Lionsgate are developing an ambitious, multi-media approach to adapting The Kingkiller Chronicle. They are simultaneously developing a movie trilogy which will directly adapt the three novels - The Name of the Wind (2007), The Wise Man's Fear (2011) and The Doors of Stone (forthcoming) - and a prequel TV series which will explore the adventures of Kvothe's parents. The TV series is in development at Showtime.
Lindsey Beer has written the script for the film, but the real reason things are moving is down to Lin-Manuel Miranda. Having achieved superstar status thanks to his Broadway musical Hamilton, Miranda has made the Kingkiller project his next priority. He is working on the music for both the TV series and films, including the in-universe songs, and is executive producing. With Hollywood keen to tap his talent, interest in this project has sky-rocketed.
The financial success of the novels has certainly helped: Patrick Rothfuss is the biggest-selling debut fantasy author of the 21st Century. The Name of the Wind, The Wise Man's Fear and spin-off novella The Slow Regard of Silent Things have sold well over 10 million copies between them in just over a decade.
However, work on the project may be dependent on Rothfuss releasing the third novel in the series: despite claiming the trilogy was complete over a decade ago and releasing pictures of the apparent manuscript for The Doors of Stone in 2013, the book is still has no release date set.
Sam Raimi is an interesting choice to helm the movie: although his reputation was made in gory horror movies (such as the cult Evil Dead trilogy, its remake and the ongoing Ash vs. Evil Dead TV series), Raimi achieved his greatest success with his three Spider-Man movies starring Tobey Maguire. He also directed Oz the Great and Powerful in 2013 and has been looking for another feature film project since then.
