Egg silo exterior

leading from

a) Where Ridley had been going
Ridley Scott had been experimenting with the idea of an egg silo inspired by the Castle Harkonnen,
and had been exploring the idea of a giant rocket capsule shaped derelict ship with Moebius before he left.  (see: Moebius derelict exterior and Ridley Scotts Early Egg Silo Exterior )

Ridleygram of structures on the planetoid (image from weyland-yutaniarchives)


b) What Giger drew
HR Giger designed a breast shaped building called the Egg Silo, a hundred and fifty metres tall and two hundred metres in diameter.  He drew the images in April of 1978. Perhaps he borrowed the shape from Ridley's early idea for a derelict ship that he work on with Moebius. It also included ideas from Giger's painting Dune I which showed an entrance to the Castle Harkonnen.

c) Giger's Painting
In the painting, in the rock formations, suggestions of perhaps long fossilized life forms. Perhaps the  rock sticking out of the lower ground to the left of the building is a half formed impression of Cthulhu type entity with its tentacled face and thick claw. Giger had brought his designs at the time over to Shepperton for approval on March 30th of 1978, although they were met with general approval, he is told that his egg silo would be too expensive to build.

HR Giger's Egg Silo Interior version I

 leading from


a) Reaching the first version
By 19th July, 1978, Giger's concept for an Egg Silo interior had evolved. This became version 1.
The egg wagons that had scooped up the eggs and transported them along a rail to the pipes had disappeared, along with their monorails, they had now been transformed into big pregnant capsules on the wall of the silo which Giger had decided were symbols of fertility. Above the capsules were entrance tubes coming down at the side rather than in the centre of a circular buildings, and a space for the hieroglyphics painting to be seen. (see also : Placement of Life Cycle Tableau )

Work 386 Egg Silo version I
b) Echoes of Foss
After comparing Chris Foss' elongated derelict ship and Giger's Egg Silo version I painting, it might be easy to assume that Giger had taken the general form of Foss' derelict as a starting point for the painting, and now the two slit windows on the pod from Foss' derelict that had translated themselves into a slightly different form in one of Moebius' earlier derelict designs has almost seem to crawl into Egg Silo version 1 as two slit like eye like spaces above the pod, or maybe such abstract bilateral forms protruding from the tops of various of Foss' structures that might be such things as engines or something similar to two rectangular radars fused together that might make one think of robot eyes or visors ( See Chris Foss' Alien temple interior and Chris Foss' derelict, 
and Moebius Alien spaceship concepts part 2)

Source Quotes
  1. HRGiger:19th July 1978, Shepperton Studios. Luckily the wretched idea of only having six eggs has been dropped. Scott somehow managed to persuade O'Bannon, or else he's simply acted on his own authority. The victory is followed by another defeat. During my absence someone has attacked me in the rear and had decided to do away with the big "pregnant" capsules (plate 386), the symbol of fertility in this set. The reason: ' They're superfluous." Superfluous? When Voysey, who has to be working in five places at once, has prepared a scale mdoel in meticulous detail (plates 386d and e)? I suppose I shall never master the secret of how such decisions are taken. It is getting clear to me that my creative capacity is slowly but surely being numbed. I'm still convinced that the best critic of an artist's work is the artist himself. (Giger's Alien, p44)

a) The vast temple interior created by Chris Foss had the look of something that was created for giants. The explorer lowers himself from the shaft above above a plinth that might be as large as a three or four story building and perhaps it looks as if it could easily be an oven with a kitchen chimney above it.

egg wagons (1)

a) Segmented Circular Container
Drawn on the 19th April 1978, early in the production, HR Giger's first drawing for the egg silo, was a circular container, divided into segments of equal size by rods running from the top of the wall to the mid-point of the floor, and each segment was filled with eggs


Egg Wagons (2)

b) Entrance Tube
An entrance tube made from a membrane hangs down from the ceiling, with tubes down the the side. Perhaps an egg is seen to fall from the central tube in the first picture. 

c) Egg Wagons
Little egg wagons with scooper like devices run along a monorail made from the dividing rods and up to the ceiling along the partitions in the building.The wagon swivels around, and a tongue like device extends from it, picking up the eggs and holds its within a container before running up along the wall and up along the arch of the ceiling to deposit it in an opening at the top of an egg tube.

