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.

Correction: Who said it's oxygen? It could be any inert gas. Nitrogen doesn't support combustion or corrosion, dissipates heat, and can be easily mixed with stored compressed oxygen in the right proportion immediately to the crew being revived.

Correction: The company that owned the ship intended for the crew (without their knowledge) to be diverted to that planet solely to collect one of the aliens. The ship was programmed to wake them up at a specific time and location and it would make sure that all life support systems were fully functional before waking them.

Correction: This happened before the ship received the signal and so they wouldn't have been woken otherwise.

A ventilation system operating a fan would not use up the valuable oxygen supply. At most it would be wasting a small amount of energy, however if there was no air in the ship, the heat from the computers would not be able to dissipate.

Corrected entry: Ripley has just seen Lambert and Parker dead, she has set the ship to destruct, so why does she go to the lower deck? The only reason is to show us, the viewers, Dallas and Brett still alive and cocooned and to show us the sticky secretion 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 the crew split into two teams of three, Ash gives Ripley a movement sensor, which he tells her detects movement in the direction its pointing. However, when Ripley points the sensor at Brett and Parker (who are both moving at the time) it doesn't detect their movement. (01:00:35)

Correction: The motion sensor does not work very well. Ripley even comments on this when she says to Parker "Changes in micro air density my ass." Parker also comments "What's the matter with that box?" when Lambert struggles to pinpoint the location of the Alien while Dallas is in the duct. It has been speculated by some that Ash purposefully gave the crew faulty equipment to impede their efforts to kill the alien.


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: 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: 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.

Also Ash would be the only one that could examine him anyway as he was the only crew member with any medical knowledge.

Corrected entry: The idea for Alien came from a terrible comedy B movie called Dark Star (albeit with a cult following) which had in it an alien that was a beach ball.

Correction: Nonsense. In no way is "Alien" based on "Dark Star" (and 'terrible'? That's your opinion). The two films are totally different in style and presentation. The beach ball alien in "Dark Star" is an annoying little nuisance, nothing like the holy terror of "Alien." In fact "Alien" is probably based on "It! The Terror From Beyond Space!" (1958). Dan O'Bannon, who wrote and appeared in "Dark Star" is on record as saying that he was unhappy with the silly alien in "Dark Star" and deliberately steered away from comic elements while writing "Alien."

Correction: None of the roles in Alien were written specifically for a man or a woman. The writers made note that any of the roles could be filled by either sex.

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

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: 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: 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.


They don't actually know that it's afraid of fire, that is just an assumption made by Ash in relation to most creatures retreating from fire.But as Ash is trying to help the Alien that may not be true in this case.

The weapons that Dallas is referring to is a space age looking pistol, Kane is holding one when he gets attacked by the facehugger.

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: 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: 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 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: 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.

Correction: When Lambert was killed by the Alien you heard her on the intercom and the sounds she was making certainly sounded like she was being raped.

Perhaps, but the notion that an explicit rape scene was planned and then discarded is false. Lambert's fate was always off-screen, and Ridley Scott added some details to suggest the horrifying possibility she may have been raped.

Corrected entry: On the special edition: go to the main menu, highlight special features, press right, and you will get the dossiers for the crew.

Correction: This description vaguely resembles an easter egg from the "Alien Legacy" collection or "20th Anniversary Edition" but the wording for just about everything is a bit off.

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: 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: 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.

Maybe the normal tugs owned by the company don't have a fully equipped science station, but the company would make sure this one did due to the nature of their mission.

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.

Chosen answer: Because Ripley would warn the other crew members about the Special Order, namely that the company's mission was to collect the alien (to use as a biological weapon) and that the crew was expendable. The company assigned Ash to carry out the plan, and being a robot, his only intent is to follow their orders.
