Continuity mistake: Roy is on his back at one point, seemingly knocked out. A shot later he's suddenly on his stomach before regaining consciousness.
Revealing mistake: Crawling through a fire cave you can see propane bottles in the background several times.
Revealing mistake: In the news reel detailing the Kohinoor theft, a few headlines appear, and at least one persists on screen long enough to easily spot the inconsistency between headline and article (filler text presenting a new local magazine from the London district of Lambeth). (00:09:00)
Revealing mistake: JR is in the weapon container of the crazy dealer, who passes him some of his goods. JR ends up holding in his right arm a MP5K and an M4A1, which combined are about 5 kilos, but then he passes him an M60 Machine Gun, which weighs over 10 kilos and that the relatively diminutive protagonist just handles throughout the scene gripping it with his left hand and making no effort whatsoever. (00:25:20)
Continuity mistake: When the kids are looking at the Stonehenge-type structures, the younger boy calls for everybody to come and see the hidden message. From the shot in front of the boy you can tell from his body position he's sitting up, however in the next shot from overhead, the boy is now lying down on the rock.
Factual error: The newsreel at the start of the movie shows a carrier preparing to launch aircraft. The announcer claims it is the Enterprise, but in actuality, it is either the Lexington or the Saratoga, evidenced by the huge funnel.
Audio problem: The one-eyed warrior who drags the prince inside the inn says "Look who I found skulking outside", but his mouth does not open. (00:21:40)
Revealing mistake: Jim parts his hair on the left side. The stacks of his books on display in the hallway include a photo of him with his hair parted on the right side, but otherwise looking the same. Hair that is persistently parted on one side will not easily part on the other side and lay across the head in the same way. (The image was reversed). (00:25:20)
Continuity mistake: When Paul steals the Camaro, he pulls wires out from under the dash to hot wire it. But after he gets his daughter he suddenly has keys.
Continuity mistake: In a scene at a night club, Colin Firth's friend has a glass of red wine in his hand and then he has a glass of white wine.
Continuity mistake: During the scene of the first meeting between Gus and Ruby, Krysten Ritter's hair moves back and forth (behind or in front of her left shoulder) between shots multiple times (most obvious example: when he offers her a drink). (00:12:45 - 00:14:35)
Factual error: The alien drops the video camera out of the UFO from outer space and it falls to earth landing on the ground. This very far drop would certainly have busted it to pieces, if not ignited it on reentry, but when the guy picks it up off the ground, it appears only the screen is cracked.
Continuity mistake: Everly opens the surprise as instructed, and tosses away in horror the lid of the gift box. The lid falls off the armchair, and yet a few seconds later, with nobody else alive in the room and the protagonist that never stopped freaking out on her knees, someone picked it up and it sits by the box. (00:09:30)
Factual error: When the Germans come to the town a tank rolls through the picture. The first shot shows the tracks, then the whole tank is shown and one can see the tracks again. The turret suggests a Panzer III (which would be accurate for the time). It appears however that the tank is a modified Russian T34 or T55 or something as the road wheels are too big for a Panzer III. (00:13:00)
Continuity mistake: Judge Pendergast calls the daughter of his therapist, who reacts with typical New York aplomb. During the scene, the same extras continue to walk back and forth with no logic, sometimes coming twice from the same direction, even. Most egregious example the blonde with a ponytail and sunglasses on top of her head. She is behind Jennifer Aniston in the opening shot and appears at least 4 times (possibly more but there's another blonde too -unless it's the same one who occasionally removed the glasses) and walks away from Aniston and Forte two times in a row. (00:17:40)
Continuity mistake: As the jeep with the killer goes over the cliff and smashes face down you can see nobody is in the jeep as it disintegrates the front part. (01:14:00)
Continuity mistake: The students' 3rd game is Kagome with 4 Kokeshi dolls. The pink doll starts to the right of the first student to play, the dolls move in a circle around him, she passes in front of him and by the end of the shot she is near his left. The Kokeshi dolls all move backwards between shots and the pink doll passes in front of the student again. After this, she takes 7 seconds to move about 100° despite nobody slowing down and she took that amount of time to move about 170°.
Continuity mistake: As the two assistant workers walk away from the prison building at the end of the first day, Charlotte Gainsbourg's grip on her folders switches between shots.
Revealing mistake: Most of the tank battle scenes throughout the movie are low budget CGI.
Continuity mistake: In the "Another Brick in the Wall Part III" section of the show, look at the missing section of the wall on the right hand side. The bottom bricks of that section change from being filled in to being empty depending on the shot. (01:02:40 - 01:04:00)
