Continuity mistake: When the Decepticon jumps into the leaning building, Carly ducks in panic. When the shot cuts, she is standing straight up again, very calm at that.

Factual error: Big Joe has an AT-4 rocket launcher, which gets loaded before he wants to shoot the pillar. AT-4's are not reloadable.

Continuity mistake: When the soldiers are wingsuiting into Chicago, they fly past Trump Tower multiple times.

Friso94

Continuity mistake: When Starscream flies in to destroy the Ospreys with Lennox and his team, you can see that the streets below are pretty badly damaged. When the soldiers jump, there are a few shots from a helmet cam from one of the soldiers and the streets are completely intact.

Continuity mistake: During the Mexican Standoff, Ironhide finally forces the spike into the face of one of the Dreads and lifts him up by it. Pay attention to the red car underneath: when Ironhide smashes the Decepticon's face, the windshield is fine, but when he puts him down, the windshield is suddenly damaged - before the Decepticon lands.

Trivia: Remember Sideways, the Audi R8 Decepticon Sideswipe sliced in half in the opening scene of Revenge of the Fallen? Well, he has a cameo, in which his fate is no more fortunate than it was last time around: he is the one who Optimus Prime stabs in the chest and swings around during the Rage.

Friso94

Revealing mistake: During Optimus Prime's rage the same red BMW gets flipped three times.

Visible crew/equipment: In the shot of Optimus driving along with the Driller, part of a camera mount can be seen in the reflection of Optimus' chrome grille. It's definitely not something next to the road, since it's moving at the same speed. (00:18:25)

Friso94

Continuity mistake: Just before the soldiers jump out of the Osprey, there is a shot of them running for the exit. You can see a very big gun on the soldier's chest. But in every shot of them wingsuiting through Chicago, none of the soldiers can be seen carrying any kind of weapons, let alone big LMG's and assault rifles which they use after landing.

Continuity mistake: *Spoilers* After Optimus rips Megatron's head and spine out, he drops it right next to Megatron's dead body. But when Sam and Carly are reunited, the head with the axe lodged in it are much further away from Megatron. (02:23:00 - 02:24:35)

Continuity mistake: When The Ark escapes Cybertron it is hit by a missile tearing off a massive chunk out of one of its wings. Yet when it crashes on the moon, both wings are fully intact.

Friso94

Visible crew/equipment: In the first overhead shot of the Autobots entering Chicago, you can see a small black camera cart in front of Bumblebee and Mirage. (01:47:45)

Friso94

Continuity mistake: When Optimus takes a dive after his rampage in front of Shockwave, you can see that it is actually in front of the building with the control pillar in it (note the very distinct clock in the background) yet when Optimus shoots the dome and the pillar down, he's a good distance away from it.

Friso94

Continuity mistake: When they all slide down the building, we get a shot that pans up. In this shot, Sam is the one closest to the bottom of the building and Carly is one of the people on the very top. Yet in the next shot, Sam catches up with Carly. (01:55:45)

Continuity mistake: Sideswipe's rims keep changing throughout the movie. At some point he has rims which have a pretty big distance between the edge and the actual spokes and at other points he has rims which have the spokes on the edge of the wheels all together.

Friso94

Continuity mistake: When The Xantium leaves earth, it leaves a massive trail of smoke. When Sam calls Dylan, the smoke is gone only to reappear after Starscream blew the Xantium up.

Friso94

Revealing mistake: When Optimus has his 'rage' on Wacker Drive, you can see that cars that are being flipped not entirely by volition, since some of them (most notably the red BMW before he cuts a Decepticon clean in half) aren't even touched by Optimus or any Decepticons. (02:15:15)

Friso94

Factual error: Cybertron is placed between Earth and the Sun, as you can see in the shots from outer space. But it doesn't see to block the sunlight, despite being notably bigger than the Earth. It may be a framework but it's very dense with multiple layers.

Friso94

Continuity mistake: After Ironhide crashes into the remaining Dreads, we see that Crowbar lands on a bus stop, but when Sideswipe arrives, he is in front of an open garage door, at least 10 ft. away from the bus stop, debris is nowhere to be seen. (01:09:00)

Friso94

Continuity mistake: When NEST is tracking The Dreads, in the satellite shot there is hardly any traffic on the freeway. However, in the shot immediately afterwards, it's very busy.
