Demonwarp 4K Ultra HD brings a delirious late-’80s creature feature to the format for the first time, newly restored from the original camera negative. Mixing backwoods horror, sci-fi weirdness, and splatter-era excess, the film revels in its anything-goes approach to monster mayhem.
After a brutal encounter with a towering Bigfoot-like creature shatters a quiet mountain retreat, a group of friends arrives months later under the pretence of a weekend getaway. Their trip is anything but innocent, and when night falls the creature returns, dragging victims into the forest and forcing the survivors into a desperate hunt. What follows escalates into a bizarre nightmare involving undead horrors, alien forces, and ritualistic violence lurking beyond the trees.
Based on an original story by effects legend John Carl Buechler and directed by Emmett Alston, Demonwarp stars George Kennedy in one of his most unexpected genre turns. Vinegar Syndrome unveils the film on UHD with a massive slate of newly produced extras, celebrating this cult oddity in its most complete presentation to date.
