SPOILER WARNING.
This article contains an absolute crap load of details about the fifth film coming in July. Apparently they're screening crude versions of it for people already, and about halfway through this article, the details get really good.

If you don't want to read the spoilers, it sounds like th emovie will be quite a bit better than the last one for the "it better be exactly like the book" fans like myself. These descriptions actually have me alittle excited.
also, I hate sike.
