Behind the Walls has an important claim to fame: it’s the first ever live-action French movie filmed in 3D. That’s a lot like being the first ever Polish high jumper to clear 10 feet on a sunny day when the wind was blowing easterly, but it’s a claim to fame nonetheless. Perhaps this new concept art (especially the giant rat) will help that fame along. Of course, having international super model Laetitia Casta doesn’t hurt either. The film focuses on a woman who sequesters herself in order to write a novel who finds a sealed room in the house and begins having nightmarish hallucinations. Basically, it’s the plot from I Spit on Your Grave without the rape. Check out the beautiful concept art for yourself:
