Trivia: Kevin Peter Hall, who plays the Predator, also appears as the pilot of the general's helicopter at the end of the film.
Continuity mistake: Early in the movie, Mac throws the dead green berets' dog tags to Dutch. As he catches them, Dutch has his hand closed in a fist, and the dog tags are hanging to the left. But in the close-up shot where we can read the name, his fingers are more open, with the tags resting in his palm.
Answer: In the shots where we can see what the Predator sees, sometimes when he is focusing on someone or something, we hear a kind of flash noise as he zooms in on the object. When we see the Predator's eyes flashing/glowing, that is when he is zooming in on what he's looking at.