Sex and the Alien

fish eye lens photo of the Narcissus set during filming

a) Questions about nudity
Originally, in the scene where the crew rise from their cryotubes, everyone was naked, and one of the things that Sigourney thought was very interesting about the film, coming from her theatre background, without thinking about the markets, the Catholics, ratings and censorshop, was this very striking idea about pink vulnerable creatures moving through a very hard metallic environment, it offered a nice contract and this was not shot because Fox said " We'll lose Spain and we'll lose Italy, so you have to wear cloths". But still there was this idea of filling as much flesh as possible within the environment to show what a human being was, in space. Sigourney did realise it was erotic but it was something very important.

b) The Strip
So the other side of the fourth act is the fact that Ridley stripped the Ripley character down, Sigourney Weaver in the part is strong, capable and attractive and he wanted to increase the sense of her peril by showing her undressed, Ripley does a modest strip down to her underwear. It not only made this ballsy sort of lady vulnerable - but sexy too. Sigourney's understanding about the intentions behind the strip was that it wasn't about sex, not for her or for Ridley either, and Ripley  obviously didn't want to go into hypersleep covered in blood and god know what else, she just wants to take her clothes off and have a bath, also she is relaxing, thinks it's over, goes about her business and suddenly the worst possible thing happens, she's not prepared and is vulnerable as can be.

Later she would have people say to her ‘Aw, how could you demean yourself by doing a striptease?’ 
And she would respond ‘Are you kidding? After five days of blood and guts, and fear, and sweat and urine, do you think Ripley wouldn’t take off her clothes?’"

It never occurred to her for a second that people would think that her strip was exploitative. However she thought it was provocative

c) Possibilities of the alien's sensuous nature
Ridley appeared to Sigourney to have thought that there were great erotic possibilities for the scene in which the alien comes out of its hiding place to watch Ripley in the closet as she's shedding her clothes, perhaps as if she was a snake shedding its skin or just another creature suddenly removing its shell, so that it looked as if she was going from a dark green and crusty looking animal in her clothes to a pink and white, soft animal. 

Because it saw skin, the alien would not attack because it was being drawn to her, finding what she was doing amazing and it would be moved or emotionally touched in some way, perhaps with sexual fascination, and because she was so different to itself. She was thinking along the lines of the idea of beauty and the beast.

So she discussed on the set the possibility of this creature watching Ripley with voyeuristic passion, but on the other hand Sigourney knew that the Alien was resting. As an actress she remained inspired to think about the alien’s sensual side, (and found in the later Alien sequel, Alien Resurrection, eighteen years later a way to experience a kind of a sexual interaction with the alien creature in one of its manifestations.)

Ridley and Sigourney had also discussed an ending where she is still dressed and is surprised by the alien, so she would run into the closet, take one suit off and put another one on and there would be the moment where the Alien would see her in between suits and be fascinated, because the Alien wasn't evil, it just followed its natural instincts to reproduce through whatever living things were around it.

After the movie, every now and then a reporter would ask "How could you have been part of a film about such evil?"

And Sigourney would respond  ‘Good Lord! You take this very seriously, don’t you?’

d) Further questions about Sigourney's point of view
From Ridley's point of view, he only tended to talk about an interest in the erotic possibilities of Ripley shedding her clothes rather than have a point about what the Alien was thinking in a sensuous way. He further looked at Sigourney Weaver's idea some years later in hindsight, and thought that perhaps she has a touch of sympathy for the creatures because she looks at it from the viewpoint of her character. Ripley was part crew member and part scientist, someone who thought in logical terms. And maybe at that moment, her scientist side emerged and she began to study the creature like a scientist would and started to get a perspective on what it may have been thinking and previous to this scene, one should remember that there had been absolutely no communication between the alien and the crew members, other than violent experiences, but Sigourney was aware that they always wanted an erotic undercurrent in the film, where the audience might ask "What would it do to her?"

e) Questions about nudity
Sigourney felt that since the creature had been naked all the way through the movie, she at least ought to find herself completely naked before this creature at the end of it all, but this didn’t go down well with the studio bosses concerns about selling the film to Catholic countries, so she went ahead and wore her underwear which she thought was a cop out. However, she felt that seeing what kind of response she was going to have from the audience, she thinks it was just as well she had some clothes on as since then she would think twice about taking off all her clothes in a movie and scampering around for an hour.

