Visible crew/equipment: After Glen sends the message, the soldier says, "Sir, I have authenticated air strike order from Sec Def.," In the next shot, just as Prime's silver bumper beneath the grille comes into view, the reflection of the crewmember who is standing on the filming vehicle's camera platform, beside the mounted camera, is visible on the right side. (01:49:30)
Revealing mistake: When Bonecrusher throws the car off the car-carrier, you can see that the underside is just a flat black-painted surface with no gas tank. (01:49:55)
Other mistake: During the chase scene on the highway, when Sam says, "It's the same cop," they pan to a wide shot to show the whole freeway with the cars on it. All of the vehicles are on the wrong side of the freeway. When looking out of the back of his car, you can see the fronts of all of the cars coming towards the camera, and you can see the text on the signs facing the camera as well. You can also see crowds on the flyover, watching the filming. (01:50:05)
Revealing mistake: When the bus splits after Bonecrusher smashes through it, you can see that it has no seats or passengers. (01:50:35)
Visible crew/equipment: In the aerial shot, as Starscream flies past the glass building with the names "Deloitte and Touche" (before his first attack on those in Mission City), we see the reflection of the filming helicopter behind Starscream, just beneath the names. (01:53:20)
Continuity mistake: When Bumblebee's legs are destroyed, as Sam leans over in front of him and asks if he's alright, Sam wears blue patterned boxers, but when Lennox runs up to Sam, who is standing on the tow truck helping Mikaela hoist Bumblebee, Sam's boxers are grey (as seen between his white tee and jeans). Then, when Sam is on the roof running, after the chopper is hit, his boxers are blue patterned. (01:53:45 - 01:57:10)
Revealing mistake: When Ironhide shouts, "Incoming!" as Starscream fires on them, Lennox and Epps are blown backwards and slam onto the ground. The shot of them hitting the ground and the next close-up of Lennox are flipped shots. Note the reversed 'Broadway Bar' sign and Lennox's watch. (01:53:45)
Continuity mistake: Odd how Mikaela is not wearing her stud earrings when Sam leaves her to go to Bumblebee and she spots the tow truck across the street, and also when she arrives in the tow truck and says, "Sam, help me with this." Yet, she is wearing them between those shots, when she breaks into the tow truck and hotwires it, and in the prior and following shots. (01:55:25 - 01:57:25)
Factual error: Mikaela hot wires the tow truck by twisting two conveniently exposed and very long wires together. Allowing that this could work at all in a modern vehicle, it can't steer until the ignition lock is turned or removed, neither of which she does. (01:55:55)
Continuity mistake: When Mikaela is telling Captain Lennox that she'll leave as soon as she gets Bumblebee out of the area, watch her hair. At first, her back is to the camera and her hair is perfectly smooth but when the camera is facing her, her hair is extremely messy. (01:57:55)
Continuity mistake: During the final battle, Sam and Mikaela tie Bumblebee down to the truck. When Mikaela says, "No matter what happens, I'm really glad I got in that car with you," Bumblebee is gone. (01:59:00)
Continuity mistake: After Sam takes off running with the All Spark, heading for the building, Prime is shown driving down the street towards a collection of garbage bins. In the next shot, before Prime hits them, all the garbage bins are set up very differently. (01:59:45)
Continuity mistake: When Optimus Prime first arrives in Mission City, he knocks over a few garbage cans, and a few pieces of paper gets stuck on the grill of the truck. But in the next shot, the pieces of paper are gone. This is not because he slowed down, because the grille is out of shot for less time then it would take paper to fall off. Not only that, but the air blowing at the paper would make sure it sticks on. (02:00:00)
Other mistake: When Optimus Prime comes powersliding into Mission City, take a close look at the ground. You can see skidmarks from previous attempts. (02:00:00)
Continuity mistake: After Megatron says to Optimus: ''Then you will die with them!'', Megatron throws Optimus away, and the latter one heavily damages a car, and two others skid sideways in order to brake in time. Two other cars remain parked. But in the shot where Optimus gets back up and draws his gun, only one car remains. Even if the two cars that stopped just before they hit Optimus drove away, there would still be two parked cars and one heavily damaged one. (02:01:00)
Continuity mistake: During the final battle, Sam rolls on the pavement and reverses direction as a jet-bot lands and transforms. The next wide shot shows Sam scurrying alongside the passenger-side fender of a black Mercedes sedan as another black car is tumbling over the Mercedes' hood, its doors wide open. This same moment repeats in the next shot, from another angle, but suddenly Sam isn't at the fender of the Mercedes- he has vanished. The angle changes again and the same moment repeats a 3rd time, and Sam is still missing. Then, a closeup shot is looking up past Sam as mayhem rages above, and the black Mercedes he huddles against is suddenly a red car. (02:01:20)
Revealing mistake: A yellow Pontiac GTO gets shot up, then gets blown in half with the rear end landing inside a shop window. If you look at the sideskirt of the car before it gets destroyed, you can see the cut already in the sideskirt where it will split apart. (02:01:20)
Visible crew/equipment: When Sam falls on the sidewalk with the cube and the machines start coming alive during the fight scene in the city, a fast shot shows a cameraman with the camera on the hands on the right side of the screen. (02:02:16)
Continuity mistake: When Mikaela has Bumblebee at the back of Mike's Towing truck, she drives down an alleyway, and when she stops the truck in the close-up there is a trashcan and other debris between the front two tires, which vanish in the wideshot. (02:02:25)
Visible crew/equipment: When Sam tries to hand off the All Spark, the chopper is shot down by Starscream. When the chopper wreckage flies over Sam lying on the ground, the black protective gear is visible between Sam's pants and tee shirt. (02:05:45)
Answer: Primus created the original Thirteen Transformers, later known as the Thirteen Primes, to help him defeat his nemesis, Unicron. The Thirteen Primes were the start of the Cybertronian race, which eventually turned on itself when Megatron, formerly Megatronus, started the War and his Decepticon faction.
