In 1845, two huge and aptly named ships, the HMS Terror and Erebus, were sent on an expedition to the Arctic to find the Northwest Passage, a century-old dream of connecting Asia and Europe through North America. Now, even when all went well, an Arctic expedition in the mid-19th-century was a pretty horrific affair by today's standards, and, as you can imagine, all does not go well. In addition to the bitter cold, the cannibalism, and the malnutrition, The Terror throws in some hideous creatures from Inuit folk tales into the mix that hunt and maim the poor sailors. At its core, however, this is not fantasy horror. Co-produced by Ridley Scott and starring Jared Harris from Chernobyl, The Terror is unrelenting in the depiction of the hopelessness on board the two ships. Great timing and a pervasive sense of dread make this a must-watch for every fan of period-piece horror movies.
