Alien Explorations: Alien:Romulus - Alien beast coming out of the cocoon

Special effects man Shane Mahan and director Fede Alavarez on the Corbelan set witih the alien cocoon

a) Adding another stage to the life cycle

Fede and his team thought that they could add something to the alien life cycle without betraying what they deemed as canon, without contradicting anything that happens in the movies, particularly the third one.

He was thinking about the deleted scene fom Alien which had been introduced back into the story in the director's cut, where the viewer would see the alien nest with Brett and Dallas cocooned and the egg shell growing around Brett's remains. (See: Alien: Human To Spore)

He thought that there was more to it even if you accepted Ridley's nest scene or not. He decided tha there was more happening in the ship than the viewer would know about and he thought that was acceptable.

There would be the shock level as this things growls and then it starts to be born from the cocoon with the arms opening.

b) Shane Mahan's point of view

Shane Mahan and his team would execute the scene in a way that Fede thought was flawless, although in the final movie, it's only barely seen

Mahan looked at how in this birthing sequence, there was a hand with the fingers seemingly bent backwards and then they unfold

He thought it was an important moment for that sequence because it was like a butterfly coming out of a cocoon, when it doesn't really have joints or bones, but it's something interesting to look at, and it helped by his understand to tell the storu of how it was emerging or coming alive

c) Fede's explanation behind the biomechanics

The cocoon was near enough blended with the ship, so that the viewer would see the pipes from the ship entering the cocoon as if hey were turning into organic matter.

For whatever reason, Fede thought this justified the biomechanical aspects of the creature as if it were amalgamated the mechanics of the ship into its DNA.

Fede thought that the new generation of audience who hadn't seen tthe films before would say "look at that, it's kind of born out of the mix of the ship and its own DNA"

Fede thought it was wonderful and it would definitely get a moment where the audience said "wow"

Fede Alvarez: We thought we could add something without betraying the canon, without contradicting anything that happens in the movies, particularly in the first one, particularily the deleted scene from the first one, you see the eggs on the walls, there's more to it even if you accept that or not, but I think there's more happening in the ship but we don't know about it, so I think that's acceptable. Anyhow that shock level as well, the growling, that's when it starts being born, the opening of the arm, all those things I think again, I think Shane and his team executed flawlessly but also, I don't think you get to see it clearly in the movie but the... the cocoon is kind of, is kind of blended with the ship so you see the tubes all sort of, they start running through the wall, they start turning into organic matter, they turn into cocoon, which for me give way to justify why this happened, all the biomechanical aspects of the creature because it almost it's taken the energy, if like in a way the DNA of the mechanics of the ship, amalgamation ... amalgamated way and that's why again, for a new generation, a new audience who haven't seen it, if they see that grow and it's got spikes on the side of its head they say look at that, it's kind of born out of the mix of the ship in its own DNA, and so I thought that was cool and that would definitely get it a good wow moment, and I think obviously the first one has (Perfect Organism: Interviewing Fede Alvarez Part 2, September 2024 (NB I'm still trying to decipher what Fede is saying word for word, but I think I've got the basic sense of his statements transcribed at least)
When asked to name a moment where such an instance occurred, Mahan refers to the close-up of the elongated Xenomorph fingers piercing through the embryonic sac during the Cocoon effect: “In the [Xenomorph] birthing sequence, there’s a hand that the fingers kind of bend backwards and unfold on themselves. That was an important moment for that sequence because it’s like a butterfly coming out of a cocoon, where it doesn’t really have joints or bones, but it’s something interesting to look at, and it helps tell the story of how it is emerging or coming alive.” Adds Mahan, “And we certainly had to get the attack heads, where the tongue is going and attacking into the head of a character. Just getting that timing to make sure that we get that shot correct. It’s a gruesome shot, but it’s an iconic element of the Alien franchise. Someone’s going to get the secondary mouth shot through the eye."(https://www.laweekly.com/building-nightmares-shane-mahan-gives-a-behind-the-scenes-dive-into-the-special-effects-of-alien-romulus/)

d.xiv) Sculpture of the cocoon

Dane Hallett: Partly spooked by the talent already on board Romulus, and my admiration for Fede, I was choking on the cocoon shape, trying to get it just right.

After many drawings, I sculpted one out of frustration, photographed it, then painted over it.

Here is that rough sculpt and then the photos of the final one on set taken by Fede a few months later.

Did I say I loved this job, already!? (Instagram, 3rd September 2024)
