Continuity mistake: In the very first scene when Seagal first gets off the helicopter we see that he's wearing a navy blue shirt tucked into his jeans. In the next shot he's shown wearing the yellow suit but instead has a white shirt on underneath instead of the navy blue one.
Continuity mistake: In the scene when Nick Nolte is arguing in the parking lot, he unlocks his car door, but his window is rolled down in the same scene.
Visible crew/equipment: A boom mike is reflected in the car window, when Alex pushes Hugo's car into the lake.
Continuity mistake: In the beginning of the film when Jack Nicholson hits the wolf, his car spins around 180 degrees in the snow, but there are no marks from the wheels in the snow when he approaches the hit wolf. (00:03:25)
Other mistake: The kids dare each other in a decrepit water tower which is mysterious in a number of ways: 1) Draining the water causes a powerful vortex, but the water level is not going down. 2) No one seems to work the bottom valve, but the vortex comes and goes. 3) It is absolutely impossible that anyone could swim through such a vortex, but Stu does. 4) The rotten roof breaks under the weight of little Billy (the ice-cream excess?) but carries his brother who weighs about 4 times as much. (01:27:00)
Continuity mistake: During the trial when Beverly is cross-examining Mrs. Ackerman, her neighbor, she asks if those were her scissors found sticking out of Mrs. Sterner's stomach. That's not where the scissors should have been found. After stabbing Mrs. Sterner with the scissors, Beverly pulled them out and threw them at the husband twice, both times they ended up sticking in the walls, and that is where the scissors would have been found when the police arrived.
Continuity mistake: When Schwarzenegger's urine is tested for pregnancy, the colour of the contents of the vial does not stay the same for two consecutive shots.
Continuity mistake: When Veronica give Dante the lasagna, Dante syas he will be closing the store, but he doesn't find out that he has to close until the next scene.
Suggested correction: Dante actually says that his boss has not shown up yet. It's already past noon, the time when he expected to leave. He probably suspects that he will be working much later. I've had similar jobs, and it was not surprising if a late manager/co-worker ended up not coming in at all.
Factual error: What on earth is the conductor at the premiere of the 9th doing with a baton? This was not used until around 1849, and the premiere of the 9th is in 1824.
Continuity mistake: In the scene when Rudy is holding a colt python to the hotel owners nose, in the next shot, the gun suddenly changes to a smith and wesson revolver.
Continuity mistake: In the last game of the movie you can see that Ray Mitchell (Angel Player) hits a home run to tie the game. If you look you can see that the home run ball goes over the fence and out of the stadium but then after they change cameras to Ray and then back to where he hit the home run it shows a man with the ball in his hand as if he caught it.
Continuity mistake: When Tommy Lee Jones pops into his local Irish boozer for a pint of what is supposed to be Guinness, it is clearly not a pint, it is clearly not Guinness (flat Coke, more like), and the level of said beverage in the glass fluctuates wildly and out of synch with TLJ's swigging.
Continuity mistake: Immediately prior to Preston and Shay dancing in the fountains, Shay is wearing high heels. While dancing in the fountain, she wears flats. After leaving the fountain she is once again wearing high heels.
Factual error: There is a shot with Wesley Snipes and Gary Busey aiming one another just to pull the triggers and discover that the guns are out of ammo. In fact, after the last shot (of the pistol, not the movie) the slide of a semi automatic pistol is retained open by the empty magazine, and doesn't return forward as we can see in the shot (of the movie, not the pistol). The reverse mistake is very common in movies, when the armorer loads just one round to be shot (in the movie as well as the gun) and the actor keeps fighting or menacing with an unloaded, breech opened gun.
Visible crew/equipment: When Li's sons is doing "pushups" on one finger while flying up into the air you see the wire attached to him. (00:29:50)
Factual error: When Julia Roberts drives away from the building where she finds the dead body of the boy with "LD" written on his hand, it is raining heavily. Yet, as she accelerates, there is an extended sound of tyres screeching on a dry surface.
Revealing mistake: When Beauty is nursing from his mother, you can see that the foal used was a filly and not a colt when "his" tail swishes from side to side.
Continuity mistake: At the final fighting scene (David Sloan vs.Tong Po), you can see that Tong Po's hair (a half shaved head with only a ponytail on it) is as fake as it can be: everytime when he moves his head a bit to rough around (sweeping his ponytail around while fighting) clearly shows that he's wearing a special kind of wig attached to his head. That 'wig' is so badly attached that it looks like he's got rimples on the back and on top of his head.
Continuity mistake: In the water tank sequence Cranston dives to the bullet holes to get air. When he dives down there is a camera shot looking up at him from the bottom of the tank showing that there is plenty of air left at the top, no doubt left there so that the actor would not drown. And; for the sealed tank to fill completely there must have been a way for air to escape rapidly from the top. When the tank was full water kept pouring in and would have escaped the same way. When Margo arrives there is no water coming off the top of the tank.
Suggested correction: The tank is to test pressure. Had water been escaping so would have Cranston.
Continuity mistake: In the bus scene, when Stallone goes on the bus the number is 9372, when he kicks the bad guy out of the window the number on the bus' side is 9369.
