At the end of the movie Secretary of Defense Keller says the remains of the Decepticons have been dropped into the Laurentian Abyss and identifies it as the 'deepest place on the planet'. In fact, the deepest place on earth is 'The Challenger Deep' in the Marianas Trench - 35,838 feet below sea level. The Laurentian Abyss is a gouge, by comparison, at 19,685 feet at its deepest section. In fact the Laurentian Abyss is not even the deepest in the Atlantic Ocean [The Marianas Trench is in the Pacific]. Deepest in the Atlantic is The Puero Rico Trench, at 27,651.
When the soldiers are fighting the Scorponok, one soldier is on the phone trying to call the Pentagon, when he leaves the house searching for a credit card, he yells a lot of things, but his mouth movements does not match what he is saying.
When Captain Lennox is trying to contact the Pentagon during the fight with the scorpion thing in Qatar. He is on the phone with the operator and when he yells "I'm in the middle of a war-zone, this is frigging ridiculous." The words do not match what he actually says.
When the A-10 uses its 30mm cannon for strafing in the Qatar desert, the sound has absolutely nothing to do with the actual sound of a GAU-8 cannon firing. The real sound is more of a growl, sort of the sound of a vibrating cell phone on a hard surface.
During the battle in the city, Captain Lennox picks up an Aprilia RSV-Mille. Then the soundtrack reveals the high-pitch whine of a high-revving four-cylinder. In actual fact, the Aprilia is a V-Twin which would produce more of a low, thumping, two-cylinder sound.
Just after Barricade assaults Sam regarding the glasses, Bumblebee drives by, trips Barricade, then swings around and opens his passenger door to pick up Sam and Mikaela. For a brief moment as the door starts to open (and when it later closes), one can hear the distinctive buzz of a solenoid operating on 60 Hz AC power.
While in NBE1's (Megatron's) chamber, Simmons has a flag patch on his vest that is improperly worn. He has it on the right side of his chest and the union is facing away from his heart. When wearing a flag, the union must be placed nearest the heart and since Simmons has the patch on his right side, it should be a 'reversed field' flag patch that faces his heart, while he wears a 'left' flag on his right side that faces his arm. Typically, when wearing one flag patch, it should be worn on the left side of the body and is recommended that is be worn on the sleeve.
Agent Simmons tells Sam about the loss of the "NASA mission Beagle II to Mars" which managed to send back an image of something on the surface before being destroyed. Beagle II was an ESA (European Space Agency) mission, not NASA, was intended to be a lander, not a rover. The images from Mars were based on the Mars Exploration Rover missions (Spirit and Opportunity) which do not resembled the Beagle II spacecraft at all. However, Simmons is elsewhere shown to have an extremely poor knowledge of where things come from.
Throughout the film, Qatar is pronounced with the emphasis on the second syllable. DoD employees would know the proper pronunciation stresses the first. CAU-ter is the closest, though English lacks an equivalent to the original Arabic, especially the peninsular dialect.
Day into night - twice during action shots (first at the SOCCENT base, later for Bumblebee's fight with Barricade), the action starts out in broad daylight and, in an implausibly short time, goes to black night.
When the autobots are in vehicle mode, they are all cleanly polished, shiny and brand-new looking. However when they transform into robot mode, their shells (including identifiable parts from the vehicles) are covered in dents and scratches, even in scenes with no combat. This is most noticeable in the first scene with all five autobots together in the alley. When they return to vehicle mode, they are once again cleanly polished.
When Sam is running from Barricade and hits Mikaela who is riding a moped they fall on the ground and the moped is clearly visible laying next to them on the ground. In the next shot they zoom out and the moped is nowhere to be seen.
When Optimus Prime and Bonecrusher are fighting, they fall from a bridge onto a highway. A car with a mother and child swerves in order to avoid hitting the Transformers, and ends up at an angle, so that in order for the mother and son to see the Transformers they would have to look out of the passenger window. After the cut scene of them swerving to the side, the camera (from inside the vehicle) shows the Transformers fighting right in front of the front windshield.
When Sam leaves his house with the Transformers he is carrying his brown jumper. The scene then changes to him talking with the Transformers and he has his brown jumper on. Then the angle changes, and he has his jumper over his shoulder again.
The amount of donut on Glen's plate while he and Maggie were in the interrogation room keeps changing. After Glen eats the donuts and finishes, only half of a donut remains. But when the FBI agents walk in, it can clearly be seen that there is one and a half donuts on the plate. And when the agent slides the plate to the center of the table, there is only a half donut on the plate again.
Just before Bumblebee spills lubricant all over Simmons, he ejects an object that resembles a car engine oil filter, which strikes Simmons by his right eye. Simmons then reaches up and rubs the back right portion of his head, as if the object struck him there instead.
