We’ll never know quite everything about what happened on the set of The Revenant between costars Tom Hardy and Leonardo DiCaprio; what happens in the Canadian wilderness stays in the frozen woods.

Fast forward to nomination season, and yes, Hardy did get a supporting actor nod for his work in the Alejandro González Iñárritu film.
