No release dates have been announced for either project yet.

Cosmere magic is framed as hard magic with clear rules and limits, potentially setting a new standard for how magic is depicted on screen.

The adaptation approach aims for highly engaging, accessible 10/10 experiences rather than exact 1:1 translations, balancing new-viewer accessibility with fan fidelity.

The broader Cosmere universe extends beyond these two projects, with Stormlight Archive spanning five books and Mistborn across nine novels plus a novella.

For Stormlight Archive, Sanderson plans to write an entire season before developing a pilot, with additional writing partners joining beyond his initial significant contribution.

Apple is developing TV and film adaptations of Brandon Sanderson’s Mistborn and The Stormlight Archive, signaling a major push into fantasy after securing rights and establishing a high-profile deal.

Sanderson will not write the entire screenplay solo, expecting collaboration while contributing a substantial portion himself.

The challenge will be translating Sanderson’s complex magic systems for screen audiences, especially in films where explanations must be condensed.

Sanderson has secured Apple TV rights to Cosmere works, including Mistborn as movies and The Stormlight Archive as a TV series, with substantial creative control and personal involvement in writing and production.

Sanderson will be personally involved, writing the Mistborn screenplay and the Stormlight Archive pilot, with plans to simplify some abilities for on-screen clarity while preserving core powers for fans.

Public progress updates in January 2026 note the Mistborn screenplay is around three-quarters complete after revisions to Act 1.

Clearer magic systems could strengthen action, plot, and world-building, potentially influencing future fantasy productions.
