Apple TV Locks Massive Deal for Brandon Sanderson’s Cosmere Universe

Apple TV is betting big on Brandon Sanderson. The streamer has closed what insiders are calling an unprecedented deal for the author’s sprawling Cosmere universe, with Mistborn headed for the big screen and The Stormlight Archive being developed for television.

According to The Hollywood Reporter, Sanderson will serve as architect of the on-screen Cosmere, with rare approval rights and a hand in writing, producing, and consulting across projects. Producer Theresa Kang’s Blue Marble is already attached to executive produce the Stormlight series for Apple TV.

Inside a Rare, Author‑First Hollywood Deal

The Cosmere deal follows a fierce bidding war that reportedly saw Sanderson meet with most major studio heads before choosing Apple TV. The agreement grants him a level of creative control that industry watchers say surpasses what J.K. Rowling or George R.R. Martin enjoy over their franchises.

That power didn’t come out of nowhere. Sanderson has sold more than 50 million books worldwide and built one of the most dedicated fanbases in modern fantasy. He famously used crowdfunding to sidestep traditional pipelines, raising over $41 million in 2022 and another $14.6 million in 2024 for Cosmere-related projects, including surprise novels and special editions.

Those readers have followed him beyond the page, too. A Cosmere tabletop RPG based on The Stormlight Archive became the most‑funded RPG in Kickstarter history in 2025, expanding the universe into gaming well before this screen deal. We’ve already explored how the game “rewrites the rules” for fantasy tabletop play in our Stormlight RPG deep dive, a move that now looks like a dry run for even bigger cross‑media plans.

From Scadrial to Roshar: What Could Hit Screens First

The first projects in development are a film series based on the original Mistborn trilogy and a prestige TV take on The Stormlight Archive. In Cosmere terms, that means metal‑burning thieves toppling a tyrannical empire on Scadrial, and storm‑scoured wars, knightly orders, and monstrous Voidbringers on Roshar.

But Apple’s rights reach further. The Cosmere also encompasses standalone touchstones like Elantris and Warbreaker, as well as newer stories such as The Sunlit Man. Sanderson is already deep into the books’ future: 2024 brought Wind and Truth, the fifth Stormlight novel, and he’s actively developing Mistborn Era Three—nicknamed “Ghostbloods,” set roughly 50 years after Era Two.

On the franchise side, this moment has been a long time coming. DMG Entertainment first optioned Cosmere rights back in 2016, but those attempts stalled. Sanderson has said he turned down multiple offers over the years while trying—and failing—to get a Mistborn adaptation he could fully support. He’s spoken before about wanting his worlds to become larger multimedia empires, but only on the right terms, a tension we unpacked in our look at Sanderson’s multimedia ambitions.

Why Fantasy Readers Are Paying Attention

For years, the Cosmere has been the great “what if” of fantasy adaptations: a carefully interlocked universe of magic systems, worlds, and cameos that seemed tailor‑made for a long‑running screen saga but repeatedly stalled in development. Apple TV’s all‑in commitment—and Sanderson’s unusually high level of control—may finally convince skeptical readers that a faithful, richly serialized Cosmere on screen is actually possible.

With a record‑breaking fanbase, a thriving convention circuit, and a 2026 slate packed with new books, RPG content, and even AAA video‑game talks, Sanderson’s universe was already expanding fast. Now, with Apple TV in the mix, the Cosmere looks poised to become fantasy’s next major cross‑media powerhouse.
