Corrected entry: Ramirez throws a grappling hook on to the helicopter that is stuck in a tree. We hear a metallic sound as it hits. However, when he climbs up the rope and reaches the helicopter, the grappling hook gets caught in his clothes for a second. The hook gets easily lifted and then dropped back on to the helicopter without a sound. It even bounces a little, like it's made of plastic.
Corrected entry: When Arnold is sliding down a hill as he escapes the predator, the camera takes on his POV. It shows as it pans down that he will be pulverized by the ground below. But instead he falls into water.
Corrected entry: When the guy with the minigun is shot, it has a forward scene of him falling down and the wound is fairly small. When they flip him over after they've shot the hell out of the trees, it looks like a small comet hit him.
Corrected entry: Why is it, when they are first storming the base, they have been blowing the hell out of it for about 10 minutes, but when Arnie bursts into a room saying 'Knock Knock' there are two guys just playing cards? Don't you think they would have noticed that their base was falling apart around them?
Corrected entry: When the guys are attacking the natives, you see a guy getting ready to shoot someone in the head. He does, but the blood leaves the man's head before he even pulls the trigger.
Corrected entry: Near the end of the film when Arnold and the Predator are fighting and they nearly bump into each other, Arnold hangs on to the underside of the tree bridge. When the Predator walks over it, it sounds like amplified footsteps like he's wearing shoes or something but all through the film when you see the Predator he has bare feet.
Corrected entry: One of the soldiers is stood behind Anna who is knelt on the floor with her hands bound. She picks up a log and hits the soldier in the head and flees. If you freeze frame or look closely, when the log hits the side of the soldier's head, it breaks and you can see white polystyrene or sponge from which the fake log was made.
