The directorial debut of a one Jon Harris, who was Marshall's editor on the original (as well as the editor on the fantastic British face blaster Eden Lake), is angling to mirror the Aliens/Alien sequel dynamic: No one believes Sarah's story of what happened to her friends in that dreaded enclosed space, so back down she goes under the armed escort of inquisitive minds who are all soon bound to get a lesson in why you should trust an ecstatic woman covered with injuries and an unbelievable story about how she got 'em.
The trailer, which debuted officially at IGN (there was an unofficial trailer months ago that got yanked) and is embedded below, makes one thing perfectly clear: There's more people to get eaten and even more pseudo-people to do the eating. Check it out:
Oddly enough that plot line requires the viewer to have seen the American ending of The Descent and not its harsher, original British ending, but hey, a sequel's gotta do but a sequel's gotta do, I guess. Part 2 will likely trot around the globe to a few festivals before settling down for a theatrical run in its homeland this December. I'm sure a US release won't be far behind.
