The snakes in SILENT PREDATORS are some nasty critters, to say the least. We first meet them twenty years earlier, when a truck carrying this genetically bred rattlesnake wrecks, and the snake kills its two passengers. Fast forward 20 years and we meet Harry Hamlin as the new fire chief in a small town. Jack Scalia and Shannon Sturges portray the greedy land developer and his assistant who refuse to stop their bombing in spite of unleashing thousands of this newly bred snake. Suffice to say, the snakes do get loose, Scalia usurps Hamlin's power by bringing up a shady past, and veteranarian and Oscar-nominee Patty McCormack spouts out the balance of nature speech. A tense ending in a deserted mine shaft has sufficient chills and overall the cast and crew perform yeomanly. An above average TV movie.
