Corrected entry: When the tow truck finally crashes and the battery lead ignites the fuel, this would not happen as surely the truck is diesel powered, and diesel does not ignite in that way. (00:36:20)
Corrected entry: After the Terminator tells Dyson what his work will eventually do, Dyson speaks several lines of dialogue. If you pay close attention to Sarah during this scene, you will see her mouthing his lines. (01:27:30)
Correction: She is repeating what she has heard a million times, in the last film. She is pointing out Dyson's guilt in a very telling and sarcastic manner.
Corrected entry: T-800's metal finger shouldn't be so big when he touches Connor's tears (it's almost as big as his gloves). We can see it's much thinner when he cuts off his skin at Cyberdyne's house.
Correction: The T-800 reveals his metal arm to Dyson but we then see he puts a glove on that hand and his jacket covering the rest of the arm for the remainder of the film. So whether he left the skin off his arm is impossible to tell. Being that his hand fills the glove we can presume he did put the skin back on his arm.
Corrected entry: When Sarah takes the broken broomstick and hits the psycho-ward guard in the face, you see a large amount of blood come out of his mouth and spray back. When she starts dragging him into the empty cell, there is no blood on the floor.
Correction: The blood only shows up as a reflective streak on the floor, because of the angle of the light, and the colour isn't obvious, but there is definitely blood on the floor as she starts to drag him away. The floor seems pretty clean when she comes out again, but the blood could have been wiped away as she dragged the body over it.
Corrected entry: Why didn't the machines send the T-1000 back in time to 1984 to help the first Terminator? Even if the rebels had sent the reprogrammed T-800 back to 1984 as well that would have confused the hell out of Reese and Sarah, which would surely only have helped.
Correction: For that matter, why the machines didn't send the T-1000 to kill Sarah Connor when she was a kid - and, thus, an easier target? Or why didn't they send the T-1000 to kill John Connor when he was 9, instead of 10 years old? That was an arbitrary choice of the script, and any year would give space to questioning. So, why bother? The real reason was: the movie was made in 1991 and so Cameron decide to set the story in 1991.
The story is set in 1994.
Corrected entry: In the scene where Arnie and John Connor are underneath the pickup truck, doing some repairs, just before the terminator asks "Why do you cry?", Arnie is tightening something with a wrench and lets out a very audible grunt. My impression was that a killer robot like him wouldn't have problems with strain. (01:24:00)
Correction: Arnie is an infiltration unit designed to appear human. Since a human would strain Arnie would simulate having to strain to tighten the bolt so as not to blow his cover.
Corrected entry: In the scene where John and Arnie are talking on the phone to the T-1000, who has killed and is imitating John's foster mother, Todd gets a drink from a carton and complains about the dog barking, the T-1000 stabs him through the carton, mouth and out of the back of his head pinning him upright against the kitchen wall killing him instantly, yet for over 30 seconds he is still gripping the carton with his left hand. (00:41:30)
Correction: When people die, the muscles in their hands contract, making it possible for them to hold something for a while longer after they've died.
Corrected entry: In the scene when Arnold, Sarah and John escape the mental hospital, and the T-1000 is walking back down the street, he runs into a cop on a bike. When we see him talking, steam is coming out of his mouth like it is cold outside. But he is not human, so this is not possible.
Corrected entry: When the T-800 first sees John Connor on his bike with his friend, he zooms in to check the identity, and the close-up shows us Johns face with his hair nicely done and hanging down - however, wouldn't his fair be thrown backwards, accounting for the speed they were going on the bike?
Correction: That was a photo that the Terminator had, so he could identify the target.
That's not correct, the image we see in the T-800's vision is supposed to be a zoomed in image of John Connor on his motorcycle, but is a still photograph.
Correction: "Surely the truck is diesel" does not mean it absolutely is, it MIGHT be petrol powered. The benefit of the doubt applies.
