Opening

The derelict in the storm. As a kid my question wasn't "what is the monster?", it was "what is inside that ship, and who made it?"

This deck is the answer I've been assembling since: the painters, sculptors, model makers, set dressers and the director who put them together.

How did anyone make this?

Alien, 1979. Directed by Ridley Scott.

Five sets, all built by hand at Shepperton Studios.

The question

Five worlds, all physical: the jockey chamber, the egg chamber, the Nostromo's decks, the planetoid surface and the derelict. Nothing here is a digital effect. We'll take them apart one by one.

As a kid I thought the answer was a monster. It turned out to be designers.

200+workmen and technicians built the three main sets

I design for a living now. This is the film I keep taking apart.

The team

A crew of over 200 workmen and technicians built the three principal sets: the planetoid surface, and the interiors of the Nostromo and the derelict. Filming ran fourteen weeks, from 5 July to 21 October 1978.

Scott's hand: shooting started before many of the sets were finished, so he framed his shots around the unfinished sections.

The dot count covers the set builders alone; the full credited crew, from effects to accounts, was larger still.

Ridley Scott

He drew the film first

Seven years of art school before his first feature. For Alien he storyboarded the script himself, shot by shot.

$4.2m$4.2m

Fox's budget. After seeing the boards, the studio doubled it.

Frames from the finished film, laid out as a shot list.

The Ridleygrams

Fox planned to finance the film at $4.2 million. Scott's detailed storyboards, known as "Ridleygrams", convinced the studio and it went to $8.4 million.

Scott has said art school was the most valuable thing he ever did. Roger Christian remembered arriving to find Scott's office walled with Giger paintings and Ridleygrams.

These panels are frames from the film itself, not his drawings. If I can get scans of the real boards, they'd sit perfectly here side by side with the frames.

Two worlds, two design languages

H. R. Giger. Biomechanical. Bone, resin, tubes: something grown rather than built.

Two design languages

Cobb and Foss handled the human side (the Nostromo and its equipment); Giger owned everything alien. The two teams were reportedly kept apart so neither vocabulary would bleed into the other.

The film's tension is partly a design collision: an oily, practical truck gets invaded by something that looks organic and ancient.

The Nostromo, outside

A space truck, not a starship

Ron Cobb designed from function towards form. Hulls of wood and plastic, detail kit-bashed from battleship, tank and WWII bomber model kits, windows lit by hundreds of feet of fibre optics.

From sketch to model

Foss worked form-first, Cobb function-first, and their processes never quite meshed. The producers couldn't settle on a design, so Johnson grabbed the concept art off the art department wall and made the call himself.

The scale drawing is to true proportion: the hero model was almost twice as long as a person is tall.

The model was first built and shot yellow, straight from Cobb's drawing. When Scott arrived at Bray he found it garish and ordered it grey; standard grey primer looked flat, so it went out in zinc plate primer, which polished up like metal.

You could walk from the bridge to the mess

Production designer Michael Seymour built the ship as connected sets across three stages at Shepperton, so actors, and the audience, felt trapped inside one real vessel.

CEngine room, equipment corridors, the claw room
Scott's handOnce it was built, he had them lower the ceiling.

A real place

Seymour wanted it to read as science fact, "well used, lived in and slightly battered". The bridge alone had around forty screens, fed from a video centre built out of old aircraft, cars, radios and TVs.

American Cinematographer described an intersecting lobby with two large perspex-fronted wardrobe cases holding spare suits and helmets, which is what this photo shows. I'm not certain whether it's the 1978 set or a later recreation, so I've left the date off.

Roger Christian, art direction

Scrap sold by weight, and aircraft are light. His team bought it up around England, broke it down and fitted every piece as if it had a function. Then everything was painted army green and aged with oil, drips and small graphic symbols.

Dressing with purpose

Christian had developed the scrap-dressing technique on Star Wars. His point was that it can't be random: in a real aircraft or submarine, everything is in order and has a job, so he trained the prop crew to place it that way.

Scott said Christian's "cladding" made everything look absolutely real.

Ron Cobb's Semiotic Standard sheet: 21 symbols in red-framed tiles, with a colour key along the bottom
Ron Cobb's Semiotic Standard sheet. Every symbol sits on the same grid, and the strip along the bottom is the colour key.

Signage for a ship that never flew

Cobb drew a full pictogram system for the Nostromo: colour-coded by category, built on a grid, readable at a glance. Designers still point to it as an ancestor of app icons and emoji.

A system, not a set of pictures

Cobb's full title for it: the Semiotic Standard for All Commercial Trans-Stellar Utility Lifter and Heavy Element Transport Spacecraft. The sheet codes each category by colour, with a key along the bottom: red, white, grey, black, yellow, blue and green.

