causing one actress to pass out and another actor to nearly have a heart attack after having a few gallons of animal parts exploded onto their bodies.
Alien was filmed over fourteen weeks from July 5 to October 21, 1978. Principal photography took place at Shepperton Studios near London, while model and miniature filming was done at Bray Studios in Water Oakley, Berkshire. 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. 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
