Continuity: During the chase scene, where Bonecrusher and Barricade are chasing the Autobots on the highway, Bonecrusher transforms into robot mode and is shown skating across a 6 lane highway. Optimus Prime is shown to transform into his robot form to fight Bonecrusher. You can see the 6 lane highway in front of Prime stretch on as far as the eye can see, and there are no ramps or overpasses anywhere in sight. Yet at the moment of impact, when Bonecrusher tackles Prime, they are suddenly on a highway overpass, which they fall off of, and fall onto ANOTHER highway overpass. Submitted by wizard_of_gore

Continuity: When one of the robots pull Sam's pants off, when they first meet Bumblebee, he's wearing boxers with some kind of design on them. Later, Sam is bending over the Hoover dam, and he is very noticeably wearing different underwear, yet he has had no time whatsoever to change them; even if he did, [which he doesn't] why wouldn't he change his clothes also?

Other: During the last fight, Megatron and Optimus Prime flies through an office building while locked in combat. It is shown that the interior of this building is filled with both people and furniture, but when they crash through the last wall, only building debris fall to the ground with them. No people, furniture, office supplies, papers or any of the things that the building was full of. Submitted by Twotall

Continuity: When Jazz uses his magnetic hand to remove some of the guns from the Sector 7 people, the guns fly into his palm, but in the next shot, his hand is down and there are no guns in his hand or on the ground. He couldn't have put his hand down or throw the guns away that fast between the shots.

Continuity: When the Autobots arrive at Sam's house, we only see Optimus, Jazz, and Bumblebee driving up to the house. But when they transform, Ironhide and Ratchet have appeared and Jazz is nowhere to be seen. Later, Jazz appears from nowhere. Also, when Sector 7 arrives, the Autobots are gone without a trace.

Other: In the scene where Sam and Mikaela are parked at the top of a cliff after "breaking down", Mikaela lifts the Bonnet of Bumblebee to check the engine. Mikaela, who's the car expert, states the motor has a carburetor, yet the manifold on the engine was one for a direct injection motor.

Continuity: When you first see the comets with the transformers in them fall Sam and Mikaela are in front of the white house. When they start to holds hands notice the change between the length between their shoulders and upper body between the front shot and back shot. Submitted by R S Handfield-Jones

Revealing: When Sam Witwicky's great-grandfather activates Megatron's navigation system, he is blown back. As he falls, you can see one of Megatron's robotic fingers wiggle.

Factual error: Why does an Air Force base have so many Army vehicles? Particularly M-60 Patton tanks with M109A6 Paladins that aren't currently in service?

Factual error: At 51:00, the Transformer asks Sam if he is "username ladiesman217" and "where is EBay item 21153". However, it is impossible for an item sold so recently to be that item number. If you sell an item now, it would be over item number 200000000000.
