What lurks in glaciers and permafrost
Glaciers provide fertile ground for film productions. In “The Day After Tomorrow” the Earth is suddenly plunged into an ice age; “Snowpiercer” presents a futuristic vision of the world, where the remaining humans live their lives on a train darting across the frozen Earth; and the blood-chilling horror “The Thing” deals with an extraterrestrial "thing", dug out of the ice in Antarctica.