f) Smallest Pair of Knickers
They were looking for a pair of knickers of Sigourney to wear back on the set, they held the shoot up by a couple of hours, the first pair that the costume designers came back with looked to Ridley like a pair of diapers, he wanted something very sex and so he went himself to find something and whatever the smallest pair were, those he came back with. Sigourney was a tall healthy woman with long legs who did a lot of running. Ivor Powell was impressed by how sexy they made her look. However Sigourney wasn't thinking about this being the scene where she shows her underwear, she was trying to present the most utilitarian knickers she could find.

g) White Knight vs Futuristic Dragon
The last twenty minutes are treated in a very lyrical style, Scott sees this as a reflection of the way he looks at reality. Ripley is happy to find a space suit and puts it on. so she can get on with what she needs to do. It was more than whether Ripley will triumph, it becomes a situation with an undercurrent of sexuality where she dons the virginal white space suit and she takes up a fight with a futuristic dragon.

Source Quotes
  1. Danny Peary: Was there discussion over your famous strip toward the end of the film?
    Sigourney Weaver: Originally there was going to be a lot of nudity in the film. Of the matter-of-fact variety. There were going to be lots of shots of naked people walking around, which I thought was a good idea because it was such a harsh environment. It would have been a nice contrast. As for my strip… people have said, "Aw, how could you demean yourself by doing a striptease?" And I say, "Are you kidding? After five days of blood and guts, and fear, and sweat and urine, do you think Ripley wouldn’t take off her clothes?" It never occurred to me for a second that people would think my strip exploitive. I think it’s kind of provocative – you’re almost seeing me through the Alien’s eyes. Suddenly I go from dark green animal to a pink and white animal. Ridley and I had so much fun working out the ending. There were so many different endings. One of them was that the alien would surprise me and I would run into the closet where I’d take off my suit and put on another. So there would've been a moment when the alien would see me between suits and be fascinated. Because the alien isn’t evil. It’s just following its natural instincts to reproduce through whatever living things are around it. Every now and then a reporter would ask, ‘How could you have been part of a film about such evil?’ And I’d go, "Good Lord! You take this very seriously, don’t you?" So I liked all this stuff. You see the Alien in its birthday suit the entire film; so I thought it was a cop out having me wear the underwear, and not stripping entirely. Fox is always concerned about losing Spain, losing Italy, etc. But I must say, having received the mail I have, I would now think twice about taking off all my clothes in a movie and scampering around for an hour. (Omni screen flights/screen fantasy,, Playing Ripley In Alien p162)
  2. Sigourney Weaver: Ridley thought there were great erotic possibilities for that scene which the alien, watching Ripley go from green and crusty-looking to something pink and soft, would find amazing. But face it, if you were in that situation would you want to go into hypersleep covered and in blood and god knows what? She just wants to take off what she’s wearing and have a bath  (Photoplay - v30 n12 December 1979)

  6. Interviewer The Last Twenty Minutes are treated in a very lyrical style.
    Ridley Scott: This is how I like to look at reality. It's not simply a question of knowing whether or not Ripley will triumph. I wanted to introduce another dimension. She takes up the fight against some futuristic dragon - that's why I made her put on the white spacesuit. At the same time, this has something carnal. She is possessed by the idea of this confrontation and her behaviour changes completely. (Films Illustrated, vol. 9 no. 99 , "Duelling with Death")
  7. Ivor Powell: I mean, I remember Ridley, 'cause again, this is with his , like commercial hat on, before we shot that sequence, we like held up shooting for a couple of hours where I set out one of the costume designers to go, 'cause the first pair of knickers that they turned up with for Sigourney to wear, as far as Ridley was concerned looked like a pair of diapers and they weren't sexy enough, so we all waited while he went out and came back, and whatever the smallest pair were, those were the ones that got chosen as you can see etc, I mean, Sigourney's a , you know was a very healthy girl, and big sort of legs, she did a lot of running, etc, but they made her look amazing, sexy, and the whole thing was this undercurrent of sexuality and that end sequence of her changing into that virginal white space suit, and then now the alien Wayne Imms: yeah, yeah, absolutely Ivor Powell: All of that, talk about Freudian. It was beauty and the beast really., so. (Alien Q &A, Genesis Cinema, August 23rd 2014)
  8. Sigourney Weaver : Originally, in the movie, everyone was naked, and one of the things I thought was very interesting about the film, because, again, I was coming from theater, I wasn't thinking about markets and Catholics and ratings and censorship, was it was so striking to think of these pink creatures, very vulnerable creatures, moving through this very harsh, metallic environment. That was in the script at the beginning. We didn't shoot it that way because Fox said "We'll lose Spain and we'll lose Italy, so you have to wear [clothes]."  There was still this idea of filling as much flesh as possible within the environment to show what a human being was, in space. I think it was erotic but that was something I thought was terribly important. Not the girl strips down, but the girl relaxes, thinks it's over, goes about her business and suddenly the worst possible thing happens and she's not prepared, she's as vulnerable as she can be. And happily she finds this space suit and puts it on, so she can get on with it. But it was not about sex to me, and I think, to Ridley. Although, again, we always wanted an erotic undercurrent in the film, because [you'd think]  'what would he do to her?' So that was the genesis of the idea. I was all for it. I didn't even think 'this is a scene where I show my underwear.' I was trying to show the most utilitarian underwear I could find." (Alien The Archive, p96)
  9. Fantastic Films: How did you feel about the scene on the shuttle where Ripley doffs her clothes not knowing the alien is on board
    Sigourney Weaver: What could be more natural that to take off sweaty things I was wearing, like a snake shedding its skin. Actually there was some nudity in the script in the beginning of the movie. When we all wake up, we're supposed to be naked. It was a very provocative visual concept to see these people moving through such a harsh environment in just their natural state. But that was changed later. (Fantastic Films #11:, p35)
  10. Ridley Scott: Ripley does a modest strip once in the shuttle, but we kept that in to stress the vulnerability of a lady who's pretty much a ballsy sort. (Cinefantastique, vol 9, no.1)
  11. Questar: There is unusual sexual bias presented in Alien.

