The movie is opening March 11, 2011 and this poster is doing a great job of making me even more curious about it. Gorgeous image and great use of imagery too! Thorny trees? Not only teeth and claws but iron maidens come to mind. Yikes! And something about the tilt and movement of the shapes puts me in mind of a figure -ie. prey- caught via infrared vision...
