"This is dread man - truly dread!" I've started using this line at work when things go FUBAR, but none of my younger staff know WTF I'm talking about. š
This scene is cinematic perfection. With King Willie implying that the Predator is not of this world, and also hinting that he knows the Predator is coming for him and that he likely has no chance of survival. It really builds the Predator up as this unstopable otherworldly creature.
And then the Predator actually shows up, and you are shown glimpses of it. Just enough to see that the Predator is not human, but you are never fully shown what it is and what it looks like. It shows you how powerful the Predator is while maintaining an aura of mystery around it.