    Sigourney Weaver: I think the creature is very sensuous, Ridley always referred to the alien as "he". At one point when we were discussing the scene at the end where Ripley is shedding her clothes, there was an idea that came up which relates to this sexual fascination - but we discussed the possibility of this creature watching Ripley with a voyeuristic passion. The alien would not attack because it was fascinated by the fact it suddenly saw skin. To see another creature without its shell would move it, touch it in some way. We talked about things like that (Questar magazine #5, November 1979)
  12. Sigourney weaver: I think there was [a romantic element] from the very first. The alien coming out of its hiding place and seeing this pink creature in the closet. Ridley really wanted to go in that direction – that it was drawn to me because I was so different to it. Sort of beauty and the beast, I suppose. That was such a strong image to me at the time, it is so sexual; I've never been able to forget it.(http://www.theguardian.com/film/2014/jul/25/sigourney-weaver-fifth-instalment-alien-saga)

One More Surprise Ending

Leading from
Alien: Making the Movie   


a) This is not where the story ends
The film was meant to be over when she goes inside the escape shuttle, takes off, signs off and even with the big bang behind her, that was sound and mixing between three cards and a wobbly camera and he was supposed to sign off there. Ridley felt he simply couldn't end the film here "No way, you can't do that, you canna possibly end there"

b) O'Bannon's original ending
Originally Dan O'Bannon had included an ending in the script where the alien was going to be blown out of the Narcissus with Ripley trailing after it. Ridley felt that it was an outrageous ending but he thought it was wonderful. He thought it had to happen but only if it could be done believably real, in a way that it was so outrageous that it would make you want to cheer and clap

c) Ridley's plan
So the actual end of the movie almost never got made, and there are a few stories about what would have been there right at the end. But Ridley's thoughts went with reintroducing as much of O'Bannon's ending as possible in a way where Ridley would close the lid on the story and then let it out again so that when Ripley goes into that shuttle, there's a moment when the audience knows that the film isn't over when you're sitting in the seat.

d) Fourth Act filmed in Four days
He told the the studio bosses "I wanna spend X to give you a fourth act. "

They replied "How much? 

He added "it'll take us four days"...  

They replied "Four Days!" 

Ridley responded "you really don't even know what I'm going to do yet, let me explain to you what I'm going to do, then you'll go "how can you do that in four days?" as opposed to "four days!" 
We're not finishing the film when she jumps in the shuttle, there's a fourth act,"

They said "what do you mean, the film's over when she jumps in the shuttle and takes off and bingo!"

