Alien

Corrected entry: Ripley's nosebleed: from 1:17:16 (chapter 14: 'A Confrontation with Ash' on the '99 DVD), Ripley's nose starts bleeding, eventually very noticeably. This is almost a full minute before Ash begins attacking her by throwing her twice, which might actually make it bleed. (01:17:15)

Correction: Actually, Ripley's nosebleed was from when they opened the airlock on the Alien and she and Parker were caught in the decompression. That scene obviously was never filmed but the nosebleed was in reference to it. Also, in a cut scene you see Ripley and Lambert talking with Parker over the intercom where he says the Alien is right next to the airlock, apparently somewhat fascinated with a blinking light on in the door.

2

Correction: This would only be an error if a later scene were intended to show the moment the bleeding is caused by some physical strike, but there's no such moment (and there is the chance that her first shoving match with Ash may have had her head striking his, but it's not a certainty). Still, nosebleeds are commonly triggered by stress in people prone to them. Ripley's nosebleed begins after she learns of the special order (crew expendable) and becomes extremely distraught- and after her physically tossing Ash around (causing his head cut that later drips). She marches off, and in the passageways she can then be seen with the nosebleed.

Corrected entry: When the face sucker jumps at Kane, he only jumps onto Kane's helmet. This is best seen when in slo-mo on the DVD. Having it jump through his helmet, as we are led to believe, would have resulted in some glass breaking and facial lacerations to Kane and injury to the face sucker alien. (00:34:20)

Correction: The face-hugger emits a quantity of acid and burns its way through the helmet visor. The visor is visibly affected - the sides of the hole appear melted, not broken.

Corrected entry: Technically speaking, it is impossible to detect the Alien by micro-changes in air density. This is because the device would constantly be reading the mass(i.e. density) of the air molecules around it, and any movement would set it off, as the air molecules would be moving. Even breathing would set the device off.

Correction: Ash explained the motion tracker with micro changes in the air density. It was deceiving the crew all along. When using the motion tracker. Ripley notices it works differently, an unknown way and says, "Micro changes in air density, my ass."

2

Corrected entry: The scene where the facehugger's acid blood eats through the medical bay's floor was done with actual sulphuric acid stained yellow.

Correction: It actually wasn't. A polystyrene mock up of a floor panel was made and doused with petrol, which dissolved it. Nothing as dangerous and unpredictable as real acids were used.

2

Corrected entry: The escape shuttle used by Ripley and the cat is buffeted by a shock wave from the Nostromo's explosion, a shock wave that can't exist. In space, there is no medium through which a shock wave can propagate.

Correction: It's not a shockwave. She's just blown up a colossal ship behind her - what she's hit by is the vaporised remains of the ship, rushing outwards from the point of explosion.

Corrected entry: In the scene were the Alien attacks the man with the flamethrower in the vents, You can slightly see the clothes of the person who plays the Alien. (01:15:30)

Correction: I have watched this scene over and over again. At no point can you see his clothes.

2

Corrected entry: When the ship explodes, you "hear" the explosion. Space is a vacuum therefore you would not hear the explosion.

Craz

Correction: This is a commonly accepted mistake. Almost all sci-fi movies add the sounds of explosions and lasers to enhance the movie, to make it more exciting. If you have space battles without the sounds, it would be boring, even though it would be accurate.

Corrected entry: At the beginning of the film when they come out of their hibernation chambers, they all get up and are walking fine and a couple of characters are clean shaven. Surly if they were in the hibernation thing for many years they would have grown excessively large beards and also would have been very unstable when walking. Just like in real life where astronauts find it difficult to walk on their return to earth.

Craz

Correction: The hibernation chambers, as the name implies, slows down the body's systems to an extremely low ebb - as we see at the beginning of the second film, Ripley, who has been in hibernation for 57 years, doesn't appear to have aged in the slightest. As such, no beard growth would have occurred. With regard to muscle wastage, the crew needs to operate the ship effectively within hours of awakening, which wouldn't be possible if they couldn't stand up. As such, we can assume that the hibernation chambers were capable, in some way, of preventing this from occurring.

Corrected entry: On DVD version: In the part where the chestburster has bursted and is looking up at the crew you see a drop of blood fall onto it's head. This is after all the blood has finished being sprayed everywhere.

Correction: Have you ever sprayed water on a ceiling. It will eventually drip off. The same thing happened with the blood. It dripped off the roof above the table.

