Continuity mistake: When Sator is on the highway looking for the Plutonium-241, he's seen coming out from the car and then closing the door, but after he checks in the BMW's glove box and returns to his car, the car door is open without anyone touching it. (01:31:58 - 01:32:49)
Continuity mistake: When the Protagonist inverts himself and gets into the Saab - which is the car that overturned in the previous chase scene on the highway - you can see the car's tires resting first on branch lines' tracks, but in the next shot the tracks are gone and the ground is dusty. (01:31:41)
Continuity mistake: When Sator is in the blue room after walking through the turnstile, he picks up Kat, puts her against the window, counts down from three to one and shoots her. Whilst he is counting down, he has his hand on Kat's shoulder. The camera then changes to a different angle where his hand is now on Kat's upper arm, and then moves onto her shoulder. Sator then pulls Kat away from the window with his hand on her upper arm. (01:24:58)
Other mistake: Sator and another man run into the turnstile when the soldiers arrive and exit on the other side. As soon as the two of them enter the opposing room, the other man immediately begins running towards the door on the opposite side of the room, to open it. Whilst he is doing that, Sator begins watching the events that just occurred in the opposite room unfold in reverse, all of which last for about ten seconds. But after those ten seconds, the man is still shown running towards the door. The distance between the turnstile and the door was not very far and it shouldn't have taken that long to run to it. (01:24:28)
Continuity mistake: Just after the interrogation has been shown from Sator's perspective, it cuts back to the Protagonist and the other soldiers in the present. There is a shot of a medic looking over Kat, where his left hand is shown placing his gun on the ground. It then cuts to a different angle where his left hand is now placed over Kat's stomach. (01:25:41)
Continuity mistake: The Protagonist and Priya are walking along a pathway in a park whilst talking about the creator of the algorithm. There are multiple points in this scene where the direction of their head changes between cuts. When the Protagonist says "The past", Priya is looking forwards, but when the shot cuts, she is looking more to the left. Later, Priya says "Nine sets of the most closely guarded materials in the world" and the Protagonist is shown looking at her, but when the shot cuts, he is suddenly looking forwards. She then says "The best hiding place possible" looking at the Protagonist, but is then looking forwards in the next shot. Seconds after that, when she says "Find and assemble the algorithm" she is looking at the Protagonist, but is then shown looking forwards when the shot cuts. After the Protagonist asks why they chose Sator, Priya replies looking at the Protagonist, then looking forwards, then looking slightly to the left, then back to looking forwards in the next shot. (01:47:55)
Continuity mistake: When the bodyguards begin to pull the Protagonist and Kat out of the inverted vehicle after stopping it, Volkov is the only person who is first shown grabbing onto the Protagonist to try and pull him out. It then cuts to a closer shot, and a second bodyguard has suddenly appeared, to help Volkov pull the Protagonist out of the vehicle. (01:21:57)
Continuity mistake: When the Protagonist and Neil first see the inverted vehicle driving backwards towards them, there is a bridge (with an Alexela sign) shown in front of them and just ahead of the bridge is a gas station shown to the right of shot. It then cuts back to the Protagonist and Neil, where Neil asks "The hell is that?" and when it cuts back to outside the windscreen again, the bridge (with the Alexela sign) and the gas station are no longer visible, presumably having driven past them. It then cuts to a shot focusing on the Protagonist, and when the shot cuts back to the inverted vehicle bumping into the wing mirror, they are suddenly behind the bridge and gas station again and are yet to drive past it. (01:18:30)
Continuity mistake: When the Protagonist and Neil walk into the two rooms with the turnstile in the Oslo Freeport, just after the Protagonist tells Neil not to touch the bullet holes in the window, Neil asks "What the hell happened here." At this point, his head is turned about 90° to the right. In the next shot, his head is turned more forwards and much less to the right. (00:44:50)
Continuity mistake: In Stalsk-12, Wheeler and a blue team soldier take cover inside a house in which chunks of rubble have been blown out of the wall. When the pieces of rubble begin to reassemble back into the wall, Wheeler runs out and the soldier attempts to run out but gets sealed back in. Right after Wheeler runs out of the hole, and the soldier begins screaming, he is shown standing upright. But in the next shot, right before the rubble chunks go back into the wall, the soldier can be seen now kneeling over the hole in the wall. (02:05:45)
Continuity mistake: When the Protagonist and Kat are speaking shortly before the journey to Stalsk-12, in the shot where Kat leans in to kiss him on the cheek, the oxygen mask that the Protagonist is shown wearing is positioned hanging directly in front of his mouth. The shot cuts to focus on Kat, but when it cuts back to the Protagonist, the oxygen mask is suddenly hanging in front of his left cheek. (01:55:34)
Audio problem: When Kat is speaking with the Protagonist shortly before he inverts himself, there is a shot focusing on the Protagonist where Kat is shown in the corner of shot saying "I didn't get to say goodbye", but her lips don't move. (01:54:30)
Continuity mistake: When the Protagonist approaches Priya after inverting back in Oslo, right as he says hello to her, on Priya's left, a woman and man can be seen. The woman is wearing an orange cardigan, blue jeans and a handbag over her arm. The man next to her is holding a plastic water bottle. The camera then cuts to an angle in front of the Protagonist and Priya, where the man and woman are suddenly further behind them. (01:46:43)
Continuity mistake: On the shipping container, Neil injects Kat with some medicine in a syringe. Whilst Neil says "The faster you sleep, the more you heal", he is shown with his left hand holding Kat's arm and has his fingers positioned under her arm. It then cuts to a closer shot of Kat, where Neil's left hand is now positioned on top of her arm. (01:37:58)
Audio problem: Just before the Protagonist is about to go outside fully inverted, Wheeler is shown pushing a button on the wall which opens a large door. She then says to him "Friction and wind resistance are reversed", but her lips do not match up with what she is heard saying. (01:30:13)
Continuity mistake: Whilst Wheeler is explaining the rules of inversion to the Protagonist shortly before he goes outside, as she is saying "Gravity will feel normal but appear reversed for the world around you", she is shown holding a small tank of oxygen in her left hand and begins attaching it to a tube shown in her right hand. The camera then changes angles and the oxygen tank is now in her right hand and the tube is suddenly attached to the tank. (01:30:02)
Continuity mistake: When the Protagonist, with Neil's help, is trying to stop the inverted car in which Kat is locked up, the door's window is lowered differently depending on the shots. (01:20:36)
Continuity mistake: When the Protagonist and Neil are driving away from the inverted vehicle, there is a shot where the Protagonist is shown looking forwards out of the front windshield, but when the camera changes angles, he is suddenly looking to the right to face the inverted vehicle. (01:19:23)
Continuity mistake: When the Protagonist is being dragged into the Freeport by two of Sator's bodyguards, an inverted Sator is in the background, dragging Kat by her arm on the opposite side of the gate. A closer shot of Sator dragging Kat is then shown, where he now has his arm across her abdomen. (01:22:10)
Continuity mistake: Just after the Protagonist has obtained the case containing the Plutonium-241 and is back in the car with Neil, he opens the case and his right hand is shown placed on top of it. It then cuts to a different angle and his right hand is suddenly touching the Plutonium-241. (01:18:09)