The icons appear throughout the sets, including on Ripley's keyboard. The Iconfactory compared them to iOS 7's system icons; Typeset in the Future catalogued them in detail. His originals are collected in his book Colorvision.

The team

System Simulation (Syssim) was one of Britain's pioneering computer animation studios. John Lansdown, who ran the Computer Arts Society from Syssim's Russell Square offices, was part of its story; George Mallen ran the Alien job.

This is the real Deorbital Descent screen, the one the crew watch as the Nostromo drops towards the planetoid.

The screens that set the standard

In 1979 computer graphics in films were a few years old and rare. Many screens were still hand-drawn animation or backlit slides. Alien's were real computer output, plotted frame by frame and played on the set.

Since then its vocabulary has been copied everywhere: vector lines on black, boxed data rails, capital-letter labels, one phosphor colour. The look even has a name now, cassette futurism.

Why they mattered

Before Alien, computer imagery in features was a handful of moments: Westworld's pixelated robot's-eye view, Futureworld's 3D hand and face, Star Wars' short wireframe trench briefing. Alien filled a whole set with working graphics, from System Simulation's vector plots to the Atlas lab's raster wireframe landing terrain, in a film that won the Oscar for Visual Effects.

Sci-fi Interfaces points out that the flight-path display in Aliens (1986) bears an uncanny resemblance to Ash's dropship interface here. Alien: Isolation built its whole game around the 1970s vision of the future, and Romulus and Alien: Earth went back to the same grimy analogue tech rather than the sleek look of the prequels.

"Set the standard" is my framing: what's documented is how often later work goes back to it.

How a screen got onto the set

The graphics were plotted onto film first, then fed into the bridge monitors from a video centre, so the actors were looking at real screens.

The pipeline

They went to the Atlas lab because it had an FR80, a very high-resolution vector film plotter that output 35mm film. Emmett, an artist, had worked on the ANTICS animation package there with Alan Kitching. The sequences were late, and Wyvill spent his time debugging Emmett's FROLIC code and adding features.

Wyvill was paid seven pounds an hour, and Scott kept them waiting three or four hours before viewing the rushes.

The animated terrain on this slide is my own homage, not footage.

Two interface languages

The film splits its UI in two: pictures for piloting, text for the computer. Mother never has a face or a voice until the end; she's all type on a screen, which is part of why she feels cold.

The suits were so heavy and airless under 100°F studio lights that actors passed out. Oxygen was kept on standby.

Moebius (Jean Giraud) was one of the first two concept artists hired, with Chris Foss. John Hurt, Tom Skerritt and Veronica Cartwright wore the bulkiest suits.

Necronom IV by H. R. Giger

H. R. Giger's imagination

Dan O'Bannon put Giger's book in front of Scott. On one page, the creature already existed.

Necronom IV, 1976

The starting point

O'Bannon had met Giger on Jodorowsky's abandoned Dune and remembered him. Scott travelled to Zurich to meet Giger in February 1978.

Wikipedia, Xenomorph; AvP Galaxy.

“One brain on all the Alien stuff.”

Ridley Scott

Giger proved so reliable that Scott handed him the landscape too. He designed the planet, the derelict inside and out, the Space Jockey, the egg chamber and every stage of the creature.

One author for the alien

Scott's instinct was to keep a single sensibility across everything alien, so the planet, ship, pilot and creature all feel like parts of the same biology. Giger then worked at Shepperton with his own hands, often in a boiler-room workshop.

The Derelict

A crashed alien ship, found on the planetoid the sequels call LV-426. The film never names it: the crew just call it the derelict.

  • SkinNetting, then plasticine, fitted with cables and technical parts
  • DetailingPeter Voysey, straight from Giger's plasticine models

Naming the craft

In the 1979 film the ship is only ever "the derelict". Later films and expanded lore link it to the Engineers' ships, sometimes called Juggernauts.

Giger takes over

Giger felt the first builders didn't understand his architecture. He told them to get bones and work in plasticine, and ended up doing much of it himself. In stills there's far more detail on the derelict than you can see on screen.

Building the planetoid

The custom styrofoam tubes first came out with ribs far too big; Giger had to climb over the "bone mountain" inserting them by hand. Brian Muir, who had sculpted Darth Vader's helmet, joined Peter Voysey on the derelict entrances. Sand, fibreglass and rocks were shipped in for the ground, and a 45-foot Nostromo landing leg was built on the set for scale.

Alien Explorations, "Derelict entrance"; Screen Rant; Dark Visions; Alien Anthology Wiki.

Fox said no. Scott built one wall.

A huge set for a single scene was too expensive. Scott refused to cut it. One wall was built, Giger airbrushed it by hand, and the pilot sat on a turntable so it could turn between shots.

