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 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: 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: 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: 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: 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: 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: 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: When he arrives at the club he texts "I'm here" and receives the reply "bathroom" but the texts are on the wrong side of the screen. It looks as if he replied "bathroom". (01:20:10)
Other mistake: The driver tells his partner that his firearm is empty, and he has no bullets in it. In the beginning he was given a loaner firearm until he could purchase his own. He's been with the company for a while now so that makes no sense. Also, for a trained professional who killed six robbers with precise accuracy it's hard to fathom he would not notice his gun weighing less. A loaded Glock 17 weighs 8.5 ounces heavier than an empty one. Plus the guards carry spare magazines, where are his? (01:20:00 - 01:22:30)
Other mistake: At the end of the movie where they are looking at the headstone of Jake Hobart, the date on the bottom of the stone is April 3 1913, despite dying shortly before the Titanic sank in 1912.
Other mistake: When Dean compliments Les on the great driving making up for a year of boredom, Les looks around up in the air in a direction away from the car, then suddenly says "there's a scratch on my car." He then looks down on the car at the scratch and shows Dean. He said the "scratch" line before actually seeing it.
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: Tony Danza's character introduces himself as "Tony." When the credits are rolling at the end of the movie, we see that his character's name is Terry, not Tony.
Other mistake: As Ray and Emma are drifting around San Francisco in the speedboat, they come across a Navy ship that just got carried in with the tsunami and is now leaning 20 stories high against a building with water dripping from it. If the tsunami were that high, with the wave having now receded back down to ground level, why are there still fires burning down low? The wave would have snuffed them out. (01:30:40)
