Visible crew/equipment: In the scene where John, Sarah, and The Terminator are in the Cyberdyne building. They have just come down in the lift into the lobby where the SWAT team are waiting and firing gas cylinders. Arnie says his "I'll be back" and walks out of the lift. The SWAT team issue various instructions, then say "OK - drop him!". Now - look carefully. The second they start to fire, look at the SWAT member who is furthest to the left and standing up. If you look right by his shoulder as soon as they start firing, what looks like a crew member walks into the scene, with his hands in his pockets. (01:58:51)
Trivia: Eddie Furlong was warned, at the very beginning of the scene where he rides out of the mall and the T-1000 is chasing him, that Robert Patrick could run exceptionally well. Furlong confidently said that Patrick wouldn't catch him. However, on the very first take, Patrick ran right up and tapped him on the shoulder. So if this was real life, the human race would be in trouble.
