There's a scene in the script of the original that didn't make it into the movie. I think it was Dillon looking for Mac, and Predator is right behind him moving as he moves, playing with him. Dillon stops, Predator stops. Dillon moves, Predator moves. Like those cartoon gags when someone is hiding behind someone. That scene would have added a lot to display Predator's nature. Shame it wasn't filmed.
