Rothfuss welcomed the opening bid for the film rights to his books, even if it was less than what he'd originally hoped.
The first two novels in the series, The Name of the Wind and The Wise Man's Fear, were released in 2007 and 2011 respectively. The concluding volume, The Doors of Stone, is expected in 2016. The imminent conclusion to the trilogy is probably what sparked interest from movie companies after several previous attempts to bring the project to the screen failed.
Warner Brothers, MGM and Lionsgate are believed to be leading the charge for the rights, with Fox and Universal also believed to be interested.
