Corrected entry: Whilst the phrase 'Fire in the hole' may have changed in the future, it is unlikely it would have two separate meanings. For example, the first is when the APC catches fire, (as in fire in the APC) and the second is when Vasquez throws the cannister in front of the sentry guns (the more traditional meaning-i.e. throwing a grenade). Both these phrases have nothing to do with each other, but are still used in exactly the same way.
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: The guns fire 10mm caseless. Each magazine holds 95 rounds (according to the poorly placed counter). A springloaded magazine can only push bullets in one direction, so at most you can have two rounds alternated vertically in a compressed zig-zag pattern. You can't have five rounds side by side in a magazine, as there would be no way of moving them horizontally into the chamber as well as vertically through the length of the magazine. This means that a 100 round magazine would either have to be a drum or cylinder shape like that on a Thompson submachinengun or it would be at least sixty centimetres long.
Corrected entry: When the marines are in the dropship and ready to go to the planet below, the couplers release and the ship literally drops from the Sulaco which is in a gentle orbit. The dropship should have continued to move with the Sulaco in orbit.
Corrected entry: In the scene where Bishop "does the thing with the knife," it appears Ripley is sitting at the end of the table with the rest of the marines. She is watching the events with Bishop and Hudson. However when Bishop sits next to Ripley, she's at a different table and her back is to the other marines. Did I see this right?
Corrected entry: In the final rescue of Newt, Ripley wisely uses flamethrower bursts to make sure the small hallways are clear of aliens. However in all other scenes involving the Incinerators they leave a flaming wash behind that continues to burn for a while (ex. the APC rescue). Obviously the director couldn't have Ripley wait around for the wash to die down so the bursts burn clean.
Corrected entry: When Vasquez cuts a hole in the pipe for Bishop to up link with the mother ship to get the other landing plane, the plate from the pipe falls in to the hole. When Bishop is in the pipe, Vasquez and Ripley place the cut out piece back on the hole to weld it in place. The cut out piece is smaller than the hole. It was cut out from the pipe and should not fit over the hole without falling through. (01:40:20)
Corrected entry: Only six aliens were used for this film, painstaking editing made it look like there were hundreds of them. If you watch carefully, you'll notice there are never more than six aliens on screen at one time.
Corrected entry: During the briefing on the Sulaco Hudson's comment "Someone said alien. She thought they said illegal alien, signed up." was an inside joke. When Jeanette Goldstein was told they were casting a movie titled "Aliens" she thought it was about the U.S/Mexican border. So for her screen test she tried to look and sound as Hispanic as possible. So she was cast as Vasquez.
Corrected entry: In the final showdown on the planet, the Aliens have burst in all around the Ops room. As Ripley is making her way to Medical, Gorman is in the upper corner of the screen, firing his handgun. Watch him, and you will see him point and shoot three times, you hear the clicks, but there is no noise, report or flash, just the actor pointing an empty weapon clicking away, as he apparently hits targets.
