One of the studio-based horror projects that I've got my eye on is The Ruins, which is based on a very fine novel by Scott B. Smith. If they hew closely enough to the source material, I'm thinking The Ruins could make for one ferociously memorable little terror flick -- but we'll have to wait until April 4 to find out.

Helmed by first-timer Carter Smith and starring folks like Jonathan Tucker, Laura Ramsey, Shawn Ashmore and Jena Malone, The Ruins tells the tale of an ill-fated trip into the jungle ... but it's NOT your typical hack 'n' slash affair. Trust me on that. Two new posters for the flick gives away a little bit of who/what the antagonist is, but not enough to ruin the fun. Check out that one-sheet right here at Shock, and then head on over to JoBlo's for a peek at the second poster. (Starting to sense a theme in these posters?)

The official site also has a new "red-band" trailer up, and it's even better than the "all ages" teaser that appeared a few weeks back. Ooh, and best of all: The Ruins has been rated R by the MPAA for "strong violence and graphic images," in addition to some other adult-oriented stuff. So to those who were worried that Smith's story would be toned down for a PG-13 crowd, feel free to offer some thanks to Paramount and DreamWorks.
