Other mistake: At the end of the song "Wait," when Sweeney and Lovett hear Anthony running up the stairs, Sweeney runs behind the door to his shop. For a quarter second, as Sweeney places his back against the wall, there is a modern-day water bottle on the window ledge. This, however, cannot be seen on the DVD or Xbox, though on laptops and probably computers also, when streaming you can see it around 00:43:10. (00:43:10)
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.
Continuity mistake: In the scene where Dakota is having sex with Aubrey's boyfriend, it specifically shows that her bra is off. Once they finish, and she is getting off of him, she is covering her chest with the sheet. When she does this, her side isn't covered and you can that she is now wearing a black bra.
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: When Ro eats the tub of ice cream, the way it faces and the amount in the tub continues to differ.
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: At the end of the film, Victor tells Nick to write 'hey Annie' on plane's wing to send her a message. When Nick throws the plane and the camera shows it flying around, the words that Nick wrote are nowhere to be seen.
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?
Continuity mistake: When Rigg is watching the tapes of Jill's interview he picks up a guide to civil engineering book. Camera does an instant cut and now he's got a police file in his hand. (00:15:30)
Continuity mistake: During the final chase scene, as Stuntman Mike started for a while to dab the girls' car, in a scene the shadows of the cars change size between one shot and another.
Character mistake: When Mr. Brooks and Marshall hack into the police database and are looking at detective Tracy Atwood's financial records there is a screenshot of the computer screen showing some very terrible spelling.
Continuity mistake: Anna brings Semyon only copies of the original diary. The sheets are held together by handbag clips, which are closed in the close-ups, and open in the views from her angle. (00:23:00)
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)
