Brandon Sanderson, a popular author of high-fantasy and science fiction books, has signed a deal with Apple TV to adapt his works set in the Cosmere fictional universe into films and TV shows. According to The Hollywood Reporter, Sanderson’s deal with the streaming service is unprecedented, because he will have major creative control over the adaptations. Sanderson’s Cosmere universe encompasses dozens of books set in various but interconnected worlds and timelines. They’re all bound by a single creation myth, which explains where the universe’s different types of magic come from. Apple TV has yet to announce timelines and release dates for the projects based on Sanderson’s work, but The Stormlight Archive TV adaptation already has a producer (Blue Marble) attached to it.
