Alien (film) - Set Design and Filming

Set Design and Filming

Alien was filmed over fourteen weeks from July 5 to October 21, 1978. Principal photography took place at Shepperton Studios in London, while model and miniature filming was done at Bray Studios in Water Oakley. Production time was short due to the film's low budget and pressure from 20th Century Fox to finish on schedule. A crew of over 200 workmen and technicians constructed the three principal sets: The surface of the alien planetoid and the interiors of the Nostromo and derelict spacecraft. Art Director Les Dilley created 1/24th scale miniatures of the planetoid's surface and derelict spacecraft based on Giger's designs, then made moulds and casts and scaled them up as diagrams for the wood and fiberglass forms of the sets. Tons of sand, plaster, fiberglass, rock, and gravel were shipped into the studio to sculpt a desert landscape for the planetoid's surface, which the actors would walk across wearing space suit costumes. The suits themselves were thick, bulky, and lined with nylon, had no cooling systems and, initially, no venting for their exhaled carbon dioxide to escape. Combined with a heat wave, these conditions nearly caused the actors to pass out and nurses had to be kept on-hand with oxygen tanks to help keep them going. For scenes showing the exterior of the Nostromo a 58-foot (18 m) landing leg was constructed to give a sense of the ship's size. Ridley Scott still did not think that it looked large enough, so he had his two sons and the son of one of the cameramen stand in for the regular actors, wearing smaller space suits to make the set pieces seem larger. The same technique was used for the scene in which the crew members encounter the dead alien creature in the derelict spacecraft. The children nearly collapsed due to the heat of the suits, and eventually oxygen systems were added to assist the actors in breathing.

The sets of the Nostromo's three decks were each created almost entirely in one piece, with each deck occupying a separate stage and the various rooms connected via corridors. To move around the sets the actors had to navigate through the hallways of the ship, adding to the film's sense of claustrophobia and realism. The sets used large transistors and low-resolution computer screens to give the ship a "used", industrial look and make it appear as though it was constructed of "retrofitted old technology". Ron Cobb created industrial-style symbols and color-coded signs for various areas and aspects of the ship. The company that owns the Nostromo is not named in the film, and is referred to by the characters as "the company". However, the name and logo of "Weylan-Yutani" appears on several set pieces and props such as computer monitors and beer cans. Cobb created the name to imply a business alliance between Britain and Japan, deriving "Weylan" from the British Leyland Motor Corporation and "Yutani" from the name of his Japanese neighbor. The 1986 sequel Aliens named the company as "Weyland-Yutani", and it has remained a central aspect of the film franchise.

Art Director Roger Christian used scrap metal and parts to create set pieces and props to save money, a technique he employed while working on Star Wars. Some of the Nostromo's corridors were created from portions of scrapped bomber aircraft, and a mirror was used to create the illusion of longer corridors in the below-deck area. Special effects supervisors Brian Johnson and Nick Allder made many of the set pieces and props function, including moving chairs, computer monitors, motion trackers, and flamethrowers. Four identical cats were used to portray Jones, the Nostromo crew's pet. During filming Sigourney Weaver discovered that she was allergic to the combination of cat hair and the glycerin placed on the actors' skin to make them appear sweaty. By removing the glycerin she was able to continue working with the cats.

H. R. Giger designed and worked on all of the alien aspects of the film, which he designed to appear organic and biomechanical in contrast to the industrial look of the Nostromo and its human elements. For the interior of the derelict spacecraft and egg chamber he used dried bones together with plaster to sculpt much of the scenery and elements. Veronica Cartwright described Giger's sets as "so erotic...it's big vaginas and penises...the whole thing is like you're going inside of some sort of womb or whatever...it's sort of visceral". The set with the deceased alien creature, which the production team nicknamed the "space jockey", proved problematic as 20th Century Fox did not want to spend the money for such an expensive set that would only be used for one scene. Ridley Scott described the set as the cockpit or driving deck of the mysterious ship, and the production team was able to convince the studio that the scene was important to impress the audience and make them aware that this was not a B movie. To save money only one wall of the set was created, and the "space jockey" sat atop a disc that could be rotated to facilitate shots from different angles in relation to the actors. Giger airbrushed the entire set and the "space jockey" by hand.

The origin of the jockey creature was not explored in the film, but Scott later theorized that it might have been the ship's pilot, and that the ship might have been a weapons carrier capable of dropping Alien eggs onto a planet so that the Aliens could use the local lifeforms as hosts. In early versions of the script the eggs were to be located in a separate pyramid structure which would be found later by the Nostromo crew and would contain statues and hieroglyphs depicting the Alien reproductive cycle, offering a contrast of the human, Alien, and space jockey cultures. Cobb, Foss, and Giger each created concept artwork for these sequences, but they were eventually discarded due to budgetary concerns and the need to trim the length of the film. Instead the egg chamber was set inside the derelict ship and was filmed on the same set as the space jockey scene; the entire disc piece supporting the jockey and its chair were removed and the set was redressed to create the egg chamber. Light effects in the egg chamber were created by lasers borrowed from English rock band The Who. The band was testing the lasers for use in their stage show in the sound stage next door.

Alien originally was to conclude with the destruction of the Nostromo while Ripley escapes in the shuttle Narcissus. However, Ridley Scott conceived of a "fourth act" to the film in which the Alien appears on the shuttle and Ripley is forced to confront it. He pitched the idea to 20th Century Fox and negotiated an increase in the budget to film the scene over several extra days. Scott had wanted the Alien to bite off Ripley's head and then make the final log entry in her voice, but the producers vetoed this idea as they believed that the Alien had to die at the end of the film.
