Is there? All I'd say is that The Horse and His Boy takes place within the timeframe of The Lion, The Witch, and The Wardrobe - other than that, it's pretty much given... To be honest, I wouldn't be surprised if they stopped after the first three films in your first list, maybe The Silver Chair as it's a cracking film story, I just don't see them doing all of the books, though I'd love it if they did. Guess we'll have to wait and see, eh?
