Question: One thing that bugged me from a recent rewatch. When Brett comes across the Alien skin that it has recently shed, it in no way resembles what the creature looks like now, and is completely disproportionate with its size a few minutes later when it kills him. Now I know that its methods of 'growing' we are lead to believe are different to those of Earth creatures in that they are more accelerated etc...but if it is following a similar pattern to Earth animals that shed their skin shouldn't it have shed at least ANOTHER skin or maybe two to achieve its near-adult human size? And also why in 'Aliens' were no shed skins in abundance dotted around the place when it is part of the Aliens' natural life-cycle? They don't strike me as the kind of creature that would worry about leaving their shed skin around to cover up their presence?
Question: Is there ANY reason the smaller "lifeboat" ship (think they call it the Narcissus) Ripley evacuates into at the end, couldn't have been used as a lander to travel down to the planet in the beginning too (simply leave the Nostromo in orbit, with or without skeleton crew)? It seems, actually is, much less likely to be damaged in the initial landing, and, for that matter, much easier to take off afterwards (being much less massive). It also would have provided one more layer of quarantine containment for the people who stayed in the lander (who may or not be all the other four, in fact one would probably be just fine (Ripley manages the Narcissus just fine at the end), and it would have been a lot faster for the singleton to simply put on their own spacesuit if/when trouble is encountered, and in so doing, preserve their own personal uncontaminated space). The three explorers and the lander guard could simply see to trouble in Narcissus' sickbay-laboratory, without tainting the three back in the mothership, give Kane first response while taking him up to the main lab on the ship, while giving the orbit people warning to put on their suits/have some form of mobile quarantine ready for him.
Question: Throughout the movie, Ash does a few weird things, such as that jogging motion that he makes in the cockpit and the "poor baby" expression he gives Ripley just before he attacks her. Aside from driving home the fact that he's an android, do these actions have any meaning? (Unless he's being sarcastic, the expression doesn't seem fitting, since he doesn't seem to feel any particular empathy toward humans.) Also, what causes him to suddenly start bleeding? And finally, why does he try to stuff a rolled-up magazine down Ripley's throat? My interpretation is that he's trying to implant her with an embryo, since he also starts making weird gagging noises at the same time; but if that's the case, where/when did he get it?
Question: One of the trivia entries states that Ridley Scott prevented any members of the cast from seeing the chestburster until the scene was filmed so their reactions would look more natural. However I've dug up numerous sources (such as IMDB) that says this is not the case and the cast had indeed seen the creature before hand. Which is the correct version of this story?