But Ridley's next response was "no, there's a fourth act in there that will change the way films are made"

And you know, the big bang's then are not the big bangs we could do today, but you know what, today it'd be CGI, this is all real inside the... inside the studio on the set which is you know, only firewood. Okay so this is all design as the end of the movie. So there's a one megaton thing going to go off in a second, and graphic design, interesting uh. Just a flat card , nothing happening, (01:39:00) it's just the sound and mixing between three cards, and I figure you've got to have two or three, but this, I've go... I've got the wobbling down now pretty good. Nobody's really wobbled the camera 'til this moment you know I remember til that, so I'm literally wobbling the camera. Bit unsure about the red ball. (1:43:00) And score. Now, this would be the end of the film. But that.. that's it, you would do a signing off there, and I had to say "no way, you can't do that, you canna possibly end there"

    (1:39:44 / 1:43:30) Sigourney: Aah, Wow!

    "How much? 
    And I said well, "it'll take us four days"...  
    "Four Days!" 
    I said "you really don't even know what I'm going to do yet," so I said, "let me explain to you what I'm going to do, then you'll go "how can you do that in four days?" as opposed to "four days!"(01:40:00). I said "we're not finishing the film when she jumps in the shuttle, there's a fourth act," And they said, "what do you mean, the film's over when she jumps in the shuttle and takes off and bingo!"
    I said "no, there's a fourth act in there that will change the way films are made" because at at , I think until this moment, it's almost fair to say, there's probably going to be some small independent film saying to me "you know, you're full of bull", but you know, today we've got an interesting idea of "now, the end, then the end and then the end, and by the way here's the other end", right and I always wanted to close the lid and then suddenly let it out again, babbam, okay. So when Ripley goes into that shuttle, there's a moment when you know that the film isn't over where.. when you're sitting in the seat.(alien anthology/quadrilogy A;ien commentary)
     

Alien: Life cycle of the alien

leading from

a) Short Lifecycle
Ridley went along wth the idea that alien creature has a limited lifespan like that of the life cycle like that of a butterfly or an insect. He wanted it to have a sort of timelessness. The thing that came out of the egg, the Face Hugger which was also known the "perambulatory penis", is the father. It is an abstract entity, in a sense, because all it does is plant a seed, and once having conceived, it dies.
Once it jumps out of the egg, it has to reproduce and spread as fast as possible, maybe in a cycle of perhaps only four days

b) Genetic traits
The alien creature lived to reproduce and so what the next generation would be doing would reflect that.

Once the derelict and the silo had been merged together the scenario was that a Space Jockey was infected and the spores in the basement of the derelict were what became of the other crew of the derelict.

However perhaps the idea of what the alien life form was doing as a concept was still evolving. One concept that Ridley talked about was that the next generation that followed the Face Hugger was the result was a combination of the original creature and whatever host it uses.

Ridley also talked about how the next generation took on the characteristics of its last inhabitant and its new host, so in effect, the creature known as Kane's son had the space jockey as a grandparent and took on some of its features. The host is in effect the mother even if it is a male

So in that way,  if the Face Hugger had hit the cat, it would have been a hybrid of the Space Jockey and the cat, if it could have been a dog, there would be a dog version of the alien. If it impregnates a man, the you get a man version of an Alien. Eventually the idea became that the space jockey was the pilot of a vessel that had been carrying the spores in its hold since the start of the journey.

c) A further dimension to the beast
And so Gordon Carrol and Ridley talked about it many times, should they indicated that the alien has intelligence , perhaps even great intelligence. Was it just a sort of a time bomb or even just a war machine?

Perhaps it was another form of society adjusting itself like ants, and as Ridley understood, ants had no sense of beginning or end, which goes back to his idea about the alien having a sort of timelessness.

Perhaps they were just born, run around doing this thing like everybody else in the community and then dies, and Ridley thought that this may have been the alien, and if that is so, then the alien had no intelligence except pure intuition about survival.

But there was the added question of what would you have if you're given the fact that this creature that's making use of a man's brain capacity.

Ants

d)  Getting on with its lifecycle
This idea helped explain why the Alien didn't attack Ripley in the Narcissus, when Ripley kills it, the idea was that it would have died anyway.

Like a chameleon, it had found a protective corner in that ship and was working itself in there to die. It has to be provoked to attack because it had to get on with its life cycle.

Slime emanated from its body as if it were sealing itself in again like a cocoon, and perhaps it was transforming into a chrysalis, it's physical volume would decrease and it would transform into an egg and hibernate again.

This might seem to be a strange direction of thought because when humans become spores, Ridley talked about them being eaten away by the alien young and so grows the spore.

Does this mean the alien becomes consumed by its own biology in a similar way?

