Other mistake: In the slaughterhouse scene, after Harrigan has injured the Predator with his shotgun and Keyes reappears, the Predator throws its disc, and severs Keyes in half at the waist. We see his legs flop to the ground, and blood pour from above, but his upper half (torso, backpack and weaponry) mysteriously remain hovering out of sight.
Deliberate mistake: When King Willie is confronted by the Predator in the alley the Predator approaches him cloaked stepping through the puddle of water. You can see his footsteps causing the water to splash up. However, you can see the water splash up and go through his foot. The Predator is only cloaked, not intangible so the water should have splashed upon his foot, not go through. Water against his foot would be visible too, even though he is cloaked.
Question: Right after the Jamaicans kill Ramon Vega and the predator slaughters all of them, Jerry Lambert says, "she (Ramon's girlfriend) never made it". What could she have died of? She was seen walking with Leona Cantrell and didn't seem wounded, and the predator would not have hurt her because she was unarmed. If she were wounded, she would have been checked out by paramedics right away.
Question: Why at the end, after the Predators have appeared before Danny Glover to give him the pistol, do they camouflage themselves again? Being that they're on their own ship, and no hunt is in progress... Camouflaging themselves just seems like the special effects technicians wanted to indulge themselves one more time before the end of the movie.Paul Weston