2

Corrected entry: Near the end of the movie Ripley gets into a pressure suit to hide from the alien. During the scene, they cut to a close up of Ripley's face several times. In some shots, you can see the glass of the helmet she's wearing, in other shots, her face is uncovered.

Correction: That's not the glass from the helmet. It's the glass from the door she's standing behind. Sometimes we view her from inside the closet, and sometimes we view her from outside.

2

Corrected entry: When the crew come upon the space traveler in the derelict space craft one of them says he is fossilized. For fossilization to occur the tissue must be replaced by minerals from surrounding materials. That is why fossils are found in the ground. When the creature dies it must be covered with dirt or mud before it decomposes. Over time the minerals in the dirt replace the tissue. But the space traveler is sitting in the pilot chair, completely open to the environment and not covered with anything. Either the crew member is wrong or the writers were.

Correction: The crew are the equivalent of merchant seamen, not paleontologists, so perhaps this error could be attributed to ignorance on their part even if the writers screwed up. The term they should have been looking for was 'mummification' or perhaps 'skeletonization'.

2

Corrected entry: The alien face hugger sacs were apparently suspended and filmed from below, then the film inverted to give the appearance that the sacs were rising up from the floor. When the crew discovers the sacs in the alien ship, a closeup shot reveals liquid running up the side of the sac and then "dripping" up into the air.

Correction: This is intentional. The field in which the eggs are kept is supposed to protect the eggs, therefore not a typical gravity field (or else they would not have survived the crash of the derelict ship) and no other gases, other than what would be needed to keep the eggs in stasis.

2

Corrected entry: When talking to 'Mother' the characters never seem to type enough keystrokes to account for the wording of their questions on the computer screen.

Correction: Who's to say in the future they don't have "short hand" software for quick typing?

2

Corrected entry: The 'chestburster' alien that rips open Kane's chest and escapes is about the size of a 500ml beer can, plus the tail and legs, right? Regardless of how inactive it was, there is absolutely nowhere in the human body that such a creature could hide. It is larger than a human heart. It could not hide in Kane's stomach or esophagus without causing a huge, incredibly painful blockage, and there are no other 'spaces' anywhere where it could go. Where was it hiding, then? It could not hide in the abdominal cavity because its phenomenal rate of growth means it must be eating something - and the only thing available is Kane himself. I think he'd notice. (00:56:20)

Correction: The Chestburster could easily fit inside a human torso, tumors larger than the creature are not uncommon in cancer patients without being visible on the outside. As for Kane not feeling any discomfort when it grows, perhaps the creature secretes some sort of painkiller into his system in its growth phase. That would be a key evolutionary adaptation to allow the Aliens to be born in the first place. Furthermore, it could simply be tapping into Kane's energy reserves (fat and some muscle) the same way Kane would if he was burning energy instead of actually eating the host.

2

That would explain why Kane was very hungry when he awoke and asked for something to eat before they went into stasis.

Corrected entry: The newborn alien that bursts from John Hurt's chest is next seen full-grown, munching on a crew member who is searching for Jones the cat. Assuming that it needs to kill to eat, how did the alien suddenly appear full-size without any nourishment?

Correction: In the script, the Alien was caught eating all the crew's food that it could find in one of the food lockers, so it does indeed eat. One of the crew shot their flamethrower into the locker and the Alien then broke through a vent and into the air ducts. Also, the time between Kane dying and Brett dying was at least several hours. In the cuts scenes you see them first searching for the small Alien directly after it emerged from Kane. They then had to put Kane's body in it's shroud; clean up the awful mess in the dining room' perform the funeral ceremony and finally make the cattle prods and motion-detector. All of that would take a fair amount of time. It's not like the Alien grew to full size in only 20 minutes.

2

Correction: There's one big false assumption there - that the creature kills to eat. The extended cut of the film shows that in at least two cases, members of the crew were taken alive to create new eggs, and in other cases, the bodies are left apparently uneaten. The aliens in the film series have always shown the ability to grow to full size extremely quickly; the mechanism is unknown but it doesn't involve eating other lifeforms as no alien has ever been shown to attack before reaching full growth. The most likely explanation is that the additional mass required is simply taken from whatever the alien finds around it (metal, rock, whatever) and is incorporated into the body structure in some unexplained manner (possibly involving the breakdown of such matter via the acidic blood and its reconstitution in a form that the alien can make use of by some organ within the alien body).

Corrected entry: Haven't people in the future learned from the Titanic disaster? Every ship nowadays has enough lifeboat capacity for everyone. Why doesn't the Nostromo?

