The creature in John McTiernan's "Predator" was a hunter for sport, preying on anything and anyone with the chutzpah to put up a commendable fight, but to see "Alien vs. Predator" tell it, they were also revered as Gods by ancient Earth civilizations, and were directly responsible for teaching our ancestors how to build great structures like the pyramids. Quite remarkable, if you think about it - in one fell swoop, a screenplay not only manages to build back-story on a famous movie villain, but also solve one of the biggest mysteries of our planet's historical past. If you think that's amazing, then just imagine the surprise of several of the movie's characters, who are recruited at the beginning of the film to be the first men and women to explore the ruins of a newly-discovered multi-cultural pyramid buried beneath hundreds of feet of ice in Antarctica. Some are ecstatic, others are bewildered; but none of them, needless to say, are aware that this hidden fortress is actually an active hunting ground for the Predators themselves, who revive it every hundred years and engage in a dangerous cat-and-mouse game with humans as the puppets. How fortunate for the film to make this great discovery just as the fortress is being revived for another round of bloodshed.