  1. Ridley Scott: The thing that I was always frustrated about was the absence of sense of smell with the beast. It's a real element with him, because his odor must have been incredibly powerful. I wanted a sense of a timeless, slightly decaying creature that, maybe, only has a limited life cycle of, maybe, four days like an insect. The alien life form lived to reproduce and in reproducing took on the characteristics of its last inhabitant and its new host. Thus the alien on board the Nostromo had the characteristics of the space jockey on the derelict and Kane. If the facehugger had hit the cat, it could have been a hybrid of the space jockey and the cat. When Ripley blasts off from the Nostromo with the alien aboard, it's dying which is why it moves so slowly. She kills it, but it would have died soon anyway. It's like a butterfly (Fantastic Films #12, "Alien from the inside out", An exclusive interview with the Director of Alien, Ridley Scott, part two by James Delson p30)
  2. Ridley Scott: A way of explaining what had happened on the derelict [spaceship] and what was now happening on the NOSTROMO. And I think it provided some explanation for the Alien's killing spree -- like a butterfly or an insect, it has a limited lifespan in which to reproduce itself.  It also helped explain why it didn't attack Ripley in the Narcissus.  It's days were over.  Like a chameleon, it had found a protective corner in that ship and was working itself in there to die. ("Creating an Alien Ambience", Alien : The Special Effects)
  3. Ridley Scott: I want to show that the Alien has a limited life cycle, like a butterfly.  And within that period of time once it decides to expose itself - to coin a phrase - once it jumps out of the egg, it has to reproduce and spread fast as possible, maybe in a cycle of only days.  And so in the last sequence, you see slime emanating from the big Alien's body because we're trying to convey that maybe he's sealing himself in again, like a cocoon.  Also, by that point, he has to be provoked to attack, because he has to get on with his life cycle. (Book of Alien, by Scanlon and Gross)
  4. Ridley Scott: So whatever it impregnated, it could have been a dog and you would have had a dog version of alien. Impregnated with a man you get a man version of Alien. Which therefore maybe is even more lethal particularly if you’re picking up on man’s brain capacity as well. Because we never could work out…Gordon Carrol and I talked about this many times, you know, should we indicate the alien has intelligence. Or great intelligence. Or is it just a time bomb, just a time bomb, is it just a war machine? You know,…are those eggs simply war machines or are they ways of…another form of society adjusting itself like ants really…ants have…I think ants have no sense of beginning or end. They just are born, run around doing this thing like everybody else in the community and die. And I think that may have been the alien. So maybe the alien had no intelligence except pure intuition about survival. Right?  ( report from the interview with Ridley Scott carried out for the Alien Evolution documentary, 2001)
  5. Ridley Scott:  Je voulais que l'extra-terrestre change continuellement de forme. Quand il apparaît dans les machines vers la fin, il pourrait très bien être en train de mourir, terminant là son  cycle de vie très limité, peut-être même se métamorphosant en chrysalide de telle sorte que son volume physique diminue afin qu'il puisse revenir sous forme d'un œuf et hiberner à nouveau. Translation: I wanted that the alien continually changes shape. When it appears in the machines at the end, it could very well be dying, finishing there its very limited life cycle, maybe even metamorphosing into a chrysalis so that its physical volume decreases so that it could return in the form of an egg and hibernate again. (L'Ecran fantastique # 11, p12)
  6. Ridley Scott: Je voulais qu’Alien possédât au plus haut point cette force sexuelle. A un moment, dans le film, il apparaît si mince, si élégant, qu’il en devient presque trop humain. Mais, c’est normal; si la substance de l’œuf s’était répandue sur un chien, Alien aurait ressemblé à un chien. Dans le cas présent,  sa “mère“, c’est bien le personnage joué par John Hurt, il est donc logique qu’il ressemble à un homme. Translation: I wanted that ALIEN possessed the highest point this sexual force. At one point in the film , it seems so slim, so elegant, that it becomes almost too human. But this is normal ; if the substance of the egg had spread on a dog , Alien would have looked like a dog. In this case , his "mother" , it is the character played by John Hurt, so it makes sense that he looks like a man (Telerama n1548 12 septembre 1979)
  7. Ridley Scott: The thing that came out of the egg,  - the "perambulatory penis", as we used to call it - is the father. It is an abstact entity, in a sense, because all it does is plant a seed. Once having conceived, it dies and the next generation takes on characteristics of whatever life form it landed on. It could have been a dog, in which case, the Alien would have taken on a dog form. The result is a combination of two elements, the original creature and whatever host it uses. (American Cinematographer, August 1979, p842)
