I think people all over get the chills whenever Disney gets their hands on a movie license. It usually means the end of any interest in the subject matter. Their production values have decayed to much under Eisner that expectations are automatically low, and even then we're usually disappointed.
Maybe that's the whole point.
Well, the C. S. Lewis estate folks still have control of the story, and they very much respect its integrity, so Disney can't muff it too badly.
