Other mistake: On his own computer, Sean looks up his son's file, which states the boy died immediately and his date of death was September 9th, 1991. When Eve and Castor (as Sean Archer) are at the cemetery, the date of death on the headstone is September 24th, 1991. (00:21:15 - 01:14:50)
Other mistake: When the Angels are in the bar in Mongolia, and Alex is trying to get out of the trapdoor with Ray Carter, a guy falls over the trapdoor entrance. When Dylan tries to move him, and sits down on top of him, the trapdoor falls in. Wouldn't that crush Alex and Ray Carter? (00:04:55)
Other mistake: In the scene after Arnold kills the construction hoods he goes home to Sharon Stone and tries to convince her that it was real by showing her his bloody hands with which he was grabbing her shoulders, yet there is no blood on her or the appliances he turned off upon entering the apartment.
Other mistake: When Kimble takes the elevator to the conference to confront Dr. Nichols, he presses a button, but the one beside it is the one that actually lights up. In this particular elevator, the button he pressed is the one that should have lit up.
Other mistake: In the scene where Ripley throws the basketball at Johner, Christie says to Ripley, "Ok, I've got a new game, tag .." He hits her with the handles straight in the face once, he misses the next shot, misses again, and Ripley hits him to the ground, but you neither see or hear the handles fall. (00:23:15)
Other mistake: Towards the end of the movie, Clayton has two wounds visible on his face. These wounds keep changing length and shape throughout the scene.
Other mistake: The shot of Big Ben destroyed by lightning looks strangely like the Big Ben exploding in the film "Mars Attacks" (1996).
Suggested correction: Whether or not it is the same footage or just similar, it's not a valid mistake as there no continuity or factual errors involved, etc. It's trivia at best, if the two films can be tied together and there's documented reports of someone involved in the films admitting the footage was reused.
Other mistake: An antenna can be seen on the building above the grain warehouse.
Other mistake: During the scenes in Beirut, we see a picture of a militiaman firing an RPG at an armored vehicle. If you look at the launcher, you can see that there is no grenade in the launcher when it is "fired."
Other mistake: When Cindy asks 'What did you do with Sully?', surely she must have known he'd been dropped off the cliff as she was standing about five metres away? (00:40:00)
Other mistake: The alien that comes out of the dog is a lot bigger than the actual dog just seconds after it appears. This only applies to the theatrical version, as in the extended version the alien comes out of an ox.
Other mistake: While fighting Mr. Freeze (and Bane) at the Gotham Observatory, Batman, Robin & Batgirl all have batsuits on, with silver bat (or robin) symbols on their chest. But while they are giving Alfred the cure to Stage 1 of McGregor's Syndrome, for some reason they have changed clothes before giving him the cure. Because now (other than the fact that they have all taken off their masks) Robin has on his original robin suit (with the red robin symbol across his chest) and Batgirl has on a gray t-shirt. (01:55:25 - 01:56:15)
Other mistake: When Don and his father are driving home and Don's father throws his ring out the window, Don gets out to search for the ring and you can see wet marks on his shins from kneeling on the wet road. However, he hasn't knelt down yet. It must have been from previous takes. Also, when he gets up after kneeling down, his jeans are dry. (01:01:50)
Other mistake: During the beginning of the freeway chase scene, a "Maximum Speed 65" sign can be seen along the freeway wall in the slow lane that is facing the opposite direction of traffic. Freeway traffic in that lane would only be able to see it in their rear-view mirrors. (01:25:20)
Other mistake: After the one bad guy crashes into the giant vat of toxic waste, hardly any of the liquid from the container spills out for the first two shots. Then a few cuts later, almost all of it pours from the back of the truck. Judging by the size of the hole it left, more liquid should have been coming out around the truck, not just through it. (01:29:00)
Other mistake: Major Turner tells Reacher that the men Parasource killed were shot twice in the back of the head. During Prudhomme's telling the images show the downed soldier on his back. The other is shown being shot and falling on her back. Then the two kill shots each. They couldn't have been in the back of their heads.
Other mistake: The caption onscreen when the C.I.A. Headquarters are shown reads "Langely, Virginia". It should be Langley. [Might be Netflix only].
Other mistake: During the mine scene, we see Stacy Sutton in very tight miner's overalls. Then, Mayday rips them off to reveal the white dress she was wearing beforehand. There was not enough room in those tight overalls to hike up or bunch the skirt in any way for her to move her legs or have both legs in both pant legs. (01:47:05)
Other mistake: When Quin is cutting the plane that's stuck in a tree, he uses a saw, that looks brand new. He's just been chased by pirates and jumped off a cliff - where did he get the saw from? Anything in the plane would be rusty by this point.
Other mistake: When Batman is video calling the Riddler and passes the phone over to the D/A, you can see Batman's face still looking at the phone in the reflection of the Riddler's glasses.
