According to a local cinema website, the movie is set to release worldwide on 23/11/2005. (also the same cinema site that stated that Mad Max IV was released in 2004, but anyway)
The next book is July 16th. And I just hope it is better than book 5.
edited to add link:
. Apparently, the movie is going to be released a week earlier but it is still not a totally fixed date. (edited again to add: click on the studio brief news, then scroll all the way down) Edited, Sun Apr 17 07:03:52 2005 by Zieveraar Edited, Sun Apr 17 07:06:13 2005 by Zieveraar
