Icewarrior (1994)

Not far from the North Pole on Ellesmere Island, for one hundred and twenty days, a watchful camera stalks a beast of fleece and hoof, the ancient musk-ox, in anticipation of the great bull's duel for dominance. By the light of late summer, in the hush of expectation of mating behaviour, battle is joined between the furry combatants.

Unfortunately the movie Icewarrior is not yet available on HBO Max.
