Revealing mistake: In the highway chase scene, when Crowbar knocks down some signs for the other two Dreads to use them as ramps, the simple structure supporting the signs changes to a far more elaborated one when the Decepticons launch from it. The signs are even replaced with actual platforms, much longer, wider, and with different angle and separation than in the previous shot.
Revealing mistake: Right after Sentinel finishes his speech at the tower, there is a shot where a lot of ships are shooting at buildings, but when they smoke from the explosions is gone, none of them is damaged. This mistake can also be seen when the dropped US soldiers are being chased and shot at by Decepticon ships.eructo666
Revealing mistake: Toward the end, when Sam is going to destroy the tower he gets kicked in the stomach by Dylan. When Sam falls he lands on another part of the destroyed building, you see the chunk of building that he lands on conforms to his body, showing that it is made of foam to soften his landing.
Revealing mistake: During the highway scene with the black GMC Decepticons chasing the Autobots, a number of civilian cars are flipped. If you look at the underside of a few of the cars, you can see the hole they use to launch a post to help flip the vehicle for the stunt. A brief puff of white smoke can also be seen on a Toyota Camry which is from the CO2 used to launch the post during the flip.jerimiah
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
Revealing mistake: During the highway chase scenes there are two "out of sync" animation sequences of the Decepticons in action.1) In the front view with all the cars facing the camera, the Decepticon robot on the right shoves the car sideways (to the right), however, the car flies into the air a second later and in the opposite direction.2) The scene cuts to the side view of the Decepticon and you see him motioning to pick up a car and begin to toss it in the air. However, when he does this, his hand is empty and the car just flies just below him.
