Looks like this is finally happening. The Chronicles of Narnia: The Silver Chair is in the Works! - ComingSoon.net No news on cast or release date, but here's hoping they get Will Poulter back to play Eustace. If the film does well, the remaining books will also doubtless be adapted. I'd personally like them to get the original (former) kid actors for the Pevensies to play the older versions of themselves in The Horse and His Boy and The Last Battle if possible. Enough time has passed for that to work, I think. Continuity/Fanservice bonus!
