Continuity mistake: Carly's shoes appear to mysteriously alternate several times between black stiletto heels and black ballet flats in-between shots during the climactic action sequence. This is most noticeable during the collapsing building sequence as well as the scene in which Carly speaks to Megatron.
Continuity mistake: When Tony is in his garage injecting his arm, his chest piece is glowing brightly through his shirt, however, the very next shot when he is wiping his arm with the alcohol pad, his chest piece is suddenly turned off. (00:05:15)
Factual error: The location in DC has latitude and longitude both as N/S - longitude is an east/west factor. (00:13:05)
Revealing mistake: During the airport scene, after Tony tells Wanda that she hurt Vision's feelings, Tony and Hawkeye have their own banter moment. Then, when Hawkeye says, "Made you look," the next shot as the car is falling, Hawkeye is reversed; note his arm guard. (01:32:15)
Continuity mistake: After Peter gets the text from Happy about meeting at the bathroom, Michelle asks, "What are you hiding, Peter?" and just as she says, "I'm just kidding I don't care," Peter's holding his cell phone up in his left hand, but next shot he's holding the cell phone up in his right hand.
Visible crew/equipment: When the Protagonist passes through Sator's turnstile to return to the ambush site on the highway and gets in the inverted car, a cameraman holding the camera is reflected on the wing mirror. (01:31:38)
Revealing mistake: When Jack is hanging out of the truck you can see him standing on the hood of the car which Lydia is driving. At some points we get camera view from the back seat of the car. In some angles the mirror inside the car disappear. This is to prevent us from seeing the camera. (01:04:15)
Continuity mistake: When Mac's on the windshield and the car starts to dodge cars, one shot from inside the car shows the alien has disappeared.
Continuity mistake: Gambit pushes Logan, who smashes through a wall. This hole becomes much, much smaller when Gambit climbs out into the alley. (01:10:00)
Continuity mistake: When the young mutants are showing each other what they can do, they all have a glass of cola, all four sitting on a corner of the table. But when Banshee wants to show what he can do, the glasses are instantly lined up. (00:51:00)
Continuity mistake: Aquaman coughs up blood after he is stabbed by Wonder Woman. Some blood goes on his chin. Throughout the rest of this scene, the blood on his chin keeps going from the right side to the left side of his chin. (01:10:25)
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 K is cornered by the scavengers, he gets out of the car after they cut the door open. In the shot of one of the scavengers running up to K to attack him, nothing is hanging out of the car door. K then breaks the scavenger's back with his knee and the seat belt is suddenly hanging out of the door. (01:02:45)
Continuity mistake: Near the beginning of the movie, Milla Jovovich reads a note that has been left on the desk. She didn't write it, as they demonstrate in the film. However, when they do show the person who wrote the note composing it, the handwriting is different from that in the note from the earlier scene. (00:10:20 - 01:12:25)
Revealing mistake: The Thing takes a swing at the captain after the captain opens the door. As the Thing swings his arm, he takes out a chunk of wood out of the door. If you step through the frames on the DVD, you can see the wood leaving the door a full second after the Thing has hit it. A small explosive charge that was not in sync with the actor. You can also see the outline of where the wood comes off before he swings his arm. And one more thing, his arm does not touch the door or even comes close to where the wood comes off - a safety precaution I presume. (00:57:33)
Suggested correction: It is not a full second delay. It is four frames which translates to 1/6 of a second. Everything described in this entry is only visible if you step through frame by frame which invalidates the mistake.
Continuity mistake: In the scene where Arthur is lying in front of a bulldozer, he is so close that his hand is touching it. Two shots later he is a foot away from it, without appearing to have moved at all.
Continuity mistake: The poem displayed in Dr. Know's booth and the one on the door in Manhattan are slightly different. Dr. Know displays the line "waters and the wild" whereas the poem on the door read "waters of the wild." (01:26:30 - 01:34:10)
Revealing mistake: When the family's car is about to be hit by the ambulance as they try to escape downtown, Gerry is driving and his wife is up, leaning over the passenger seat talking to their daughter. The camera angle changes to a view from behind, and as the ambulance is about to hit, we can see there is nobody in the car and the ambulance driver is wearing a safety helmet. This is viewable in just a few frames. (00:08:00)
Visible crew/equipment: When the pilots are driving the plane and a spaceship pass them you can see a shadow of a microphone. (00:04:40)
Continuity mistake: As Mulder and Scully enter into the building that houses the bees is seems Mulder's tie gets blown over his right shoulder and then he is seen inside and it is over his left shoulder. (01:00:30)
