Originally, the film was slated to be the fourth in the Chronicles of Narnia film series, as announced at the end of The Chronicles of Narnia: The Voyage of the Dawn Treader, but 20th Century Fox and Walden Media had then decided to make The Chronicles of Narnia: The Magician's Nephew the next film instead. In June 2011 Walden Media's film option for The Chronicles of Narnia was allowed to expire, and a seven year moratorium on producing Narnia films outside Walden Media began. In May 2012 Douglas Gresham stated that The Silver Chair would be the next film produced.
On October 1, 2013 it was announced that the C.S. Lewis company has partnered with the Mark Gordon Company to jointly develop and produce the film. In December two-time Academy Awards nominatee David Magee was hired to write the screenplay.
Joe Johnston was announced as director on April 27, 2017. Filming is expected to take place in New Zealand and begin in late 2018.
