Continuity mistake: After Stark is paralysed and slightly recovers, he goes to get his energy. Right then the blood around his left ear has vanished. Being seconds away from dying, the last thing he would think of is taking a shower.
Continuity mistake: When Nicolas Cage drives through the window in the yellow Ferrari and the shot changes, he is coming out from a different window than in the first shot. In the first shot he emerges from the window to the left of the 7th Street Garage storefront ('Classic Autos' written on the window), but next shot he emerges from the window to the storefront's right. Also, note the now glassless window to the storefront's left, due to a previous take.
Continuity mistake: When the girls figure out that Knox is after Charlie, and Dylan thinks of the picture and they zoom in onto "Townsend." The shot before the final shot of the photograph shows Knox's father's arm around Charlie, when in all the other shots, he has his arms above his head. (01:00:05)
Visible crew/equipment: Just after Lockdown stabs Optimus in the chest with his own sword, Cade runs closer and shoots at Lockdown. He then hides behind some bricks. In that shot, the bricks are a broken wall that is two separate pieces. Then it cuts to a different shot as Lockdown returns fire at Cade, and now the wall is one piece. Not only this, but some random guy suddenly appears in the shot next to the wall and right where the explosion happens where Lockdown shot the wall. He is wearing the same color clothes as the wall and only visible for a moment. There was no other guy present until that moment and he just suddenly appears behind Cade and gets hit. It's presumably a special effects member setting off the charge in the wall by the looks of it and it detonated before he got out of the shot. (02:30:55)
Continuity mistake: When Snake kills the wrestler he falls forward shoulders forward, next minute his arms are over the ropes, next minute his arms are in a different position again - quite active for a dead man. (01:16:55 - 01:18:10)
Continuity mistake: After the Bandit jumps the bridge Sheriff Justice rear-ends the cop car in front of him, smashing the hood of his car. In the next scene Sheriff Justice's hood is fine.
Visible crew/equipment: After Indy and Henry have escaped from Castle Brunwald, Indy jumps into one of the boats, pulls the motor starter cord and jumps back out, then just as he bends over to release the boat from the piling, right between Indy's legs the black covered arm of a hidden crewmember appears from under the tarp taking hold of the throttle, steering the boat away from the pier. (01:02:40)
Continuity mistake: When the statue of Liberty is about to crash on the street, a close shot is seen of jammed cars and hysterical people. When the shot changes to Superman flying to the rescue, the jam, the cops and the people have disappeared, and all is nice and quiet in Metropolis.
Revealing mistake: There's one scene where they are surrounded by the foot. Leonardo reaches behind him for his katanas, but he doesn't unsheath them. If you look at his elbows, you can see gaps in the pads where the actor in the suit hasn't fully fastened the gloves to the rest of the outfit. (01:05:40)
Revealing mistake: When Batman brings the Penguin to the Batcave the Batmobile skids to a stop on the gray floor. It then begins to rotate in the next shot and it's now on a black platform. When the Penguin emerges from the car and walks toward the rear of it, the platform is obviously gone. (01:06:10)
Visible crew/equipment: When Benedict snaps his fingers and the dogs form a pyramid to show how well they are trained - look at the dog's feet and you can see the rails that the dogs are standing on. (00:43:50)
Visible crew/equipment: During the "full attack" at the start of the Battle of Stirling Bridge, Wallace repeatedly shouts, "Hold," and in the wideshot right before Wallace finally shouts, "Now!" as the horses gallop towards the right side of the screen, we can see a white car at the left side of the screen. Viewed widescreen version. (01:27:15)
Continuity mistake: When Nick is singing "Spend This Night with Me", he brings up a girl from the audience. Watch the background. When it shows another girl from the audience, in the next shot, you can see a speaker that wasn't there before. Moreover, when he picks the girl, we can see that there isn't anyone at her left side. But a few seconds earlier she was sitting between two girls (the one at her left was wearing a white shirt). (00:42:05)
Continuity mistake: When Indy is distracted by the young girl and her eyelid message, the girl changes from a window seat to another row when the bell rings to end class.
Visible crew/equipment: Near the end of the movie when the convoy is heading back to the Pakistan Stadium, a Humvee stops briefly to allow a man to walk across the street with a child in his arms. When the shot changes and the Humvee begins driving again, a crew member or cameraman is seen inside the Humvee wearing a white shirt. All of the men who entered the Humvee were wearing fatigues. (02:05:27)
Visible crew/equipment: Black support rods are visible on both of the "standing" skeletons, which are holding the medallion that Juni steals. The rods are by the skeleton's right leg bones, and are not bones. (01:09:25)
Continuity mistake: When they bring Marvin Nash to be tortured, his hands are cuffed behind his back. They start kicking him and his hands are then seen cuffed in front. Then, they switch back just a few moments later and his hands are back behind his back again.
Continuity mistake: There are a couple of instances in the movie where the models do not correspond with the actual sets. When Klytus arrives at the Hawkmen city he lands near the top of the city. Yet in that very hall there is a pit with a deep void underneath. Such a room could only exist at the bottom of the city. Also, when the Hawkmen start to land on Ajax, its engine section appears to be missing. (01:10:10 - 01:14:30)
Continuity mistake: At Tia Dalma's, when Jack says, "Look, an undead monkey," and shoots the monkey, the flame of the candle above the monkey is extinguished from the gunfire. However, in the next shot that candle is burning brightly.
Continuity mistake: When Tyler gets beaten up by Lou, his mouth is bleeding after the first punch. After maybe two punches Tyler jokingly claims to "get it", then he says he "lost it". Right then the blood is no longer there. (01:12:25)
