evo malo trivie iz najpredrkanijeg dela :
All of the cast who were to play the Marines (with the exception of Michael Biehn, who replaced an actor one week into filming) were trained by the S.A.S. (Special Air Service, Britain's elite anti-terrorist force) for two weeks before filming. They were also instructed to read Robert A. Heinlein's novel "Starship Troopers". Sigourney Weaver, Paul Reiser, and William Hope didn't participate/attend the training because director James Cameron felt it would help the actors create a sense of detachment between the three and the Marines - the characters these three actors played were all outsiders to the squad; Ripley being an advisor to the Marines while on the trip to LV-426, Burke being there just for financial reasons and Gorman being a newly-promoted Lieutenant with less experience than most of the Marines.
Lance Henriksen wanted to wear double-pupil contact lenses for a scene where Bishop is working in the lab on a microscope and gives a scary look at one of the Marines. He came to set with those lenses, but James Cameron decided he did not need to wear them because he was acting the character with just the right amount of creepiness already.
The "special edition" includes extra scenes: Newt's parents discovering the abandoned alien ship on LV-426, scenes of Ripley discussing her daughter, Hudson bragging about his weaponry, robot sentry guns repelling first alien raid, and Hicks and Ripley exchanging first names. Also included is a scene on LV-426 where a child rides a low-slung tricycle similar to one ridden in The Terminator (1984), also directed by James Cameron.
The Alien nest set was kept intact after filming. It was later used as the Axis Chemicals set for Batman (1989). When the crew of Batman (1989) first entered the set, they found most of the Alien nest still intact.
Budget constraints meant that they could only afford to have six hypersleep capsules for the scenes set on board the Sulaco. Clever placement of mirrors and camera angles make it look like there's about 12. Each hypersleep chamber cost over $4,300 to build.
The assault vehicle is a modified tow-truck that British Airways used for towing airplanes around at Heathrow. The only trouble was that the truck they purchased weighed 75 tons. By stripping out most of the lead used in its construction, they were able to remove about 30 tons.
The pulse rifles that the Marines use are made from a Thompson M1A1 machine gun with a Franchi SPAS 12 shotgun underneath.
The M-56 smart guns and the sentry guns built for the movie were designed around German MG 42 machine guns.
Al Matthews, who plays a Marine sergeant in this film, was in real life the first black Marine to be promoted to the rank of sergeant in the field during service in Vietnam.
In both the standard and special edition versions, the fifteen minute countdown at the end of the film is indeed fifteen minutes.
Bishop states that "it is impossible for me to harm, or by omission of action allow to be harmed, a human being." This is based upon the First Law of Robotics written by science fiction author Isaac Asimov.
According to myth, the name for the company, "Weyland Yutani", was taken from the names of Ridley Scott's former neighbors - he hated them, so he decided to "dedicate" the name of the "evil company" to them. In reality the name was created by conceptual designer Ron Cobb (who created the Nostromo and the crew's uniforms) to imply a corner on the spacecraft market by an English-Japanese corporation. According to himself, he would have liked to use "Leyland-Toyota" but obviously could not so he changed one letter in Leyland and added the Japanese name of his (not Scott's) neighbor.
