Apple TV has closed a deal for the rights to adapt Brandon Sanderson's Cosmere book series, including the Mistborn series for film and The Stormlight Archive for TV. Sanderson will have significant creative control, including writing, producing, and approving the adaptations.

Why it matters

Sanderson's Cosmere books have a massive global following, with over 50 million copies sold. Maintaining the author's vision and creative control is crucial for successfully adapting such a beloved and complex fantasy universe for the screen.

The details

According to The Hollywood Reporter, Sanderson will "write, produce and consult; and will have approvals" over the adaptations. This level of author involvement is in contrast to other high-profile book-to-screen adaptations, like George R.R. Martin's experience with House of the Dragon, where he said his notes were often ignored. The Cosmere adaptations will start with the Mistborn series for film and The Stormlight Archive for TV, with the production company Blue Marble attached to The Stormlight Archive project.

  • Apple TV closed the deal for the Cosmere rights in 2026.
