Article about the filming of "Sanctum" in 3D

Here's a neat article (well, an article that links to THE article) about the filming of Sanctum.  What I really find neat is the quote from the producer:

Producer Andrew Wight concludes the paper with : "If 3D is done well, it shouldn't draw attention to itself; it's just part of the story. We're not using 3D as a gimmick. But what it does do, in this kind of movie, is make the audience feel like they're closer to what's going on. They've really got that sense of being there, more so than if you're watching it in 2D."
