Continuity mistake: Ep. "Samson and Delilah" - When the Jeep Cherokee flips, it lands on the driver-side/rear corner of its roof, completely collapsing that corner of the roof. The camera angle changes and instantly the Jeep is landing on both of its driver-side tires, roof intact, and rolls onto its left side. The angle changes again, and the collapsed roof is back as the Jeep slides a bit more before the shot changes again, and the undamaged roof is shown as the Jeep rolls onto its roof and comes to a stop. The camera pans around the rear of the wreck, and there is no roof collapse at either rear corner.
Continuity mistake: Ep. "Samson and Delilah" - As Derek sits at the table, Sarah is digging jelly from a jar with a knife, moving it onto toast that sits on a plate on the table. The shot instantly reverses and the jar is on the table and she's spreading the jelly with the knife on the toast she now holds in her hand.
Continuity mistake: Ep. "Samson and Delilah" - Sarah carries a plate with a sandwich and a tall glass of milk for John. After talking with Cameron for a few moments, she heads to John's room, arriving with the plate and sandwich, but no glass of milk, and with some of his clean clothing.
Continuity mistake: Season 2, episode 21, "Adam Raised a Cain." While in the garage of Ms. Weaver's house, a terminator, out to get Savannah, takes four bullets from Sarah in the back. Later as you see the terminator go after John and Savannah, you can see his back as he is coming up some stairs, and the terminator now has five bullets holes in its back.
Continuity mistake: EP "Goodbye To All That": On the firing range when John Connor fixes the stoppage on the rifle, his shooting glasses are on his head, when he hands the rifle back, the glasses are now over his eyes, and in the next shot they are on his head again. Not enough time has occurred between shots for this to happen.
Continuity mistake: As the FBI agent shows his ID to Dixon, it is in his right hand, the badge end up. He holds a folder in his left hand. The camera cuts away for just a moment, then returns to show the ID in his left hand, badge to the right, and the folder is in his right hand, all without enough time to make the switches. (00:08:55)
Continuity mistake: As Cromartie is approaching the Dyson home, he carries an automatic rifle with his right arm. As he makes a turn toward the left, he lowers the rifle down to his side, pointing it at the ground. He hears a car start and an instant camera angle change shows the rifle is still pointed forward and upward, not down, with no time for the change. (00:32:55)
Continuity mistake: When Sarah throws Cameron out of the window after the rigged safe deactivates her, she lands on the roof of a car at the bottom with her legs straight, arms straight at a diagonal angle and her head looking straight up. But four shots later, she is lying on the car with her legs bent over the roof, her arms at a horizontal angle and her head looking to the left.
Continuity mistake: After Sarah lies to get Cameron away from the cop, the collar on Cameron's jacket is folded forwards over her neck as she walks down the alley with Sarah. She then tells Sarah that it's 13 miles to walk home and that they need another car. In the following shot, her collar is folded back towards her shoulders.
Continuity mistake: As Cameron is questioned about the girl that commited suicide, the interviewer holds a photo of one of the mostly-black posters. When we see his view of the photo, the white letters spell 'DAN', but before and after that shot, when we see his face, we can see through the photo, and it only reads 'A', which is a different poster seen earlier in the same episode. (00:22:55)
Continuity mistake: When Sarah, John, Cameron and Derek go looking for Barbara Chamberlain's body, they stumble upon Jessica Peck's body instead. Derek reads her ID and says, "Who the hell's Jessica Peck?" Cameron then says, "A threat to Skynet." As she says this, her hair is partially covering her right eye. But in the next shot it's tucked back behind her ear.
Continuity mistake: In the scene where Derek shows John his past self playing baseball with Kyle Reese, Derek hits the ball towards John, John picks it up and then gives it to Kyle. As Derek hits the ball towards John, he is holding the bat at an upwards angle towards the right. But in the next shot of him, he is holding the bat at a downwards angle towards the left. The ball also travels in the opposite direction to what it did previously.
Continuity mistake: All shots of the Jeep Cherokee prior to it crashing (and during the process of flipping over) show that it wears factory-optional silver steel wheels of a 'star' style. But as the wreck settles upside-down, it's wearing plain steel wheels (like those found under full wheel covers or on a spare tire).