Correction: There are numerous reasons why. The Nostromo is not a passenger ship but a deep space cargo ship. The Company cares more about cargo than employees and every lifeboat takes room and resources away from cargo. Having no escape route would be good incentive for the crew to fix a problem rather than abandon ship. And as seen in the second movie Ripley's Shuttle takes 57 years and blind luck to be discovered.

Corrected entry: When Ash tries to kill the semi-conscious Ripley by choking her with the rolled-up magazine, she begins to gag before the magazine even touches her lips, even though there is nothing in her mouth or throat yet.

Correction: Ripley had the paper to her lips and was about to scream, but the paper was already in her mouth just when she made the attempt.

Corrected entry: In the scene where Bret is confronted by the alien in the landing gear bay, we see the alien 'unfolding' from a vent using backward folding bird-like legs. In every other scene the alien has forward bending, human-like legs. (01:07:30)

Correction: You're misidentifying one of two shots. The Alien begins above Bret inside the vent. The tail lowers to the floor first, to act as support for it's bodyweight. The tops of its feet are on the vent's floor at the entrance. Without the tail, it could not hold this position- it would just fall to the floor. It then lowers itself (using the tail), feet remaining on the edge of the vent entrance. When we see the side view of its head slowly lifting, we see its arms lower to reach for Bret. It kills him, then drags him into the vent (his body isn't found when Parker arrives). What you believe are backward knees are either the alien's ankles on the vent edge, or the lowering arms soon after.

Corrected entry: When Ripley is setting the ship's self-destruct mechanism she goes to a panel in the floor. In this panel there are four holes with four screws next to them. When she inserts the first screw she has to manually lift up the cylinder to activate it. It also makes a sound as it is lifted. After she inserts the screw into the second cylinder it cuts to a view in front of her. The cylinder makes the same sound as it raises, but Ripley is not lifting this one. Her arms are doing nothing. When she activates the last cylinder she once again has to lift it up manually by the inserted screw. Based on the design of the mechanism it is apparent that all four cylinders have to be manually lifted, but Ripley does not lift the second cylinder. It lifts itself. (01:35:30)

luchador

Correction: She tugs at the first, but this doesn't mean it needs her to. The second rises on it's own, making the same sound. The third is shown having risen without making the sound like the first two as she screws the last one in. She's never shown pulling the third or fourth, and the fourth is never shown rising. There's no consistency between any two of the four, so we don't know if it isn't shown exactly as it's supposed to work.

Corrected entry: Just before landing, Dallas orders the Navigation lights turned on and we see rows of lights lighting up on Nostromo's belly. After landing, Dallas orders the flood lights turned on and we switch again to Nostromo's unlit belly (that should already be lit up with the nav lights) and we see the same rows of lights turned on again.

Correction: The rows of belly lights are seen lit before Dallas requests "navigation lights". Immediately after the order, the four large lamps at the rear of the ship are on (making those the "navigation lights"). The ship then has a very rough landing, taking significant damage (alarms, gas leaks, failing lights), and the next exterior shot shows all outside lights have gone off. After quite a bit of time (and repairs), Dallas requests the flood lights, and the rows of small lights turn on, which makes those the "flood lights".

Continuity mistake: In the shot of the alien's tail wrapping around the back of Lambert's legs right before it kills her, the floor is different to what it was before, there is water suddenly falling from the ceiling when there wasn't before and her trousers have changed from white to blue. This is because that shot was originally intended to be used when Brett was killed.

Trivia: Ripley abruptly yelling at Parker to "Shut up!" is not in the script. Fans and industry gossip have long speculated that this was Sigourney Weaver breaking character in frustration and she was in fact telling Yaphet Kotto to "shut up" so she can finish her lines. The sequels 'Aliens' and 'Alien 3' both feature scenes where one of the normally cooler-headed protagonists suddenly snaps at a ranting character to "shut up!" in apparent reference to this moment. (01:16:50)

Question: Am I crazy or is there a moment after Ripley has activated the self-destruct where the camera is closely following her as she runs through a corridor, she then reaches the ladder, but the cameraman doesn't stop in time and bumps the camera right in to Sigourney Weaver's back, prompting her to turn and face the camera for a moment with an expression that says "you all right?" before apparently deciding to just continue with the scene and climbing up the ladder. This looks SO blatant to me that I have to believe I am simply misreading this scene because there's simply no way anyone would have left that moment in if it were genuinely a mistake, but I can't imagine what else the scene could be (which is why I'm asking here and not in the mistakes section). Does anybody know what I'm talking about?
