Despite inconsistent box office and mixed critical reaction, Walden Media and Fox seem dead-set on filming all seven books in C.S. Lewis's 'Narnia' series. Although 'The Silver Chair' is technically the next chronological entry in the series, Walden Media co-founder and president Michael Flaherty told The Christian Post that they'll be taking on 'The Magician's Nephew' next, a prequel story and the sixth book published. As Flaherty himself says:
"We are starting to talk to Fox and talk to the C.S. Lewis estate now about the Magician's Nephew being our next film ... If we can all agree to move forward, then what we would do is find someone to write the script. So, it could still be a couple of years."
