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: 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: After Sonny is shot on the causeway, there are a very large number of bullet exit holes visible on the sides of the tollbooths, which could only have been made if the gunmen shot through the walls (not the windows) of the buildings from the inside. This is common in movies. In real life, bullet entry holes in wood appear as small black dots, not the more dramatic-looking splintered gashes made on the other side of the wood as the bullet exits. (01:52:40)
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: When De Niro and Bridget Fonda are talking and trading hits off of bong, alone in the apartment, while they're talking there comes a pause where they both look at each other with their mouths closed, and you can here someone coughing in the background.
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: 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 the bear falls on Eddie, they are facing the same direction, but Eddie says that he knows the bear is a girl "Because its vagina is on my ear."
Other mistake: On board the USS Reliant as it orbits Ceti Alpha 6 the systems panels show ship diagnostic diagrams including a wire model of a Constitution class hull, something the Reliant doesn't have. (00:13:01)
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)
Other mistake: The hurricane winds blows cars around, but the actors can walk against the wind and climb cellphone towers. Plus the hurricane "eye" hits the town, but trucks ride out on a road with dry leaves and dust.
Other mistake: In the first scene with Randy telling Jamie Lee Curtis to turn around, the reflection in the TV never mirrors the actual position of Jamie Kennedy. (01:22:30)
Other mistake: When we see the numbers for the coded entry to Alice's weapon, the order of the numbers is 1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - 0 - 9. The 9 and 0 are the wrong way round. (00:47:40)
Other mistake: When Memphis and Kip are hiding from Johnny B and his crew in the cafe following the ambush, Memphis devises a plan to make good an escape. He sends Kip out to use the tow cable on the heavy tow rig to destroy Johnny B's Mercedes. First angle shows a cable wrapped around a rear A-arm of the vehicle and the hook connected to the cable, the next shows a hook directly attached to the front axle, which is the one that gets torn from the Mercedes when the tow rig pulls away. Additionally, a different cabling rig and loose cabling used in the stunt are strewn behind the car. So even if Kip somehow made 2 connections without being seen or heard, the rear rig is different than the one shown in the first shot. (00:51:00 - 00:53:00)
Other mistake: When the main characters are in the motel and they hear the moth flying outside the window, Stu, the creepy deputy with the glasses, picks up a shot gun and racks a round into the chamber. In the next shot of all of people firing at the moth through the window, Stu is now holding his revolver and fires with it. When he runs of out ammo with the revolver he picks up the shotgun again and before firing racks the pump again. Since he already did that the gun should have ejected the unfired shell that was already in the chamber from earlier, but no shell is ejected.
