Apple TV is making a very loud move into fantasy, and it’s doing it by handing over the keys. The streaming service has closed an unprecedented deal to adapt Brandon Sanderson’s Cosmere books, giving the author a level of creative control rarely seen in Hollywood. The agreement covers Sanderson’s sprawling shared universe of novels, with early plans focusing on the Mistborn series as feature films and The Stormlight Archive as a long-form TV adaptation. What makes the deal extraordinary isn’t just the scale of the world Apple is buying, it’s who’s in charge of it. Now Apple TV, already dominant in prestige sci-fi thanks to Foundation, Silo and Severance, is making its strongest play yet for the fantasy throne.