When we are first introduced to Glen, he is wearing a green shirt and a pair of Washington Redskins-themed pajama pants. Later, when he and Maggie are sitting in the FBI's interrogation room, he's now wearing a Washington Redskins jersey and jeans which he wears for the rest of the film. However there doesn't seem to be any indication that the FBI would have let Glen change his clothes after he was taken into custody.
When Sam and Mikaela are captured by the Sector Seven agents in the causeway, they are pushed face-down onto the pavement and handcuffed behind their backs. As they are dragged away from the scene their hands are clearly free.
During the fight between Bumblebee and Barricade, Sam's pants are removed. Mikaela later picks up her purse and re-enters the car with the pants still clearly in the foreground of the shot. When Bumblebee kicks the two out in the tunnel, Sam inexplicably has his pants back on.
In the initial fight scenes between Bumblebee and Barricade. There will be a time when Barricade is backed up against the camera (facing away from the camera.) Notice the gap of the wheel well. It's huge! There is no rear right wheel. Director's commentary stated they had some problems with the mustangs.
When Bumblebee locks in Sam and Mikaela, the locks are seen to lower so that they are almost flush with the top of the door frame. However, in the next shot of Sam, the door lock is sticking up above the door quite a bit.
At Hoover Dam when Sam is talking to Simmons about how he wants his car, his parents, and Mikaela's record erased, the giant clock behind Simmons skips about 5-7 minutes in a matter of seconds indicating several takes.
When Optimus Prime and Bonecrusher are fighting on the multi-level highway junction, as they fall off the bridge, the corner of the support pillar behind them changes from being in shadow to being in sunlight as the shot changes.
After Megatron and Prime fly through the building and land on the street, Megatron throws Prime down onto the crosswalk, hitting a silver parked car, with 4 other cars on the street. In the following scene from the same view, Prime gets up from much further down the street and has to run up to the crosswalk to fire his gun, and only 1 car (a black parked car across the street) is now on the street.
When Prime gets up to fire his gun at Megatron, there is only one car on the street (a black parked car on the opposite side), but after he fires his gun, the camera pans to reveal a parked cab with 2 people cowering behind it right in front of Megatron, which disappears again after Prime is hit and flies back into the window.
After Sam is clotheslined off his mom's pink bike, he gets up and yells at Barricade, who advances on him several times, pushing him back/away from the fallen pink bike, but when the "eye" comes out of the headlight, the pink bike is right beside Sam and the fender of Barricade, despite driving forward several feet when advancing on Sam.
In the dumpster area scene, Frenzy transforms into Mikaela's cell phone and is on the ground a foot or so away from her purse. When she reaches out of Bumblebee to retrieve her purse and other spilled items laying next to it, she doesn't pick up the cell phone and it is no longer on the ground.
In the first fight between Bumblebee and Barricade when Mikaela runs to the building full of tools and picks up the reciprocating saw, we can clearly see that it has a gray colored, ribbed grip on the front with no buttons. However, after she has sliced up the robot and Sam kicks the head away, she props it on her shoulder and we can clearly see that the handle is now black and smooth with a yellow button on the side.
When "Sector 7" agent Tom Banacheck shows two different ALIEN images to Defense Secretary John Keller he states that one is from the Soccent base attack in Qatar [by Blackout] and the other he explains is an image taken from the Beagle 2 Mars Rover. Both images are shown to have been taken during the day; However, Staff Sergeant Epps (Tyrese) took the thermal image after Blackout had transformed (at night)
When Captain William Lennox is at Sector Seven headquarters at the Hoover Dam, he is seen seen wearing a U.S. Army-issue ACU uniform when he arrives, but later changes to a Future Force Warrior uniform in the Crye MultiCam pattern with no opportunity or reason for him to change clothes.
(17:50 to 18:10) When Sam is getting ready for the party, he says, "Okay Mojo, ready for your pain pills?" in a black t-shirt. The scene changes to him in front of a mirror, and you see him in his party wear (to which he added a short sleeved black striped button-down) and he then goes to his t-shirt again, giving Mojo his medication.
When Maggie goes to Glen's house, she's wearing a short skirt. After she, Glen, Sam and Mikaela are dropped off at Hoover Dam, her skirt is replaced with a pair of calf-length jeans, while the rest of her outfit hasn't changed.
While Sam is looking for the glasses at his house and after the electrical transformer has been destroyed, the electricity to Sam's house is mostly out during interior shots (mostly, because it appears his desk lamp is on with low wattage). When perspective switches to show the exterior of the house, the outdoor lights are on and the interior lights are on which is clearly visible through the windows.
