According to Brandon Sanderson’s own official website, the screenplay for the long-awaited ‘Mistborn‘ film adaptation has officially reached 100% completion, marking the end of a process fans have been tracking in real time for months. Sanderson chose to write the Mistborn screenplay himself, treating it as his full-time job for roughly five months. Sanderson had originally set a personal goal of turning in the finished screenplay by the end of July, a timeline he’s now officially hit. With the screenplay now finished, Sanderson has said his attention will shift toward ‘The Stormlight Archive’ television pilot, where he’s set to serve as co-showrunner. That means Mistborn fans may need to stay patient a while longer, even as the project takes its most significant step forward yet.
