Trivia: Arnie only has 16 lines.
Trivia: The skulls seen in the future segments were actually used as part of a technique to make the model set (and all the HKs on it) look bigger than it actually was. Fantasy II littered the set with little skulls that were about 3/4 of a inch in size and then placed a normal sized skull in the foreground for some shots. This created an illusion known as 'forced depth perception' which makes you continually think the scale of the picture you're seeing is larger than reality. An inexpensive but very effective trick.
Trivia: Before the Terminator drives up to the house of the first Sarah Connor, there is a shot of the house from the street. In this shot, you can see a small toy truck which looks exactly like the one the Terminator uses at the end of the film. In the next scene, you can see how the truck is run over and crushed by the car that pulls up. A small hint of what might happen in the future of the film. That model truck is one of those what the filmmakers made for filming the truck-blows-up scene.
Trivia: The final image of the Terminator in the film - where its red eye winks out after it had been crushed in the press - was actually one of the cheapest and simplest shots to create. It was done after principal photography had wrapped, when Cameron decided they needed the final shot. The press was made of foam core spray-painted silver, the eye was taken from one of the endoskeleton models and fitted with a small LED that was dialed down, the ring of metal that falls off was made of tinfoil, and the smoke wafting across was cigarette smoke blown on-camera by somebody out of the camera's field of view. Simple - but one of the most powerful images in the film.
Trivia: Michael Biehn gave a very impressive reading for the part of Reese, but Cameron didn't like the fact that he had such a prominent Southern accent. He called Biehn's agent and said that they loved the reading, but didn't want Reese to have a pronounced accent like that. The agent was confused: "What accent? He doesn't have an accent." It then transpired that Biehn had in fact just come from an audition for "Cat on a Hot Tin Roof" that morning, and hadn't shaken off the accent yet. So they had him come in for another reading, verified the lack of accent, and offered him the part.
Trivia: The "smoke" effect coming off Terminator's jacket during the scene where he is riding on the hood of Reese and Sarah's car in the alleyway outside Tech Noir was created by pouring a mild acid onto the jacket. Arnold begged for an alternative method, as the idea understandably made him rather nervous, but eventually he agreed to it.
Trivia: The Tunnel that Reese & Sarah throw pipe bombs at the Terminator is called The Second St. Tunnel between Hill & Figueroa St. in downtown Los Angeles. (01:24:15)
Trivia: If you watch the flying HKs you may notice the turbine pods on the sides look a little 'flat' at times. This is because Fantasy II had to start shooting the future war segments before they finished the small scale models so they built the body of the HK and then stuck cardboard on the sides so they could get the passing shots done. Then they added the engines.
Trivia: Reese arrives in a Alley on 7th & Broadway in downtown Los Angeles. This is also the same block they filmed the Tech Noir nightclub. (00:06:10)
Trivia: After the Tech Noir shootout, the Terminator takes out a hapless policeman (One-L-nineteen) and steals his car (and later impersonates his voice). This cop is played by Bill Wisher, a friend of Cameron's and co-writer of the script. Wisher also appears in "Terminator 2" as the shocked mallgoer with the camera, after the T-1000 throws the Terminator through the wall.
Trivia: The Tiki Motel is at 7301 Santa Fe Ave. in Huntington Park, CA. This is where Sarah & Reese make pipe bombs. (01:14:15)
Trivia: The "Tech Noir" shooting was done in a building in LA that used to be a restaurant. The set was so realistic that the night after shooting wrapped, people were trying to pay to get into the "club". Producer Gale Anne Hurd recalls that "we were so desperate for cash at that point that we almost took their money, but better sense got hold of us and we declined the paying patrons."
Trivia: The scenes in the restaurant that Sarah works at was filmed at Carrows Restaurant located at 815 Fremont Ave. South Pasadena, CA. (00:11:30)
