Continuity mistake: When Agent Simmons takes Mikaela and Sam into custody, the headrests in the SUV vanish when Prime shows up. The driver's headrest is visible just after they enter the car. When Sam says, "My car had been stolen, from me, from my home," and when Simmons asks, "What do you kids know about aliens?" the headrest behind Sam is visible, among other moments. (01:19:00)
22nd Apr 2009
Visible crew/equipment: After the agents are handcuffed, when the Autobots transform into their respective vehicle modes as one of them says, "Roll out!", there are three black ramps positioned in front of the sidewalk, which were not there before. The Autobots use them when driving up onto the sidewalk. (01:24:20)
22nd Apr 2009
Continuity mistake: After Mikaela and Sam walk away from all the handcuffed agents, when we hear an Autobots shout, "Optimus! Incoming!" the railroad crossing post is visible behind the Autobots, but Agent Simmons is not handcuffed to it. Then, when we hear, "Roll out!" Agent Simmons is handcuffed to that post as he should be. (01:24:20)
22nd Apr 2009
Continuity mistake: Mikaela begins cuffing the undershirt/boxer wearing Agent Simmons arms around a post in the wideshot, then it cuts to the close-up, as she handcuffs the dark suit wearing right wrist of one agent to the dark suit wearing left wrist of another agent. Then in the two following shots we see that she and Sam have actually just cuffed the undressed Agent Simmons left wrist to the dark suit wearing second agent. (01:24:00)

21st Apr 2009
Continuity mistake: When Sam, who is wearing boxers, is running from away Frenzy there is a large tear on his left sleeve, at the elbow. When Sam reaches the fence Frenzy attacks him, and as Sam covers his head with his arms we see the tear is gone from his left sleeve (viewer's right). (00:54:05)
21st Apr 2009
Visible crew/equipment: As Barricade and Bumblebee are fighting, when Frenzy attacks Sam and pulls off his pants, the padded black knee guard (with a white stripe at the top and bottom) that Sam wears on his right leg is visible when he is lying on his back, just after he shouts, "He's gonna kill me!" It's gone in the previous and following shots. (00:53:50)
21st Apr 2009
Visible crew/equipment: After Bumblebee locks its doors with Mikaela and Sam inside, the Camaro speeds past Barricade and does a 180° spin. Just before the shot cuts away, as the passenger door first opens there is a perfect view of the back right tire, where we can see the stunt cable attached to under the tire. (00:52:50)
21st Apr 2009
Visible crew/equipment: After Sam is interrogated by Barricade, when Sam knocks Mikaela off her moped the black protective gear that Mikaela wears is visible. It is gone when she gets in the car with Sam. (00:51:05)

21st Apr 2009
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)
21st Apr 2009
Continuity mistake: When Sam is being chased by Barricade, he is thrown on the windshield of a car and then mutters about it being a bad dream. In the next shot, a wheel and other junk has suddenly appeared on the car's roof. (00:50:35)
21st Apr 2009
Continuity mistake: After Sam is knocked off the pink bike, he ends up on the ground as Barricade, aka the police cruiser, drives forward causing Sam to keep backing up, which leaves the bike near the back of the cruiser. Yet, when Barricade threatens Sam with its weapons, the bike is right beside the cruiser's front end again. (00:49:35)
21st Apr 2009
Continuity mistake: When Maggie arrives at Glen's house, in the shot facing him as he shouts at his grandmother, Maggie's open empty right hand is up just as it cuts to the next shot, but now her compact is in her right hand. (00:45:45)
21st Apr 2009
Continuity mistake: At the Pentagon, when Maggie is sitting with her team of 'experts' and one suggests Iran, in the shot facing Maggie's back her file folder is closed and lying on the table in front of her, but in the next shot, she closes the open folder. Between these two shots, the analyst to her right goes from holding his headset by his ear, to holding a pen on the book in front of him. (00:27:50)
21st Apr 2009
Continuity mistake: During Sam's family genealogy report, when he holds up Captain Witwicky's glasses to show the class, there are cracks in certain areas of both lenses. Those cracks actually change position and characteristics when we see the glasses elsewhere in the film, such as on eBay and when Prime explains their importance to Sam and Mikaela when they first meet. (00:10:15 - 00:17:40)
21st Apr 2009
Visible crew/equipment: When Sam rushes to his waiting father after class and tells him about the A- they drive off. In the next close-up shot the filming vehicle, with its top mounted crane and camera at its front end, are reflected on the car's surface as they drive past, before pulling into the Porsche lot. As this shot continues, when they drive onto the Porsche lot, the filming vehicle directly behind them (note its headlights), is reflected on the large windows in front of them and when Sam is told he isn't really getting a Porsche the filming vehicle, which is now beside them, is reflected on the window to their left.
