Corrected entry: Kyle tells Marcus that you don't want to go out during night because the HKs have infrared. Contradicts what Kyle tells Sarah in the original movie: "You stay down by day, but at night you can move around." Doubt this was a mistake, but more of a difference in technology in the 25 years between production of the two movies. (00:26:50)
Corrected entry: Towards the end of the movie the bald girl (Skynet) explains everything to Marcus. How he is programmed to infiltrate the resistance and ultimately bring John Connor to the Skynet base. As a result of her story, Marcus rips out the chip and eventually saves John Connor and helps destroying the base. As I interpret it, that scene is only there to explain Skynet's master plan to the movie audience. If Skynet is smart enough to predict everything so far, it should be smart enough to realize Marcus might intervene. There is no logical reason why Skynet would jeopardize everything at this point.
Corrected entry: In the scenes where Marcus is repairing the Jeep, you can see plants growing between the front seats. Yet a few scenes on, Marcus shoves Kyle out of the Jeep, saying, "I am driving," and the plants are now gone.
Corrected entry: When Kyle captures a terminator by his foot using a cable, the terminator shoots his own foot off to get away. Since the cable would appear stationary since it is attached to the terminator, it would have been just as easy for it to shoot the cable a mere 6 feet away instead of blowing its own foot off.Something like a terminator that is designed to kill everything should have a targeting system that can engage a cable at 6 feet.Robertus
Corrected entry: When Blair frees Marcus from the resistances chains, he falls face down (slightly tipped up), but he lands on his back, though he was falling straight down.
Corrected entry: Sarah's tape is played back differently than when she recorded it in the first movie. For example, in T1 she says, "If you don't send Kyle back, you can never be" before she says "A person could go crazy thinking about this." However, here in T4, the two lines are reversed. She also has a line about Kyle being a teenager, which is never said in T1, and in fact wouldn't make sense. Sarah was able to postpone Judgment Day after T1 which means that she changed the future - and it is through this altered future that Kyle is a teenager at this point. She couldn't have known this in T1.
Corrected entry: When Marcus and Kyle are getting the Jeep in the wide shot a crew member is visible blowing up dust on the side of the mountain in the valley. (00:33:05)
Corrected entry: When John infiltrates Skynet and frees the human prisoners, a screen depicts an overhead view of all the cells (or at least the section of cells where Kyle Reese is contained), with the prisoners being represented by red dots. When he unlocks the doors, one can observe on the screen that all the doors are open, even though Kyle's door is still closed.
Corrected entry: During the scene where we come to the resistance air hangar at night, you can see a smoke grenade rolling along the floor near the nose of the plane to create smoke for the scene.
Corrected entry: In John Connor's first confrontation with Marcus Wright, he claims that Wright killed his father, Kyle Reese. But at this point, Connor has not yet even met Reese, much less sent him back in time to impregnate Sarah Connor and ascertain his birth. If Reese was in fact dead as John Connor believed he was, then Connor wouldn't even exist.
Corrected entry: In the scene involving the Resistance fighters testing the 'control signal' on a hydrobot, a woman states that they have 'burned out' its transmitter, so it cannot send info back to Skynet. However, when Marcus talks to Skynet in the form of the dead doctor Serena Kogan, she shows him footage from that hydrobot of John Connors face.
Corrected entry: How come the resistance didn't use the signal that shuts down machines on Marcus when he escaped from their facility? You could say they did try to use it off-screen and it probably didn't work as the signal is fake and Marcus is probably protected by its effect. But if the resistance finds out the signal won't work on all machines they would call off their attack. So why didn't they try to use it on Marcus?lionhead
Corrected entry: When her human attacker points the HK USP pistol at Blair it makes three loud audible clicks as he cocks back the hammer. A real HK USP makes only two light clicks.
Corrected entry: In the first movie, Kyle Reese explains to Sarah Connor about the Terminators as infiltration units, with human tissue, metallic endoskeleton, sweet, bad breath, etc; so they are very hard to spot. Reese then says to her, "I had to wait 'till he moved on you before I could zero him". Reese didn't know the look of the T-800 in 1984. But in "Salvation" Reese saw his face. Besides, John Connor knew this Terminator since he was a child. John and Kyle where together, so Reese should know the appearance of the Terminator before the time travel to save Sarah.
Corrected entry: At the end of the film when Marcus offers his heart to John Conner to save his life, what are the odds that he is an exact match for John. Many tests have to performed on a potential heart transplant patient to determine the tissue type matches and won't reject the heart. Also, it cannot be performed on the "fly" in a make shift army hospital tent. It requires many surgeons and trained transplant personal in an extreme sterile environment and takes many hours to perform.
