Corrected entry: In Predator 2, the predator's weapons (spear, etc.) were visible while in use. In AvP, the weapons (for example, the blades on their wrists that they stab people with) are invisible when the predator is. Can't have improved in the few years between Predator 2 and AvP, as the Predators are seen to have similar technology many years before in the pyramid scene.
Correction: There's 14 years between Predator 2 and AvP. A hell of a lot can change in that time. For an example, look how far mobile phones have come.
Also, it doesn't need to be a technical advance. It could just be a style choice by the Predators. Same as real life hunters choosing to paint camouflage on their rifles or not.
Trivia: The Predators in this movie were played by Irish basketball players.
Continuity mistake: When Lex and the predator are going up the tunnel at the near the end of the movie. Lex has the alien head shield on her left arm. But when they are speeding up the tunnel, the shield is not on either arm. If you pause it, you can see the shield missing. When they emerge out of the tunnel it is back on her arm. (01:17:05)
Suggested correction: The shield didn't vanish. Lex removed it so that she could hold the sled with both hands. The shield is right between Lex and the predator. (1:26:58) When they emerge out of the tunnel, the shield is on her right arm.
Corrected entry: Lex makes a big deal out of their destination being a remote island in Antarctica. She says it is one of the hardest locations on Earth to get to. What do they find there? An abandoned whaling station. Hmmm. Not too hard to get to for 1900-era whalers, I guess.
Correction: Just because a whaling station is there at Bouvetoya doesn't mean it was not hard for the whalers to get there. In fact, if it is hard to get to, is it not easier to have a station out there if the whaling in that area is profitable, rather than sending ships there from some further location? (A whaling company wouldn't mind losing a few sailors to dangerous conditions, and judging by all the bones there, I would say whaling on the island was very profitable).
Correction: At no point does she say anything about it being "hardest to get to." She does state it is isolated.
Corrected entry: It was nice for the predators to give Lex the spear at the end of the movie but maybe they could have given her a ride home or some clothing. She was stranded on Antarctica at night with no jacket and a long distance from where the ship was docked.
Correction: When they are on the hunt, Predators are expected to be entirely autonomous. By showing Lex the respect of offering her a trophy, they recognize her as a warrior and would expect her to be able to take care of herself.
Correction: I just finished watching the movie and had this same thought. However, after the Predator ship leaves, the camera shows the Snowcat, which is the proper name for the snow tractor, with its headlights still on. She could have driven back to where they left the ship in relative comfort.
Corrected entry: Lex picks up the Desert Eagle and fires it. The DE is so powerful that even the soldiers who use it have to use both hands. Lex fires it without even blinking.
Correction: It is possible to fire a Desert Eagle one handed, and therefore this is not a mistake.
Correction: She uses both hands and blinks when firing it. Not sure what you are talking about.
Correction: The trilogy has taught us that predators hunt in clans, probably for competition. This could simply be a different clan than in Predator 2, with access to better weaponry.
