Factual error: Early in the movie, the Predator is standing still while cloaked as an ant crawls across its leg. A rat grabs and eats the ant, then a snake strikes the rat. The snake starts to crawl away, then suddenly senses the Predator and gets startled, rattling its tail. However, rattlesnakes are pit vipers. They see heat. So even cloaked, the snake should have already seen the Predator standing there and known. Predator cloaks do not cloak from heat vision. (00:13:30)
Factual error: The movie is set in the Northern Great Plains of the United States, and the tribe is identified as Comanche, but the Comanche were located in the Southern Great Plains, across present-day northwestern Texas, eastern New Mexico, southeastern Colorado, southwestern Kansas, and western Oklahoma.
