The Last Winter

The Last Winter is a 2006 horror film directed by Larry Fessenden and starring Ron Perlman. An American oil company is building an ice road to explore the remote northern Arctic National Wildlife Refuge. "The arctic tundra has been frozen for centuries... and so has what lies beneath." The members of the expedition seem to be going slowly mad. This is striking and eerie.

The NYT says,

It’s amazing what you can do with a low budget, an expansive imagination and a smooth-moving camera. (A fine cast helps.) An heir to the Val Lewton school of elegantly restrained horror, wherein an atmosphere of dread counts far more than a bucket of blood and some slippery entrails, the director Larry Fessenden is among the most thoughtful Americans working on the lower-budget end of this oft-abused and mindlessly corrupted genre.

Weird Fiction Review concludes, "What this viewer was left with, at the end of The Last Winter, was a sense of having brought near something elementally numinous, as well as an appreciation for the gifts of Larry Fessenden and his talented cast.. Rotten Tomatoes has a 76% critics rating.
