Well Hollowfox, I certainly can't imagine Pullman as a feature film, but it's not beyond the realms of possibility that it could be made into a children's TV series. Dickens adapts very well for the small screen, and the BBC made a pretty good job of several of the Narnia stories a few years ago. It could, of course, be absolutely execrable, if done badly. It remains to be seen how Tolkien will turn out. I'm generally optimistic.
Incidentally thanks for that URL at the beginning of this thread, excellent site.