At the beginning of the last fight scene, in the foreground when Capt. Lennox is in the street a woman can clearly be seen on a cellphone. However all communication has been taken out by the Decepticons some considerable time previously, the point made when by the director when Defense Secretary John Keller tried to use his cellphone and couldn't after communication had been "taken out".
In one of the scenes at the Hoover Dam, there is an aerial shot from directly above the dam, looking down. In the shot you can see many cars (tourists driving on the highway that runs on top of the dam) but in the next shot, from ground level, the characters are all walking on the road and there are no cars visible anywhere.
In the alley where Sam, Mikaela and Bumblebee meet the rest of the Autobots, as the camera orbits around the transforming Optimus Prime, Bumblebee can be seen backing up as Ratchet and Jazz pull in to his right and Ironhide to his left. As we pan around Optimus to see them again and the other Autobots are transforming, Ironhide and Bumblebee have switched spots.
At Bobby Bolivia's car yard, when Sam first sits in Bumblebee, there are fingerprints in the dust on the window of the Volkswagen beetle next to them, each time the shot changes, they appear and disappear.
As Sam is in the car when they are fighting the police car, they are seen to have been rolled out of the car. In fact, Mikaela and Sam are just rolling and are not airborne for any amount of time. Also, by this time, Bumblebee was already up against the Police car, just a second after transforming, but the Police car was already up to the house that Bumblebee knocks him into.
When the Sector 7 members show up at Sam's house, Agent Simmons peers through the mail slot and rings the electric doorbell numerous times, despite the fact that only minutes earlier the electricity for the entire street was taken out when Ratchet accidentally walked into a set of power lines.
When you see Archibald Witwicky initially fall through the ice hole, none of the dogs are near him. Immediately next when you see him slide down the hole, he is immediately followed by one of the dogs.
When Sam is at the dealership looking at cars; as the front passenger door is closed there are no visible rust marks. When the door swings open into the beetle next to it, there is a giant rust spot. Then when the door is visible again the rust spot it gone.
In the scene where Megatron and Optimus Prime fall off the building after Optimus saves Sam, they land in front of a car that's just arriving. The car swerves to the left to avoid them. There's a shot from inside the car while it's doing so. During most of this shot, you can see the cameraman in the passenger seat, filming, reflected in the rear-view mirror.
When Bumblebee is speeding along the viaduct, several slivers of yellow light can be seen. As the camera follows Bumblebee, we can see the lighting equipment used to cast the lights in the lower right of the frame and in the background.
Approximately 2 hours into the movie, when Sam falls to the ground and the Xbox and Mountain Dew machines begin coming alive, it pans back to Sam and a camera man is clearly visible just a few feet from Sam on the right side.
When Capt. Lennox and his team keep walking at the middle east of Qatar, they find a metal structure (probably an antenna). Suddenly, the robot which crawls under the sand breaks the base of that structure, causing the structure to fall down. Two soldiers who are in front of that fallen structure wonder what happened, one among them is a guy with spectacles. At this moment the crew and the equipment are visible in the reflection of the soldier's spectacles (when he says "English dude, English".)
Just after Bumblebee has left the car-park after chasing Sam Witwicky, Sam approaches the side of the police vehicle on a bicycle and is knocked down when the car door opens. After a short close-up of Sam on the ground, we see the car-door closing. The driver of the car is clearly visible for about 2 seconds, both reaching for the door, and pulling it closed.
When Bumblebee kicks Sam and Mikaela out in the tunnel (right after she asks Sam why Bumblebee transforms into a "piece of crap Camaro"), a crew member's arm is clearly visible pulling up the manual lock pin; the same arm is seen pulling back (the crew member must be hiding behind the passenger seat) once the door opens.
In the beginning, during the Qatar scenes, you can see mountains in the background. The country of Qatar has no mountains and the highest elevation is 295 feet above sea level. It would also be very unlikely that you would see wooden telephone poles, as we do in the desert scenes ostensibly set in Qatar. Most telephone poles in many middle-eastern countries, more specifically those used away from population centers and in the open desert, would be composed of metal or pre-formed concrete. The main reasons for this being, not only because the extremes of the high heat and low humidity in those climates would dry the wood to the point of breakage very quickly, but also because of the scarcity of logs of the size suitable for that usage.
Maggie Madsen leaves the Pentagon and runs south across the intersection of Wisconsin Ave. and "M" St. NW in Washington DC. The Pentagon however is three miles away via various major highways, too far to travel on foot. Had she come from the Pentagon, she'd have taken a different route that precludes her crossing the intersection in that direction, possibly avoiding it entirely (i.e. by taking K St. NW instead).
