The beautifully captured wilderness in The Revenant has an animus to it, directing Glass and the others as it wills, and ensuring that retribution is found.
From the opening, The Revenant immerses the audience, ankle deep, into a flooded wilderness. Glass (Leo DiCaprio) and son tread downstream, as if walking on water, and given the constant religious symbolism throughout, I doubt that it’s an accident.
The next scene introduces Fitzgerald (Tom Hardy), the antagonist. From his first moment, he’s pissing in the wind. As a character, his philosophy is at odds with Glass’s more spiritual leanings. He feigns faith, but he doesn’t believe in anything and makes off-hand jokes about a starving man finding God in a squirrel. He finds the concept of a God, other than him, absurd and throughout the film, whether literally or figuratively; he continues to piss in the wind—Go against the flow of the tale.
