For its 15th anniversary, this reinvention of the George Romero classic — a terrifying story of the “American Dream” gone horribly wrong — comes to 4K for the first time. In a small Midwestern town, residents turn violent when a mysterious toxin in the water supply turns everyone exposed to it into mindless killers. Trapped in a town they no longer recognize and abandoned by the authorities, Sheriff Dutton (Timothy Olyphant, “Justified”) and his pregnant wife Judy (Radha Mitchell, London Has Fallen) struggle to survive in this nightmarish tale that continues to have a long-lasting impact on the horror genre.
