Unsettling isn't the same as loud. The performances that linger are usually the ones that treat menace as concentration — a man who has already decided what he will do, and is only waiting for the world to catch up. Three is enough. Padding a fourth would dilute the point.

Javier Bardem in No Country for Old Men (2007)
Anton Chigurh is what happens when fate gets a haircut and a cattle gun. Bardem plays him with almost no interest in your fear — which is why the fear works. The coin toss isn't a quirk; it's theology with spare change. On ActorRating, this is a supporting performance that behaves like a weather system: everyone else is reacting to the pressure drop.
