It’s Snakes on a Sub! A naïve submarine crewman brings a sack full of the titular poisonous South American pit vipers onto his submarine. Of course, the venomous creatures slither out and wreak havoc on the deep-sea vessel, which carries, not just an international crack team of underwater scientists, but a heavy explosive load the crew may have to use to save their lives. Deftly combining claustrophobic thriller with animal attack horror, this nail-biter has a rich and memorable ensemble cast. But who knows how few will survive, trapped thousands of feet down, when a fatal bite could be waiting for them around every tight corner?
