Continuity mistake: Near the end of the film, Adam and his clone make a jump for the helicopter to escape the explosion. In one scene, you'll see Sport Jacket Adam holding the ladder to the helicopter with Leather Jacket Adam holding onto the legs of the first Adam. After a cutaway scene, you'll see these two have switched places (Leather jacket on ladder, Sport jacket on bottom). The next time you see them, they're switched back in the correct order. (01:52:30)
Continuity mistake: In the car chase early in the film, we see Adam drive the Cadillac down a flight of stairs. A shot from the front show the car going over the top of the stairs, and as it bounces the lights going out. By the time we see the car again, the lights are full on. (00:28:25)
Continuity mistake: When Robert Duvall drops the folders on the floor in front of Drucker, notice they are all spread about in a mess. Then when Drucker goes to pick them up, they are all in a neat pile except for three of them. (01:20:45)
Continuity mistake: Towards the end of the movie, in the scenes involving the dying Drucker (Tony Goldwyn) and his half-formed clone, blood on the dying Drucker keeps disappearing and reappearing. In one scene he is bleeding out his mouth and down the front of his throat. The camera cuts away and when it comes back his throat is clean. Yet in the next scene his throat is bloody again. (01:46:10)
Continuity mistake: When Drucker jumps from the roof onto the glass at the end(to avoid the rotors of the Whisper Craft), the establishing shot shows him on the last panel of glass next to the wall. However when you see Drucker fall from the inside shot, he falls from the middle of the glass roof and no wall is seen anywhere near him. (01:51:50)
Continuity mistake: When clone Adam is running towards the helicopter and gets shot in his left leg. The other Adam sends the helicopter away. When the helicopter comes back, clone Adam limps on his right leg. (01:50:40)
Continuity mistake: When Schwarzenegger returns to his company and removes the photo of him and his family from his locker he then looks in the mirror at his shaving cut, in doing so lifting his cheek right up to see the cut which is obviously under his chin. In all the other scenes however, the cut is clearly visible without having to pull or distort the face. (00:48:15)
Suggested correction: First off, Adam looks at his chin before going to the locker. However, he never distorts his face to see the scar. Any pulling is just fully him examining the scar. Plus, when Hank asked to see the scar, he had a different angle to see the scar than Adam would have of himself in the mirror.
Continuity mistake: When Talia is first killed, while in the Cadillac, the passenger door is blown off. When Adam drives through the water there's an inside shot of him and you can tell the door is back on for the scene. After going down the stairs there's the same inside the car shot of Adam and you can see the door is missing.
Continuity mistake: When Adam smashes the TV in the police station with his elbow the picture on the screen goes out and it goes to black but when it cuts to a different angle of him smashing the screen the picture is still on the screen and flickers out again. (00:43:10)
Continuity mistake: After Tony Goldwyn is done making his "saving the dying boy with the brain tumor" speech to the press he puts the microphone down on the podium and the next shot shows him turning and putting it down a second time. (00:33:25)
Continuity mistake: When Arnold is jumping out of his car when it is about to go off the side of the cliff, he would have to open the driver side door, and jump out that way. Still, when we see the car go through the air, into the water, the driver side door is closed. (00:29:45)
Continuity mistake: When Adam is in the police detention room, he props a chair under the doorknob to keep anyone from entering. The chair is propped with the seat up, but when the police break in and the chair flys away from the door, you can see that it had been positioned with the seat down. (00:43:05)
Continuity mistake: Near the end of the movie there's a scene where the lead antagonist meets his clone, the antagonist's sweater has a hole in it from where he was shot. The clone needs the antagonist's clothes and takes them from him, but the hole from the sweater is missing. In another scene, the hole is present. (01:45:40)
Continuity mistake: In the final shoot out on the roof there is a quick shot of Arnold firing a gun wearing the grey security outfit he stole from the guard earlier in the film. The only problem is at the time one Arnold is wearing his leather flight jacket and the other is still dressed in the sport coat outfit he wore to his daughter's school. This is obviously a shot from an earlier scene they used again later.
Continuity mistake: When Dr. Weir is about to show Adam the recording of Drucker's memory, we see him open the drive and put the disk in it; and then in the close-up shot, he does it again. (01:12:00)
Continuity mistake: When a shot of the city is shown from the air (near the beginning of the film), at the top of a building you can see the logo of the Canadian Imperial Bank of Commerce - this is supposed to be set in America.
Continuity mistake: When Adam enters the building with the girl's thumb, he gives the cooler to the security guard who begins to remove the tape, then the shot cuts to a view of Adam across the desk and the tape is back up, then when it goes back to the POV of Adam looking at the guard, the tape is back up. (01:04:25)
Continuity mistake: After Arnold buys the Sim Pal doll and he's in the taxi going home, he tells the doll, "Go to sleep, Cindy...go to sleep." The doll stops talking and closes her eyes. When Arnold gets out of the taxi carrying the doll and walks up to his house, her eyes are open. (00:22:10)
Continuity mistake: When the Cadillac crashes through the neighbor's fence, it loses the rear driver side hubcap. Later, in a few shots of the tires, the hubcap is back on and then off again.
Continuity mistake: When Arnold sneaks into the building using the girl's finger, he opens the lid on his little cooler to get his gun out. He throws the lid on the ground, the camera angle changes, and the lid is back again, then the angle changes again, and the lid is gone again. (01:06:15)
