I learned of this upcoming film only from an offhand comment in a completely unrelated blog post. I'm surprised only that I haven't heard more news about it, not that it's in development: with every Harry Potter book making its way to Hollywood, to tap only the first entry in Lewis' classic fantasy series without considering its sequels would've been unnatural. But I'm concerned at the rate of adaptation. The Potter books progressed rather rapidly, with only 18 months or so between each release. There's twice that between the first two Narnia films, which is a long time for its young cast (which is indeed returning for the sequel) to grow up. Kids age faster than adults, if you know what I mean, so I wonder how long this cast will be feasible. OTOH, the cast of the Narnia books is more mutable than the Potter novels. Future sequels will not contain the same characters, so without resorting to recasting, they can still cycle in fresh, young faces as the series progresses.
It's something to look forward to — as if next month's Potter plethora weren't enough. Which series do you prefer?
