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.
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
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.
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."kh1616
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.12o
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.
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.
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.
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.
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.
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.
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.
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.
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)
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.
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.
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.
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.
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.
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.
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.
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.
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
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.
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.Will
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.
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?
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?
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.
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.
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?Will
Corrected entry: The alien is growing much faster than it devours victims, at times even becoming maybe ten times bigger without killing at all.
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.
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.
