Director James Cameron got the idea for Terminator after having a vivid, intense nightmare in which he saw an episode of The Outer Limits with the same storyline
Michael Biehn is obsessed with time travel, and actually tried to create a time travelling machine seen in the film. He was found, naked and disoriented, 17 miles from his home in a pool of Jacob's cream crackers. This was worked into the storyline.
The film was the first to be shot entirely in reverse.
For most of the filming, Arnold Schwarzenegger believed he was making a comedy and wanted to wear a curly ginger wig. James Cameron put him off the idea by shouting at him very loudly.
This was not Michael Biehn's last film.
Ha ha ha! Look at their haircuts!
Throughout the film, a major theme is the dangers of technology. Watch out for a deleted scene where Kyle Reese gets his hand stuck in a toaster and trips over a George Foreman grill.
This is Morrissey's favourite film of all time
The Terminator cannot be stopped, cannot be bargained with, and absolutely will not stop until you are dead. But did you know that his favourite colour is pink?
Ha ha ha! Look at the size of her Walkman!
An earlier version of the script eliminates Arnold Schwarzenegger's character and is an interesting look at mental illness and stalkers.
