Corrected entry: Not really a HUGE mistake, but when Ripley finds Newt in her hole the first time you can see lots of boxes laying round with rations or MRE's in them. But later when the female medic is checking her out she says she is suffering from "Borderline Malnutrition" How is that possible when she had so much left over food?
Corrected entry: When Ripley goes to save Newt, she uses a tracking device to find her. However the only data that tracking device gives her is how far away she is from the receiver. It doesn't give any clue as to direction. For all she knows the receiver can be 50 meters above her, 50 meters behind her, 50 meters ahead of her, below her, to her right, to her left, etc, or even any combination of them. Yet in the maze of levels, sub levels, stairs and corridors of the compound she is able to find the EXACT path to the receiver on her first attempt.
Corrected entry: When the marines first arrive, the dropship lands for a few seconds, long enough for the APC to drive off, and no alien jumps on. When Hicks calls Ferro down again, we can see that the dropship is back in the transport's hanger. How did the alien get on board?
Corrected entry: Ripley and the remaining marines had welded and barricaded every way into the Medical Centre to keep the creepy-crawlies out. They checked all the construction blueprints. Yet they never thought to check the ceiling space, which was covered with a flimsy, lightweight grating that wasn't even bolted or welded down - Hicks merely lifts a panel easily with the tip of his rifle. I always thought that was a hoot.
Corrected entry: After the Marines are attacked in the atmosphere processor and regroup in the APC, they surmise that Corporal Hicks is now in command. Wouldn't the pilot of the drop ship be next in line? Wouldn't she outrank Hicks even if she was only a warrant officer?
Corrected entry: When Ripley and the others are trying to figure out what they are dealing with Ripley suggests something is laying these eggs since there must be over 100. But she knows there already are hundreds if not thousands of these eggs so there is no reason to assume something is laying new ones. (01:34:40 - 01:35:15)
Corrected entry: At the beginning of the movie, when Reidecker is discussing Newt's parents' prospecting claim with Al, he refers to them as "a mom and pop survey team" as if he did not know who they actually were by name. However, this remote colony had only 158 members, so they would have all known each other very well.
Corrected entry: In Alien, Kane refers to the eggs as "leathery objects, like eggs or something" but does not say how many. In Aliens, Ripley says in her deposition, "Kane, who went into that ship, said he saw thousands of eggs there. Thousands." After Kane comes out of his coma, he couldn't have told anyone about the number of eggs. When Dallas asks him, "Do you remember anything about the planet?" he just shakes his head no. (00:13:10)
Corrected entry: When Ripley drives the APC into the station to pick up the marines, Hudson is apparently injured since Hicks has to practically carry him out of the alien hive and into the APC. But in subsequent scenes he has absolutely no trouble walking and his only injury seems to be the acid burn on his arm that he got after he made it to the APC. (01:17:10)
Corrected entry: Bishop tells Ripley that she has 19 minutes at the end when she charges off to find Newt, but seconds later as she walks out of the ship the computer voice says there are only 15 minutes left to get to safe distance. Both are computers that would be working from the same data, why would there be such a large discrepancy? (01:50:10)
Corrected entry: In several of the wide shots you can see the screens on the motion trackers don't have their normal 'radar' type displays, they're just blank screens with a blinking light behind them. Two such instances are when Vasquez and Hudson are searching the colony for a life sign (which turns out to be hamsters in a cage) and right after the aliens cut power to the colony. (00:39:15 - 01:36:25)
Corrected entry: In the scene when the marines are making their first sweep of the complex and Hicks says "looks like they bagged one of Ripley's bad guys here," how do they kill the alien? If they used weapons where are they? Why didn't the marines use them when the drop ship crashed and they only had four pulse rifles with about 50 rounds each?
Corrected entry: When the marines look at the blueprint of the atmosphere processing plant, you can see that the plant is a smooth cone or dome like structure. You can also see the structure when the marines first arrive at the plant to look for the mising colonists. But when Ripley goes back to the plant to look for Newt, the structure of the plant changes completely to resemble something that looks like an off shore oil rig with spires and towers and pipes going all over the place.
Corrected entry: When Ripley is in the atmosphere processor, trying to get away from the queen and gunning down drones, the camera keeps tracking the ammo counter, and it gets down to really low...about 9. She then shoots lots more rounds (if the previous speed that the counter goes down by is any comparison), far more than she had the ammo for.
Corrected entry: In the director's cut watch the temperature guages on the remote sentry controls, you only see the temperature change once, regardless of whether the guns were firing or not.
Corrected entry: In the director's cut, the marines had salvaged four robot autocannons with motion-targeting systems, two of which are placed in the access tunnel to the power plant. Right before they close the hatch, Hudson and Vasquez throw in a waste bin to test them; it is shot to pieces. Later, however, these autocannons still have their full ammo load, as seen on the computer counters.
Corrected entry: Towards the end of the movie, Ripley calls down both elevators to escape the Queen. When they arrive, she gets into the one on the right, leaving the Queen to use the one on the left. When the lifts reach the top, Ripley comes out of the one on the left and the Queen comes out of the one on the right.
