I just spotted this new poster of Sanctum, the upcoming 3D action thriller movie directed by Alister Grierson and produced by James Cameron:

(Click on the poster to enlarge.)

Plot:
“Sanctum follows a team of underwater cave divers on a treacherous expedition to the largest, most beautiful and least accessible cave system on Earth. When a tropical storm forces them deep into the caverns, they must fight raging water, deadly terrain and creeping panic as they search for an unknown escape route to the sea.”

And here’s the movie trailer of Sanctum if you haven’t seen it yet:
