Corrected entry: When Tom Skerritt first "interfaces" with Mother after being awoken, he says, "Good morning, Mother" - it is not even close to being Tom Skerritt's voice.

Correction: Have re watched the scene and it is Tom Skerritt's voice.

Corrected entry: When the film starts you see the bridge and a stack of papers flap in a breeze.The crew are in hyper sleep and don't need oxygen so it's very unlikely they would have their valuable oxygen supply switched on and turned up enough to make a breeze for the 20 months it takes to travel back to earth.

Correction: The oxygen supply had been turned back on because they were about to wake from hypersleep.

Corrected entry: The doors on the Nostromo always make a hissing sound as they are closed or opened. When Ash tries to choke Ripley with a magazine, a few seconds into this Lambert and Parker appear and try to stop him. However, Ash had just locked all the doors around this location. Even if Lambert and Parker unlocked the doors, a sound should have been heard in the background as they entered the room.

Casual Person

Correction: There was a lot of noise coming from the struggle between Ripley and Ash and we simply didn't hear the hiss of the door through all that noise. Yes Lambert and Parker unlocked the door, nothing strange about that. Ash hearing the door opening wouldn't have changed anything, he would have just kept on choking Ripley.


Corrected entry: In the rapid closeup sequence in which the alien kills Parker (Yaphet Kotto) by biting him right in the face, a freeze-frame viewing indicates that, at the point of impact, a honeydew melon was used to absorb the bite. Now a honeydew melon has a white external rind, and Kotto is a black actor. Why couldn't the SFX guys, at least, have painted the melon to match Kotto's complexion? This production error is, well, in your face. (01:33:35)

Correction: Parker's false head was not a melon but a plaster-cast head with a wax forehead. Inside was pigs or sheep brains. Here's a picture of the effect after filming Parker's 'Head Bite':

Corrected entry: Ripley has just seen Lambert and Parker dead, she has set the ship to destruct, so why does she go down to the basement? The only reason is to show us, the viewers, Dallas and Brett still alive and cocooned and to show us the sticky excretion on the wall, which we see more of in "Aliens."


Correction: After setting the destruct sequence, Ripley realized that Jones, the cat, was being left behind. She went back to find him. That's when she discovered the two other crew members, although that scene had been cut in the original theatrical release.

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.

wizard_of_gore Premium member

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 Ripley is leaving in the escape ship, she's looking out the front window looking back at the ship as she's leaving. When she was prepping the escape ship moments before, the cockpit window is facing outward. If the ship took off nose-forward, she could not see the mother ship moving away through the front window as then she'd be going backwards. There is a small window in the back of the ship through the rear door, but it's far too small to be the same window she was looking out while leaving. Also, the front window has diagonal support struts to hold the windows in place, providing further evidence that the window she is looking through is actually the front of the ship.


Correction: Ripley boards the Narcissus and starts the launch procedure. We see the shuttle being lowered from the belly of the Nostromo, then we see the forward braking thrusters fire [they visibly light up]. This was the effect of slowing the Narcissus relative to the Nostromo, shedding the velocity inherited from the parent vessel. As the Nostromo, which is still under full power, moves on ahead of the Narcissus, Ripley's able to watch it through the shuttle's forward windows. As you say, she could only watch the Nostromo's progress through the forward windows if she was flying backwards. Compared to the Nostromo, that's exactly what she IS doing.

Corrected entry: Several scenes on the story boards and in the script did not make the final cut of the film. Some weren't even filmed at all. Some of these scenes included a sexual encounter between Dallas and Ripley, who have their moment spoiled in horror when Kane's corpse, which they ejected hours before, drifts in front of their view and bangs into the window. The other more controversial scene that was not even filmed, but only hinted at, was a 'rape' scene involving Lambert and the Alien. The Alien sliding its tail between Lambert's legs was originally intended to be the start of a bizarre sodomy/rape sequence, but director Ridley Scott thought better of it and decided not to film that scene. The only inclination of the alien sodomizing or raping Lambert left in the film is the fact that her corpse, which we only get a brief glimpse of hanging from the ceiling, is stark naked.

Correction: The Alien slides its tail between Brett's legs (as can be seen in the extended sequence, or one can notice by the different footwear that Brett and Lambert wear), and that shot was not intended to be part of Lambert's death "originally," but rather as part of Brett's demise.

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)


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: When Ripley goes down to check out how Brett and Parker are doing with the repairs, she says: "Don't worry Parker. (pause) You'll get whatever's coming to you." In the short pause between these two sentences, you can hear Ripley say something like "You have". It seems to be a wrong line which has been deleted, but not properly. (00:22:05)

Correction: Her voice simply dropped out on 'Yeah", as in "Don't worry, Parker - yeah, you'll get whatever's coming to you."


Corrected entry: In the infirmary scene where Ash, Dallas, and Ripley are looking for the facehugger that has detached itself from Kane, just at the moment when Ripley is looking under the table where Kane is lying, Dallas is empty-handed, he knocks something over and gives Ripley a fright and says sorry while at the same time holding a light in his right hand that was not there a second or two earlier. (00:47:35)

Correction: He knocks over the container when he picks up the light.


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".


Corrected entry: At the end of the movie, Ripley signs off as the third officer of the Nostromo. This is a technical mistake - as third in command Ripley would be the second officer behind Dallas, the captain and Kane, the first officer.

Correction: While this maybe true for the current military or commercial shipping, we do not know what nomenclature is used in the future. It could easily be the case that in Ripley's time, they are listed in numerical order. Much like the rank 'Inspector' in US law enforcement has different meanings in various police forces around the US (And is now obsolete in many).


Corrected entry: 1. As captain, why send yourself, the only other pilot (Cain) and the weakest and most timid member of the crew (Lambert) to investigate an unknown and possibly dangerous planet? The better selection would have been Cain, Ripley (whose duties as warrant officer seem to be unclear) and one of the engineers, Bret or Parker. 2. Are we really to believe that the chain smoking and slightly built Lambert could help Dallas carry Cain's limp, space suit laden body thousands of meters, across rugged terrain back to the Nostromo? 3. The Nostromo can navigate itself to Earth through deep space - a navigator is not needed. 4. The Nostromo is just a 'tug' so why does it need a science officer and a lab filled with science equipment? 5. All the elaborate buttons and switches on the bridge and med lab have no labels or designators - how does the crew know what they're turning on or off? 6. Dallas makes two flippant decisions. First, to take off from the planet with needed repairs still underway. And second, to remove the face-hugger from Cain's face even thought it might kill him.

Correction: All character decisions, not movie mistakes. But there are some valid explanations: 1. Lambert's technical abilities were needed to decipher the alien equipment. 2. Lambert carried the lighter end (feet-end of the stretcher), and they likely made several rest stops. 3. Another character decision. 4. A science station doubles as sickbay and is needed in case they run into alien unknowns (like the situation in the movie). 5. Well trained people don't need labels on buttons. For example, expert typists can use a blank keyboard. 6. Not flippant decisions, the ship was able to take off and trying to remove the face-hugger was a calculated risk.

Corrected entry: When Ripley is in Mother there is a moving shadow of a crew member over her right shoulder in the doorway. This occurs after Mother responds "unable to clarify". (01:19:15)


Correction: No error here. Once Mother tells Ripley the true nature of the mission, we see Ash is now seated next to Ripley. The previous shadow movement was Ash sneaking into the room.

Corrected entry: Normally the face sucker alien is helping the host, Kane, breathe. This is evident by the close up shots where the sacs on the side of his body pulsate. In the panoramic shot the sacs on the side of the face sucker are not pulsating.


Correction: NO one ever said they were pulsating specifically to give Kane air. While it's probably giving him air in some other way, the pulsating is probably just the facehugger ejecting the alien embryo into Kane, which it would only have to do for a little while as iopposed to helping him breathe.

Nah, don't think so. The pulsating sacs were helping Kane breathe.

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?

Corrected entry: It's difficult to see, but the instructions for self destruct (at least those for cancellation) appear to be in French. (Although fleeting, this is easier to spot in the cinema than on DVD) (01:34:25)

Correction: While the instructions on the right side of the panel are in French, they are simply translated versions of the instructions on the left, which are in English.

Corrected entry: Ripley was originally supposed to be a male. The decision to cast a woman was done on a lark, and no script changes were made to "feminize" the character.

Correction: Dan O'Bannon's original screenplay never mentioned sexes. All the characters were written to be either sex.

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)

New this month 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.

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 Brett is about to be killed by the alien, a close up shot of just his hat is shown when the alien's teeth impale his skull and his brains come pouring out. In slo-mo you can see that an alien hand is holding his head in place as it strikes. A split second later we see Brett's face, but there is no hand anywhere near him nor is the alien reaching out towards him. (01:07:50)


Correction: No, the alien DOES have its hands on his head. It is on the very left of his hat, and is very hard to see, but it is there.

Corrected entry: When the crew goes into the ship with the eggs in it, you can clearly see that all their gloves are hockey gloves just painted over. Pretty cheap. (00:29:35)

Correction: Just because they look like hockey gloves (and probably were used to make the gloves) doesn't mean they really are in the movie. Maybe in the future, all astronaut gloves look like that.

Corrected entry: When Brett is looking for Jonesy (the ship's cat), prior to being killed by the alien, there is a scene as he passes through one of the doorways when the boom mike is clearly visible in the top of the shot. This is from a video viewing.

Correction: It does look like it's a boom microphone, but it's actually just Brett's shadow. You can tell by watching the shadow that appears on the door right as he approaches it.

Corrected entry: Take a close look at the masks they are using when they remove the helmet from Kane. The masks they are using to prevent contamination are nothing more than ordinary oxygen masks that one uses at a hospital. This is evident by the hose receptor on the bottom of the masks. In reality these masks would not prevent them from catching any airborne disease that this alien would have. I know they are in a infirmary, but a space ship would/should be better equipped in case it comes in contact with other life forms. (00:36:40)


Correction: While these look similar to current masks, they are part of the highly advanced and miniturized technology of the time - they can do whatever they say that they do.


Corrected entry: When the face sucker alien jumped at Kane it only attached itself to the front of Kane's mask. It did not penetrate the mask. When they get Kane to the Nostromo, the face sucker alien is completely inside his mask and there is a big hole that it entered through. (00:36:20)


Correction: The face-hugger used an acidic excretion to burn its way through the helmet visor. The visor can be seen to be warped by the effect of the acid.

Tailkinker Premium member

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."

Corrected entry: When Lambert, Kane and Dallas are on the alien ship, before they find the alien corpse I think, you can see jets of gas coming out of their helmets, which is supposed to be them exhaling. Only Lambert doesn't appear to be breathing. Poor lass. (00:27:00)

Correction: We see her breathe several times during the scene. The times we don't? Well, they were in an exciting, scary, suspenseful situation, and Lambert is not exactly fearless, so it is conceivable that she was holding her breath in anticipation of a turn for the worse.

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.

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?

New this month 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.

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: 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: The director's cut of the movie contains a continuity gap with James Cameron's Aliens. In the sequel, we learn that the eggs containing the facehuggers are laid by an Alien Queen, who is protected by drones and warriors. However, in the director's cut version of Alien, we see that the captured Brett and Dallas being slowly transformed into eggs when Ripley comes upon them as she races for the shuttle. (Even in the theatrical version of Alien, we don't actually see either Brett or Dallas being killed; we just assume they have been when the Alien grabs them.) When asked about this later, James Cameron replied that since the released film version of Alien omitted these scenes, he did not consider them canon and did not feel bound by them.

Correction: This can actually work in either the theatrical version or the director's cut. It's possible that the drones, not being capable of laying eggs themselves, can somehow change a living creature into an egg when faced with a situation where a queen is not around (the first egg created would become a queen, most likely). This would help the propagation of a species with such limited capabilities for growth. Kind of like some frogs have spontaneously changed gender when in a situation where there was a disproportionate number of one gender over the other.

Charles Fraser

New this month Correction: The single Alien being able to create an egg from a human would also explain how the Queen in Aliens even got there.

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.

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


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.

Bruce Minnick

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.


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: 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.

Corrected entry: Why is Lambert the only crew member who managed to get covered in blood? There was even blood on the wall in the background, all the other members were in close around the table and yet their clothes were clean, Parker was even holding on to Kane's arm when the Alien burst out of Kane and yet he also managed to stay clean.


Correction: It's a directional blood spurt that happens to fly in Lambert's direction as the Alien forces its way out. Only the wall behind her gets covered in blood, all the other walls are clean. After the spurt, Ash steps in front of Lambert, so the wall behind him is bloody as well, but it's the same wall.


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.

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.

Corrected entry: Looking back, it's kind of absurd that the Alien wasn't discovered hosting in Kane's body prior to its bursting out of its chest. The facehugger was enveloping his face for quite some time and the medical equipment aboard the ship determined that it was shoving something down his throat. Once it falls off of him, the rest of the crew didn't conduct a thorough examination of him to make sure he's fine before sitting down with him to dinner?

Correction: Ash knew the alien was there all along. When Ripley gets access to Mother she reads Special Order 937 (I think) which states that Ash's prime directive is to bring back any alien lifeform. That is why the android was put on board at the last minute and why he was so unhelpful.

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: In the scene directly after Brett is killed by the alien, when they cut to the crew discussing it Parker seems to discuss the alien like he has seen it but I am not aware of any scene where Parker sees the alien. He makes numerous comments about how huge the creature is. How did they even know that Brett is dead let alone the size of the creature? (01:08:10)

Correction: In the Director' Cut, Parker & Ripley arrive in the bay just after Brett has been taken and find themselves standing under the chains with blood dripping down on them. So they know he's dead. As to comments about the Alien's size, that's probably assumptions about what could drag a grown man up that shaft and dice him. Plus one of the deleted scenes (included on DVD-version) shows Brett's killing more graphically, and as rushing to the scene Parker sees him being grabbed by the now man-size Alien up somewhere. He even gets his shirt splattered with Brett's blood.

Corrected entry: The alien is growing much faster than it devours victims, at times even becoming maybe ten times bigger without killing at all.

Correction: Its metabolism is almost certainly massively different from humans', and in the novel they find rations that have been broken open and eaten - probably applies to the film, too.

Corrected entry: When the Alien emerges from Kane's chest, Lambert is splattered with blood, yet when the Alien runs across the table, you can see that Lambert is clean.

Correction: Just after the Alien has burst out Kane, Lambert does have blood on her shirt, Parker picks up a piece of cutlery and is about to attack the Alien, just as he does this, Ash moves forward with his right arm outstretched and says "Don't touch it" At this point Lambert was behind Ash and you can see she still has blood on her shirt, the next shot cuts in with the Alien moving across the table and that is the end of the scene, Lambert was not wearing a clean shirt as the Alien moved across the table.

Corrected entry: In the beginning, when they are trying to take the creature off of Cane's face, acid squirts out and leaves a hole in the floor. Later, when Ripley and Dallas go in to look for the creature, Ripley looks under the table and you can see a clear shot of the floor, but there is no hole.

Correction: In fact you can see that it has been covered with an upside down plastic tray.

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.

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'.

Corrected entry: If you look at the opening sequence of the Alien film, where the ship "awakens" and begins turning on computers, you will notice a coffee cup that appears and disappears in front of the computer terminal.

Correction: There are two terminals.

Corrected entry: After Kane has volunteered to be in the first group to go out, Dallas says "you too Lambert". After she replies "swell" Dallas says "I'll break out the weapons" - where are the weapons that Dallas is referring to? Why could these not have been used to arm the crew, when the Alien was loose on the ship instead of trying to hunt for it in the air shafts with a solitary flame thrower?


Correction: If they shoot the Alien its blood will leak everywhere, and the blood is highly corrosive so it would go through the floors and potentially breach the hull of the spacecraft. They are trying to herd it with the flamethrower once they realise it is afraid of fire.

Parker: It's a robot. Ash is a god damn robot.



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.
