Trivia: The insert car driver (towing the bike ridden by Eddie Furlong) was warned at the very beginning of the scene where John rides out of the mall and the T-1000 is chasing him, that Robert Patrick could run exceptionally well. The driver confidently said that Patrick wouldn't catch him. However, on the very first take, Patrick ran right up and tapped Furlong on the shoulder. So if this was real life, the human race would be in trouble.
Trivia: Makeup artist Jeff Dawn has said that in order to give the Terminator (Arnold Schwarznegger) a look that set him apart from the other "human" actors, the makeup artists "mixed in a little bit of K-Y Jelly into the straight make-up, to give him that 'I'm different-looking but you don't know why' look...It's a sort of plastic-man appearance."
Trivia: So that he didn't have to use a split screen, director James Cameron hired twins to play the security guard and his T-1000 double at the hospital. Linda Hamilton's twin sister Leslie Hamilton Gearren was used in the scene where the T-1000 is disguised as Sarah, although as the focus is on the T-1000, in those shots Linda Hamilton plays the robot with her sister playing Sarah.
Trivia: The police computer which the T-1000 uses to locate John Connor's juvenile delinquent record was a functional mobile data terminal on loan from ElectroCom Automation. The prop was the subject of many crew members' inquiries of "Hey, can you look up my record for any outstanding warrants?" They were disappointed when they found out it was not hooked into any actual police databases, but had been programmed to simply display John's record.
Trivia: Jim Cameron once quoted "You can do anything to a terminator, but don't break his sunglasses, that really pisses them off."
Trivia: The film cleverly mirrors the original on many occasions, many of them are featured here but one of the more subtle ones is the way Arnie gets up after being thrown through the window in the mall. It is shot the same way and he moves the same way as when he is on the ground outside the Tech Noir Club in T1.
Trivia: Actors Robert Patrick (T-1000) and Joe Morton (Miles Dyson) would reunite more than 10 years later on Fox's 'The X-Files'. The plot of the episode is eerily similar to that of the Terminator: Joe Morton's character is given a second chance, going back in time one day at a time to stop a murderer from killing his wife, trying to clear his own name in the process. Very interesting similarity in themes.
Trivia: After the T-1000 throws the Terminator through the window in the mall, a shocked man is seen shooting photos with his camera. This man is Bill Wisher, a friend of Cameron's and co-writer of the script. Wisher also appears in "The Terminator" - he's the cop whose car the Terminator takes after the Tech Noir shootout ("One-L-nineteen"). (00:31:50)
Trivia: Early in the movie after the chase, between Arnie and John (riding a bike) and T-1000 (in the truck), the truck explodes. Arnold then aims his Winchester, waiting for the T-1000, but he does not come out of the fire and Arnold puts the gun down without looking. The Winchester passes so closely from John's head that you can see it brush his hair. In another take, he actually got hit by Arnie - he's said so in interviews. (00:36:40)
