I've been hearing rumblings that "The Silver Chair" is tentatively scheduled for release in 2015 and that the next movie may be "The Magician's Nephew"!
I'm starting to feel a bit uneasy about this. The producers are going to confuse the viewers by not completing the Caspian trilogy (Prince Caspian, Voyage of the Dawn Treader, The Silver Chair) before going forward. I know that they're more concerned with rate of return than the little things that mean something to those whose behinds are in the theater seats but, come on now!
This franchise is NEVER going to be Potter so, don't try to be. Gear your expectations AND budget toward more modest returns and just tell a good story (like C.S. Lewis did) and you'll get the attendance.
