanderson gave the update in a Weekly Update filmed in Atlanta after a signing at JordanCon, where he said the script had reached the “two-thirds mark.” Earlier this month, he had said the screenplay was 50% complete. (brandonsanderson.com) (ign.com) The same update included Dragonsteel Nexus 2026 logistics and Sanderson’s travel schedule: exhibitor, panelist, media, and squire applications are open now, badge-sale details are due later this spring, and he said he was flying from Atlanta to New York before a writing retreat. (brandonsanderson.com) (youtube.com) The screenplay progress matters because Apple picked up Sanderson’s Cosmere rights in January 2026, with *Mistborn* being developed first as a feature film and *The Stormlight Archive* planned for television. (hollywoodreporter.com) (reactormag.com) Sanderson has said he is writing the *Mistborn* script himself full-time and aiming to deliver it to Apple in summer 2026. He also said he will have producing and approval power across the adaptations. (reactormag.com) (hollywoodreporter.com) That level of control has been central to Sanderson’s pitch to fans since the Apple deal was announced. He told *The Hollywood Reporter* in February that he chose Apple because the partnership “felt right” and said he was focused on making sure the adaptation was “done right.” (hollywoodreporter.com) The current plan, as Sanderson described it in February, is a theatrical-style *Mistborn* film first, followed by a streaming series for *Stormlight*. He also said in early April that Apple had given him feedback on what the studio expected, even before reading a finished draft. (reactormag.com) (ign.com) Fan reaction to the latest update has been upbeat, with replies on social platforms praising Sanderson’s plotting speed and arguing that a strong *Mistborn* adaptation could shape how the wider Cosmere reaches the screen. (x.com) For now, the clearest milestone is the number Sanderson put on it himself: two-thirds done in late April, with a summer handoff still the target. (brandonsanderson.com)
