One of the best things about the man behind the expansive Cosmere universe of novels is that he is an open book (pun intended) when it comes to giving updates on the many projects he is actively working on. More recently, these weekly dispatches have included news on Apple's live-action adaptations of Sanderson's work. This week was no different. In his weekly update video on Tuesday, Sanderson started off by sharing progress reports on key projects. When discussing the script for the Mistborn film adaptation, which the author is penning himself, he revealed that the second draft is now at 50% completion. Sanderson finished the first draft of the script at the end of July, just six months after signing an unprecedented deal with Apple to adapt a number of his novels. While that means work on the second draft has been a little slower than the first, Sanderson is also tied up in writing several other novels. A project that the author hasn't shared much information about is the television adaptation of The Stormlight Archive, also at Apple. Sanderson has said he likely won't handle writing duties alone for that project, and shared he's actively on the hunt for a showrunner to helm the series. Still, it doesn't seem like work on any scripts has begun, and Apple and Sanderson appear to have prioritized Mistborn. Brandon Sanderson is still hard at work on more Mistborn and Stormlight Archive books Image: Polygon While this year has seen Sanderson do some scriptwriting for Mistborn, the author is by no means putting his other writing on the back burner. Ghostbloods Book One, the start of the third Mistborn era, is set to be released at the end of 2028, with the second and third books of the planned trilogy due out in 2029 and 2030, respectively. As for The Stormlight Archive, Sanderson recently revealed an ambitious plan to finish up the sprawling ten-book series. Following the completion of Ghostbloods, the author wants to start releasing the second part of The Stormlight Archive (which will consist of books six through 10) sometime around 2031. He aims to write the first two or three in rapid succession, then release them every other year. In between all of that, there are a number of other projects in the works at different stages of development.
