It's not worldwide takings as it only opened in Australia and New Zealand today. And in the UK there's a surge in film attendance between Christmas and New Year - and only two kid friendly big films out to compete for the parents' money so it's still got legs over here. It won't lose money (especially given that it's nowhere near DVD release yet) but the question is will it make enough profit for them to do some more films?
Personally, I think the story is far too complex for average film audiences who are used to simpler fare, the old black/white type themes. So I doubt studios will be taking a punt on sequels unless they can dumb down the other two novels to a more simplistic level. Audiences aren't really capable of dealing with metaphysics, Milton and Blake these days
and certainly the final book is far too complex to be filmable under today's standards, unless they aim for the arthouse audience and don't even attempt to make it simple.
