Think you know everything about The Terminator? Here are some facts and interesting trivia, from how the idea was born to some of the smaller unknown bits of the show involving Arnold and more! Check it out:

1. The idea for the Terminator series came to James Cameron when he was in Rome during the release of his film 'Piranha II: The Spawning.' He fell ill and had a dream about "this metal death figure coming out of a fire..the implication was that it had been stripped of its skin by the fire and exposed for what it really was."

2. Cameron says that the final design for the T-800 is identical to the "death metal" figure he saw in his dream.


3. (What kind of nightmares does Cameron have?!)


4. Cameron had to sit on the idea for nine months before work began as Arnold was busy with "Conan The Destroyer." Cameron relaxed for that period and wrote a screenplay for a movie called "Aliens."


5. Arnold didn't want to play T-800 at first because it was the villain's role. But Cameron convinced him that the movie will be shot in such a way that made audiences would cheer the killing machine.


6. In Judgment Day, Arnold didn't like that the T-800 would now be the good guy. So he convinced James Cameron that the character would only stop killing when John Connor told him not to.


7. Arnold and James disagreed on the former's iconic catchphrase, "I'll be back." Arnold wanted to say "I will be back" because he thought it sounded more machine-like. Cameron said: "I don't tell you how to act, so don't tell me how to write."


8. Arnold's $15 million salary was for a total of 700 words of dialog. Making it $21,429 per word.


9. Terminator was renamed "The Electronic Murderer" in Poland because Terminator in Polish means "an apprentice."

11. The Terminator had hardly any special effects. Most of it was created and shot in-camera, while others used miniature sets.


12. Cameron shot most of the scenes of "The Terminator" at night with the street that had mercury-vapour lamps to help keep the cost of filming low, giving it a neo-noir look.


13. Industrial Light and Magic's computer graphics department had to grow from six artists to almost 36 to accommodate all the work required to bring the T-1000 to life. It took $5.5 million and 8 months to produce for a total 3.5 minutes of screen time.


14.  The Terminators seen at the beginning of the movie were fully workable animatronic models.


15. Linda Hamilton's twin sister Leslie doubled for her when the T-1000 acquires Sarah Connor's form.


16. Edward Furlong was only 13 years of age at the time of filming. He had to rerecord a substantial amount of dialogue due to the sudden voice change.
