Arnold only has 16 lines.

At the beginning of the film, Sarah listens to an answering machine recording of her boyfriend breaking up a date. The voice heard on the answering machine belongs to James Cameron.

The classic line, "I'll be back." was originally scripted as "I'll come back."

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.

The body bag that Reese is zipped up into at the end of the film is actually a suit bag that belonged to director James Cameron. They needed a pickup shot and Cameron happened to have the bag in his car, so he pulled it out and presto, instant body bag.

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.

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.

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.

A "steel fist" machine rig was used to punch through the windshield of the car in the alleyway scene. The rig was so heavy that the car couldn't be moved, so instead they moved the brick wall behind the car to give the appearance that the vehicle was in motion.

The Tiki Motel is at 7301 Santa Fe Ave. in Huntington Park, CA. This is where Sarah & Reese make pipe bombs.

Lance Henriksen was originally considered for the role of the Terminator but was dropped in favour of Arnold and instead cast as Vukovich. Henkriksen would however later go on to be cast as the android Bishop in 'Aliens'.

The department of Water & Power was used as the parking garage located at 111 N. Hope St. in downtown Los Angeles.

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.

James Cameron originally wanted Lance Henriksen as the Terminator, and Henriksen really got into the idea of playing the character. Cameron scheduled a meeting with executive producer John Daly to show how great Henriksen would be as the Terminator. Unfortunately Henriksen showed up early - in full makeup, with bits of metal exposed and utterly in character - and frightened the hell out of everyone in the building before Cameron arrived and was able to reassure everyone.

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."

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.

The start of shooting was delayed for two days because The Terminator's custom leather jacket didn't fit him correctly.

The Alamo Gun Shop is located at 14329 Victory Blvd. Van Nuys, CA. It is now a used Car lot. Across the street is also where the Terminator throws the Biker from the phone booth.

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.

The name of the nightclub, "Tech Noir", was a deliberate allusion to "film noir" - director James Cameron hoped that critics might be interested in the kind of filmmaking they were doing with this film, the references to the dark side of technology.
