Please help me name this horror film [spoiler-free]

Hey all!
This has been winding me up for about a week now :confused:
I remember seeing an interactive poster released for a film that switched between two images
The first was a brunette woman tied with her hands suspended abover her head, looking scared and looking down. She was in a glass box (i think), big enough for her to stand
The next picture was the same woman in the same pose, but up to her neck (or chest) in cement.
I saw it a while ago, i think it was 2009 or early 2010
Does it ring any bells?
