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)
Corrected entry: Before the Terminator is lowered into the steel, he says "goodbye." You can see his breath revealing the actual temperature on the set.
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.
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?
Corrected entry: The T800 uses the old trick of hot wiring a car by ripping off the steering column cover in the car in the desert. But in doing so, he is grimacing. Is it hurting the big, strong cyborg?
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)
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.
