Josh Randall and Brianna Brown are Mike and Sheryl, a happy couple out for a weekend camping trip in the horror thriller Timber Falls (2007). Things begin to go wrong for the pair when they run into a family of inbred religious zealots who want to capture them for their breeding program. The real horror here is that Knocked Up actress Brianna Brown uses a body double for her boob- and butt-baring scenes. Still, Timber Falls will give you wood.
