Revealing mistake: Look carefully at the metal bar with which Arnold secures the doors of the van with the Vet inside. As he bends the bar straight so he can open the doors, it vibrates a little indicating it is a rubber fake. (00:43:15)
Continuity mistake: In the crane chase scene, there is a point where the last remaining ambulance collides with the back of the Toyota. You see the ambulance back off and the right headlight is smashed and the housing is dangling. The headlights are also off. The scene cuts to the rear-view mirror of the Toyota. You briefly see the same ambulance with its lights on and both headlights are intact. Shortly thereafter, they cut to a behind-the-back shot of Arnold as the same ambulance starts to flip. The tail lights are on. It wouldn't be brake lights since there is no driver and the Terminatrix certainly wouldn't remotely apply the brakes.
Continuity mistake: During the chase scene with the veterinary truck and the terminatrix, the damage to the truck is constantly changing. In one shot the hood of the truck is bent upward, in the next shot it is straight and undamaged.
Continuity mistake: When the crane flips over the arm is missing when it is seen sliding across the road.
Continuity mistake: When the three leads leave the rest area in the mobile home to go find Cate's father, it's about 3.30pm (we hear reference to 6.18 pm and it's in 2 hours 53 minutes). After the conversation where T101 tells that he killed John, you see the car from the outside. You can see on the shadows that the sun is so low, it must be very close to sunset. Shortly afterwards, during the next conversation, it is bright daylight again and it stays so during the rest of the outdoors scenes. (01:08:20)Jacob La Cour
Continuity mistake: When the TX runs the crane through the glass corner of a small building while chasing the tundra truck, the flashing orange lights on the top of the cab are missing. These lights return on the next shot.
Visible crew/equipment: When the TX's crane drags the terminator through the building's glass facade you can see the camera mounted in a cage on the back of the crane when the viewpoint changes to the inside of the building. (00:34:10)
Revealing mistake: When the T-X is trying to get Kate out of the car, she rips the door off the truck and pulls Kate out. Kate goes flying through the air and lands on the tarmac. However, if you watch the floor closely just as she lands, you can see that the floor actually wobbles and shakes. It is obviously not real. (00:24:35)
Continuity mistake: A headlight breaks loose on the ambulance after hitting Arnold's motorcycle. The next shot when the TX is looking in her rear view mirror, the ambulance has two flawless headlights.
Continuity mistake: The crane's arm is draped in cables, wires, and even a partial telephone pole right before Arnold is dragged through the buildings glass facade. The next shot before impact the crane's arm is clean. (00:34:00)
Continuity mistake: When the TX pulls up to Jim's Burgers, notice the umbrellas in front of the store and the "in-out" arrows on the road. Asking for Jose Barrera at the drive-through speaker, she drives in and shoots him from the passenger side of the car and exits on the same side of the building she came in. You can see the front of the store with umbrellas upon entry and exit, yet the speaker has disappeared. (00:16:30)
Continuity mistake: The hubcaps on the hearse come off but are back on in later scenes. (00:59:20 - 01:00:30)
Revealing mistake: During the opening credits, the Terminatrix steals a woman's car. She uses her mobile phone to dial a number and successfully connect to a computer. However, you can see that the phone has no reception, making a phone call impossible. Battery life is the right hand gauge, and signal strength is the left hand one, with no bars. (00:07:25)
Continuity mistake: When the Terminator is slamming his fists again the truck trying to fight his new programming, the damage to the truck changes between each camera angle. Watch the passenger front tire collapse under the truck in one scene and then it's just at an angle on the next. (01:28:10)MCKD
