Other mistake: So let me get this straight: Optimus Prime has Energon Swords hidden in both of his arms, with which he can slice through an entire Decepticon in one chop, yet when he is hanging from a few wires, despite having one arm entirely free, he can't cut himself loose?
Other mistake: The knife used in the Argentina pub scene never has any blood on it, despite being driven into one man's stomach and another man's hand-twice.
Other mistake: Will did not have enough time to place into the pot at the poker game. For those at the end of a hand, they each have contributed a minimum of an equal percent based on the number of people in the hand. There were potentially 5 people at the start of the hand, and Will did not have enough to cover 20% of the final pot. He would have needed well over 200 years available, and we know he had a little over 100.
Other mistake: When David Norris is first trained in using the doors he is told to turn the handle clockwise yet one of the first doors he uses is a "push bar" door that can't be turned at all.
Other mistake: When the conductor / ticket inspector is checking tickets, why doesn't he check Christina's?
Other mistake: When Graeme is convincing Ruth to go with them and she says "Where would I sleep?", you can see her left eyeball through the dark lens: it moves as she looks to her right twice and then back. In the next scene, it is shown that she doesn't have a visible eyeball in her left eye. (00:45:05)
Other mistake: The Super 8 cameras used are both sound models, one Eumig and one Kodak, but when the film and film boxes are shown, they are the normal Super 8 silent cartridges, which are square. Sound movie cartridges are rectangular to accommodate the sound recording mechanism in a Super 8 Sound camera. (00:15:55)
Other mistake: In the scene where they are all running down the stairs of the tower and going into their houses to get their weapons, Moses goes to the lowest floor of them all. Near the end of the film Moses tells Sam to go one floor down to go to his flat which can't be right as he went several floors down to his flat earlier.
Other mistake: Charge kicks down the door of the room Rickshaw is in, and is just a few feet away from him, directly in front of Rickshaw. It makes a very loud noise as the door breaks. Yet Rickshaw does not notice at all until Charge walks in a few steps. (01:09:50)
Other mistake: When priest is getting ready to leave the city we see him wrapping his hands in his black shirt but moments later when he pulls up his hood his hands are bare.
Other mistake: When Schmidt sets the self-destruct timer at the Hydra base, the clocks count down at twice the speed of real-time.
Other mistake: When the captive begins her escape, she kicks the bed through the orange portal offscreen, but the portal only starts about a foot off the ground, so the bed would have hit the wall, rather than have gone through the portal.
Other mistake: Between the freeway battle scene and the convenience store scene; there's a transition shot where you can see the characters walking through a bombed out LA with the alien aircraft flying above. If you pay attention to them, instead of following the camera, at the end of the shot you will see them all stop moving mid-stride while everything else in the shot continues to move.
Other mistake: Just as the preacher finishes stitching up Jake's wound, a shot rings out from the street, and everyone goes outside to find Percy Dollarhyde drunk and shooting up the town. Percy is right-handed but holsters his 6-shooter revolver on the left, and this appears to be his only sidearm. Even if he did carry another 6-shooter, that wouldn't explain how he fires 13 shots in this scene without reloading.
Other mistake: Towards the end during the last fight with Zeus, Atom is following Charlie as a mirror - when Charlie moves his right hand Atom moves its left, etc.. At one point in the last round Charlie jumps and punches with his right hand, but Atom hits Zeus with its right too.