Scott's handStill not big enough. For the wide shots he put his two sons and Derek Vanlint's son in child-size spacesuits.

Approximate, to scale

The pilot

Giger and Voysey first modelled the pilot in plasticine at 1/25 scale, in a hut in the Shepperton car park, on 25 July 1978. Scott wanted it fused into its chair at the centre of the chamber's curve.

Ron Cobb argued for keeping it, calling it the film's "Cecil B. DeMille shot": the moment that stops it looking like a B-movie.

Giger working on the eggs

An egg, designed twice

Giger's first egg was so anatomical the room burst out laughing. Art director Les Dilley suggested it open like a flower, so Giger doubled the slit to four lobes.

Seen from above: a cross.

First pass Final, four lobes

The redesign

Producers worried Catholic countries might ban the film if the allusion was too strong. Giger's own joke was that from above the four lobes form the cross "people in Catholic countries are so fond of looking at". Others read it as a heart valve.

Giger called the eggs "organic footballs".

  6. The strikeA sheep's intestine on an air line
An egg's lobes peeling openGIF

Scott inside the egg

The close-up of Kane at the egg was shot later. Scott himself provided the movement you see through the shell, and rigged the facehugger's strike by putting an intestine on an air line; he said it came out like a whip.

Counts vary: some sources say 100 eggs were made, others 130, with only a few carrying the extra detail.

Light as set design

Smoke, backlight and a single sheet of blue light turned a redressed set into a place you can't map. For me this is where cinematography becomes part of the set design.

The facehugger clamped onto KaneGIF

Each stage needed its own maker

Giger designed the whole life cycle. Roger Dicken built the facehugger and the chestburster.

The facehugger

Giger's early facehugger designs were abandoned on his workbench in the Shepperton boiler room before the final version was built.

1 take

Once it burst, the white set would take about two weeks to clean. The cast weren't told exactly what would happen.

Scott's handOn the first try only a bump flashed under the shirt. He cleared the set, crawled onto the table and razor-bladed John Hurt's T-shirt so it would tear. The second attempt was perfect.

The chestburster

Giger's first chestburster looked, Scott recalled, like a turkey on his arm. Roger Dicken built the final creature from his designs; Francis Bacon's 1944 Three Studies for Figures at the Base of a Crucifixion was a reference. Hurt sat in a deckchair under a false torso with only his head and arms through.

The performer

Giger sculpted the final adult form in plasticine. Badejo's slow, deliberate movement is what makes the suit read as a living thing.

Carlo Rambaldi, mechanical head

About four minutes

Jaw, inner mouth, cables, hundreds of moving parts. And the creature is on screen for roughly four minutes. Scott built something extraordinary, then kept it in the dark.

Restraint

Rambaldi adapted Giger's design to take the mechanisms for the jaw and inner mouth; one source puts the head at around 900 moving parts. Scott deliberately never shows the creature in full until the end.

Behind the scenes, part 1

From brief to body

It started with a typed list. Dan O'Bannon's letter told Giger what to design, from leathery spore pods to a creature in three phases, and ended by inviting him to “feel free to create your own design”.

Photographed from the book Giger's Alien. Select any image to see it larger.

From brief to body

O'Bannon's letter to Giger listed an ancient temple, spore pods about a metre tall, and the creature's three phases. It mentions that the producers had suggested something like an oversized, deformed baby, then leaves the design to Giger.

From there: paintings, then moulds and castings in the workshop, Rambaldi's mechanics for the head, and Giger painting the eggs himself.

Photographed from Giger's Alien (H. R. Giger).

Behind the scenes, part 2

Painted, modelled, built

Every alien space went the same way: a Giger painting, a scale model, then the full-size set in timber, plaster and scaffolding. The egg silo got as far as a 1/25 model before it was cut, and its eggs moved into the derelict.

Photographed from the book Giger's Alien. Select any image to see it larger.

Painted, modelled, built

The Space Jockey went from Giger's painting to a full-size sculpture. The egg silo, a separate pyramid where the eggs were meant to be found, was painted and built as a 1/25 model, then cut from the film; the eggs were moved into the derelict instead.

My reading of Giger's handwritten German note on the pyramid sketch: it mentions an egg carton, and that the pyramid between the eggs gives the form. The photo beside it is that egg-carton study.

The wreck entrance was framed in timber and scaffolding, then skinned and sculpted until it read as grown rather than built.

Sampled from the frames

Five palettes pulled from the film. Almost everything lives in the bottom third of the value scale, and colour only arrives as light.

A designer's aside

I sampled these by quantising single frames to their dominant colours. The human world runs cold blue-grey; the alien world is bone and ash; red only appears once the body is opened.

The creature's head in the dark, jaws slick and parted

End on the creature, in the dark, the way Scott would.
