I haven't read the Scott B. Smith novel this is based on, but I've always been freaked out by creepy-crawlies that burrow under your skin, so this is right in my wheelhouse. Admittely, my hopes for this movie were muted after I first saw the original teaser, but based on the extended red-band trailer this looks to deliver the goods when it comes to the unnerving and disgusting. Unlike Smith's previous adaptation, 1998's A Simple Plan, I doubt anyone will make any claims for Oscar-worthiness for this one, but I'll be satisfied if it's scary, and if nothing else the trailer is encouraging.
