Writer Brandon Sanderson revealed details of the partnership with Apple TV+, under which adaptations of his book universe, the "Cosmere," are being developed. It was previously reported that the streaming service had acquired the rights to adapt the "Mistborn" and "The Stormlight Archive" series.
According to Sanderson, he considered offers from several major studios and platforms, but ultimately chose Apple TV+ because of the collaboration format. It is a full-fledged partnership, since the company agreed to allow him into key creative decisions.
As part of the deal, Sanderson is serving as writer, producer, and chief consultant on the projects, and also retains the right to approve the cast. Joan Rowling and George Martin, for example, do not have this level of involvement, which became one of the decisive factors in choosing Apple TV+.
The writer also confirmed previously reported information about the format of the adaptations. "Mistborn" is currently being considered as a series of feature films, while "The Stormlight Archive" is planned as a television series.
At the same time, the author launched a public tracker on his website that allows fans to follow the progress of work on the screenplay for the "Mistborn" film. At the moment, the screenplay is estimated to be 2% complete.
