The Revenant takes place in Montana in the 1800s, but most of it could’ve happened any time since the last Ice Age, in any cold part of the earth.
There’s the snow. The wind. The trees. The slow shaggy meaty animals and the quick fierce ones that bring them down.
Men in heavy furs trudge across this landscape. They carry spears and bows. They know the trick of making fire. They catch fish with their hands in the cold river. When a storm blows through, they cut the trees and build shelter.
