A film crew making a porn flick at a cabin in the remote woods run afoul of a couple of deranged and dangerous children. Director Mike Nichols, working from a twisted script by Charles Black and Sam Freeman, relates the gripping story at a brisk pace, does an expert job of creating and sustaining a spooky atmosphere, builds a good deal of tension (the last third in particular is quite harrowing), keeps the tone grimly serious throughout, and caps everything off with a nerve-shredding bummer ending. Moreover, the startling outbursts of brutal and grisly violence pack a pretty nasty punch and the plot about the abandoned psycho kids has a genuinely unsettling warped modern-day Grimm Brothers fairytale aspect to it. The secluded sylvan setting projects a potently upsetting feeling of stark isolation and vulnerability. The sound and credible acting from the able cast rates as another substantial plus, with praiseworthy contributions from Marianne Hagan as weary, aging veteran porn actress Angie, Steve Carey as the brave Billy, Jim J. Barnes as geeky camera dude Chuck, Alana Curry as the catty Vanity, Zoe Sloane as hot young starlet Skylar, Douglas Nyback as nervous novice Dominic, and director Nichols as mean jerk director Eddie. Pretty redhead Amy Crowdis and scrawny beanpole Dan Shaked are truly creepy and unnerving as sicko siblings Patti and Henry. Ian Dudley's slick'n'shadowy cinematography and Matt Sorenson's ominous score are both up to par. A neat little chiller.
