Revealing mistake: When the Angels are fighting the "Creepy Thin Man," right before Drew Barrymore lifts up Lucy Liu to spin her around and kick the thin man, to get Lucy's attention, Drew hollers out "Lucy!" even though Lucy Liu's character's name is "Alex." (00:26:20 - 00:27:25)
Revealing mistake: There are supposed to be two dead young Asian males sitting in the back of the car, but in this shot, it is so obvious that there are two dead 'dummies' riding in the back. Also, in the crash, a few seconds later, very blatant dummy heads are flying everywhere. (00:40:40)
Revealing mistake: After the final fight scene, where Maximus is dead and on his back in the sand, his armour would have made his head droop horribly backwards. To avoid that, the filming crew put a pillow of sand under his head to raise it about three inches. (02:20:10)
Revealing mistake: After Toad spits his slime at Jean Grey he falls to the floor. You can see the tether that was holding him in mid air. (01:13:55)
Revealing mistake: When Solina is crawling on the wall, whenever she turns her head, her long hair turns with it, instead of falling freely downward toward the floor. (01:05:20)
Revealing mistake: When Wick is rubbing his toeless feet, the shot changes so that the camera is behind him and you can see him still rubbing except now you can see that he is simply curling his toes over.
Revealing mistake: Just after Li Mu Bai tells Shu Lien that they are very close to her headquarters and that she should check in, we are treated to two 'time pass' shots of forest. The second of these features some very obvious power or telephone lines in the lower right corner of the screen. (01:22:40)
Revealing mistake: When Benjamin and Harry are talking on the steps of the legislature of Charlestown after deciding to go on war with the British, you can see a man behind them with something in his ear, a hearing aid or earpiece. (00:16:30)
Revealing mistake: During the scene on the beach just after the collision of the two bikes we see Scott and Cruise flying together in a big hug, but if you see the short shot when the black bike starts to explode frame by frame you will actually see a lonely man with his arms wide open.
Revealing mistake: When Memphis delivers Elanore to Calitri, he gets punched and falls to the ground. At his feet you see orange tape as stage markings. (01:38:15)
Revealing mistake: This mistake occurs in the beginning of the film where the bandits rob the train. When Jackie is standing on the coal (or was it wood?) car you can see the train is passing a modern sign (you can see it on the right).
Revealing mistake: Jennifer swipes her card the wrong way at the studio and the door opens anyway. (00:57:15)
Revealing mistake: The pastor knocks down a large wooden cross in his church with what sounds like a hollow Spalding ball. That cross must not be made of very sturdy stuff. Actually, it looks like the bottom of the cross was not affixed to anything. A stiff wind would have knocked it over. (00:54:22)
Revealing mistake: Many times throughout the movie, people are shot and they bleed, but their clothes don't have holes from where the bullets hit them. The most noticeable examples are when the teacher is shot at the end, and when the big gun fight between the girls breaks out in the lighthouse.
Revealing mistake: When Jonny is running away from Terl in the mall at the start of the film, he goes through several panes of glass, smashing through them. One of them breaks up before he hits it.
Revealing mistake: When Daniel is being chased along the rail tracks, both the Peugeot and the Mitsubishis' wheels change from road wheels to train wheels (with fake tyres on) and then back again when they move back onto the gravel. Clever cars... (01:11:05)
Revealing mistake: In the parking garage shoot out Arnold shoots the leg off a bad guy. While the bad guy is writhing in pain on the ground you can see his leg tucked back. (00:59:50)
Revealing mistake: Right at the beginning of the film when the crew walk down the tunnel from the shuttle to the space station, one on the left of screen bumps into the massive metal airlock door. It wobbles.
Revealing mistake: Throughout the entire film, whenever a character performs a high flying martial arts move, you can see that they are holding on to their wires.
Revealing mistake: When the U-571's crew member starts firing the MG-34 at the survivors in the rowboat, you can see the ammo belt is all blanks.
