The BBC produced a TV series, which aired in late 1990. It was the fourth and last of the Narnia books that the BBC adapted for television.
On 1 October 2013, The C.S. Lewis Company announced that it had entered into an agreement with The Mark Gordon Company to jointly develop and produce The Chronicles of Narnia: The Silver Chair, following the film series' mirroring of the novel's publication order (in contrast to Walden Media's initial pushing for The Magician's Nephew during planning for a fourth film). Mark Gordon and Douglas Gresham along with Vincent Sieber, the Los Angeles–based director of The C.S. Lewis Company, will serve as producers and work with The Mark Gordon Company on developing the script.[9] On 5 December 2013, it was announced that David Magee would write the screenplay.[10] In January 2016, Gordon said the film will serve as a 'reboot' of the film franchise.[11] It was announced that Sony Pictures and Entertainment One will finance the fourth film with both Mark Gordon Company and C.S. Lewis Company.[12] In April 2017, it was announced that Joe Johnston would be directing the fourth film.[13]
