Continuity: In the junkyard when Bumblebee is trying to get away form the "cop", after Bumblebee locks the doors with Sam and Mikaela inside, the windows continually change from being up and down.

Visible crew/equipment: When Sam is talking to Mikaela's boyfriend, you can see the camera and crew reflected in the Hummers mirrors.

Visible crew/equipment: When Scorponok is damaged by the 105-shells in Qatar, as the camera is moving behind the soldiers, you can see the camera shadow moving on the wall to the left of the screen.

Revealing: At night, when Sam's car is running away by itself, you can see out of the windows that it was filmed in broad daylight.

Visible crew/equipment: When Sam and his friend head for the party at the lake, as they drive by the lake and the camera cranes up to show the lake, you can blatantly see the shadow of the camera on the crane moving up.

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.

Continuity: 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.

Continuity: When Bumblebee "breaks down" on the side of the road, a book appears in Sam's hand that wasn't there before.

Revealing: When Sam flips over on the bike, in one shot you can see that it is a stuntman who looks much older than Sam.

Revealing: When Blackout is destroying the base in Qatar, a few Humvees get flipped over, and none of them have engines in them.

Continuity: When Mikela hotwires the tow truck, it has an automatic gearshift. Later, when she is driving and Bumblebee is shooting, look closely, it's now a manual transmission.

Visible crew/equipment: When Banachek and Simmons are talking to Sam at the entrance of the Hoover Dam, you can see the white lighting panels reflected in their sunglasses.

Deliberate "mistake": If you pay extremely close attention to the scene of all of the Deceptacons responding to the small Transformer's message regarding the location of the Allspark, notice that the shot of the police car and the fake helicopter pilot are duplicate shots used earlier in the film.

Continuity: 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.

Revealing: In the final battle, Captain Lennox is going to shoot Blackout. He gets on a motorcycle, goes really fast, and then slides off the bike and down the street. While he is sliding, he shoots Blackout. When Lennox gets to his feet, you can see his back, and his shirt is not worn away at all. It isn't even discolored.

Other: When Mikaela and Sam are in his car when he gives her a ride from the lake, both windows are open but her hair doesn't blow around at all - like it would if they were really open.

Visible crew/equipment: During the opening shot of chapter 19 on the DVD the camera pans to the front of Optimus Prime. The camera truck/operator is reflected on the right side of the bumper.

Continuity: When Josh Duhamel's wife is watching the broadcast saying that everyone at Qatar was killed, the door is wide open. When she sits down to feed her baby, the door is now closed and the high chair has been moved accordingly.

Continuity: When Bumblebee is captured by Sector Seven, the camera goes back to Optimus Prime talking to Mikaela and Sam. If you look at her hair, it is loose and flowing. In the next shots when Sector Seven capture them, Mikaelas hair is tied up at the back, she had no time to tie it up.

Visible crew/equipment: When the soldiers discovers the telephone line in Qatar, Scorponok tears down the tower. As the tower hits the ground we get a frontal view of the soldier wearing glasses. As the soldier turns his head we can see the film crew reflected in his glasses.
