where of course the protagonist *is* superhumanly tough, but has little or no fight training, and his opponent is a murderous psychopath. He mostly just outlasts him; and it’s shot from a high-ish, unmoving vantage point in a corner of the room, as though through a security camera.

I've seen Unbreakable, but I have no memory of this scene, and now I want to rewatch it.

(Most of my memory of Unbreakable, unfortunately, is of being annoyed at the final twist which should have been the third-act twist, damn it.)
