Visible crew/equipment: At Hoover Dam, after the salute, when Defense Secretary Keller speaks with Lennox and Epps, the reflection of the white reflector screen is visible on Keller's glasses. What's more, the boom mic's reflection is actually visible within the reflector screen's reflection. Two for the price of one. (01:35:30)
Continuity mistake: The Bank truck full stops away from a zebra crossing, but the close shot shows it on top of it.
Factual error: In a shot in Harlem, a Ford Econoline AVIS rental truck drives on the adjacent street. The specific Econoline van was at least a mid-90's to 2000+ model van and the movie takes place in the 70s.
Revealing mistake: When the Sergeant has the shotguns in the backpack on his back, and you see a close up of his face, you can see that the shotguns do not have triggers. On plastic prop rifles, the trigger is usually molded into the trigger guard in the pulled back position, and you can see this on these prop shotguns.
Continuity mistake: When McClane is driving the police down the ramp to the tunnel so he can elude the helicopter, the car's windshield doesn't have any bullet holes or cracks in it, even though it did just a few seconds earlier. (00:37:55)
Continuity mistake: At the mass hanging, when the singing begins, in one shot of the people (with the boy) standing at the gallows, the others down below, who wait at the head of the line, are also seen behind them singing. In a following shot, some at the head of the line differ.
Continuity mistake: The live news broadcast of Superman's interview after his resurrection shows it broad daylight in Metropolis. When Martha Kent sees this at her farm, although being in the same state, it is pitch black night time outside at her house. (00:40:10)
Continuity mistake: When Memphis is tortured, he gets water poured in his mouth from a bottle. When they're done pouring, the water level in the bottle is almost full. (01:07:00)
Suggested correction: Before this frame, there is a shot showing multiple water bottles on a nearby table... it could easily have been the next bottle of water?
No, it could not because the shot was meant to be continuous. After Memphis spits out the water, we see the guy holding a half filled bottle start pouring water into Memphis' mouth. When the camera angle changes (i.e. continuous shot and not a jump cut), we still see the guy holding the bottle up to Memphis' mouth. It's at that point the bottle has changed and is now almost full.
It's even worse than that. It refills at least twice between those quick successive shots.
Continuity mistake: The left tail light of Sadie's car is broken when she picks up the unfortunate hitchhiker. The light works when she turns left off the road. (00:36:20 - 00:38:35)
Plot hole: In the scene where 47 swings out of the hotel window, we see the booby trap starting to explode as he's still in the room. Then in the shot from outside, the explosion extends out the window - so how on Earth did he outrun it and get out completely unscathed?
Visible crew/equipment: When Torch is in the Black Forest, watching the crystal ball, 4 big light screens are reflected on it.
Plot hole: When the survivors arrive in Las Vegas, all that is visible is the Strip. No other buildings are seen, even though Las Vegas has other high-rise buildings that are not on the Strip, and the level of sand that has built up is not substantial enough to have buried the entire city. (00:55:00)
Continuity mistake: At the end of the movie as Michael Clayton is hailing a taxi, there is a silver SUV and a moving truck behind the taxi. As he gets into the taxi, the SUV and truck disappear and there are only yellow taxis behind his own. (01:53:30)
Continuity mistake: When Stuntman Mike is eating and talking to the blonde girl in the bar, he is holding a glass of club soda. When the shot reverses, he is wiping his hands, then when the shot returns, he is holding the club soda again.
Continuity mistake: In Madrid Bourne calls the emergency line and says he's in 334 Norte street, which triggers cops to show up. When Bourne arrived at the building he looked at the door and it was a 2 digit number which one can faintly see it starts with a 1. (The filming location took place at number 10 Virgen de los Peligros street).
Continuity mistake: Shoeshine is telling Jack to 'give the dog your food'. Jack throws him a rubber steak, which moves further away from Shoeshine in a subsequent shot. (00:35:00)