The movie referred to "high heat sabot rounds" as being the most effective against the robots. However, sabot rounds work strictly through kinetic energy and the heat produced by them is strictly a by-product. In other words, sabot rounds must travel at extremely high velocity to be effective. However, none of the weapons that supposedly used them in the movie would have been capable of producing the necessary velocity. This could also refer to a High Explosive Anti-Tank (HEAT) round, but that is a large shell with a shaped-charge exploding warhead, unlike the solid projectile of a sabot round.
Glenn Morshower's character is referred to in the closing credits as 'SOCCENT Sergeant'. However, when we actually see him (in the film's opening scenes), he is clearly a Colonel: he wears the rank insignia of a Colonel, and is referred to as Colonel by his subordinates.
The uniforms worn by Captain Lennox's team have patches on their right shoulders from the 82nd Airborne "All Americans" Division, indicating they served with the 82nd in combat. The "Airborne" tab has been incorrectly replaced with a "Ranger" tab. The "Ranger" tab is worn above the "Airborne" tab on the left shoulder when deployed with the unit and it is not used on the right shoulder.
When the gunship rolls in on Scorponok, the special effects show gunfire coming from the forward part of the gunship. The aircraft shown is an AC-130H Pave Spectre, which has not carried armament in the forward compartments for many years now. Further to that the request was for 105mm howitzer shells, the rate of fire from both weapons is more indicative of the 25mm cannon from an AC-130U interlaced with the occasional 40mm Bofors round.
The battle of "Mission City" involved several F-22s firing which appeared to be Aim-120 (Advanced Medium-Ranged Air-to-Air-Missle) AMRAAM medium ranged active radar homing missiles. These missiles were designed to be used for air to air combat as a replacement to the Aim-7 series of medium ranged air to air missiles. No variant of the Aim-120 series can track or attack ground targets because the weapon is employed with an aircraft's air to air radar.
Although the A-10s shown during the battle with Scorponok appear to carry laser guided bombs, they were never used during the battle. Instead, the A-10s engaged Scorponok with a burst from the 30mm cannon and then a pair of air-to-ground missiles, probably AGM-65 Mavericks - neither of which require lasing from a ground team.
During the Sec of Defense briefing, it cuts to a shot of two Blackhawk helicopters flying. Both are clearly marked as MedEVAC by the NATO Red-Cross symbol on the crew doors. In the next shot, a door gunner is shown with what appears to be either a M240B 7.62mm MG, or a M-60 7.62mm MG. This would be incorrect given that it is not allowed by the Hague Convention of 1907 for Medical Assets to have crew served weapons, and still retain their non-combatant status. Nor is this current practice. A more correct formation would be a "standard" Blackhawk flying escort to a MedEVAC aircraft.
Sam Witwicky's eBay user-name is shown on his computer screen as "LadiesMan217" with the L and M capitalized; however, user-names created on eBay can ONLY be displayed as lowercase. The correct visual should be: "ladiesman217"
Throughout the movie the characters talk about using 40mm sabot rounds against the robots. However, there are no sabot rounds for hand fired 40mm weapons. The nearest item would be HEDP (High Explosive Dual Purpose) which uses a shape charge to penetrate limited amounts of armor.
The footage Agent Simmons uses to illustrate the Beagle 2 images is actually from NASA's MER program. Beagle 2 was neither a rover mission, nor did it physically resemble the two Mars rovers (Spirit and Opportunity).
In the scene where Defense Secretary John Keller is giving a public address following the attack on the Qatar Air Base, at one point he says "bases worldwide are at DEFCON delta." DEFCONs levels only go from 5 to 1, 1 representing imminent attack.
While at the Hoover Dam, Captain Lennox is shown wearing the green beret of the U.S. Army's Special Forces. However, the cloth "flash" on the front is the generic light blue flash, which is used on the black berets of regular Army soldiers. His green beret should have a unique flash of his assigned Special Forces Group.
During the scene where they showed the inside of the AWACS aircraft (Airborn Warning and Control System), and you can overhear the communication the controllers in AWACS are using to direct the fighters for ground support, they gave the coordinates of 'Eighty-Eighty Alpha Sierra.' These types of coordinates are CGRS (Common Grid Reference System) In the movie, they were directing aircraft to a location somewhere in Egypt. the coordinates 'Eighty-Eight Alpha Sierra' (Written as 88AS) are in the very center of IRAQ, not Egypt. The communication they used were obviously taken from recordings from the CRC (Control and Reporting Center) named 'Kingpin' in Iraq.
Sam's dog, Mojo, has a cast on his broken leg made of plaster, which hasn't been in widespread use in the medical or veterinarian communities for more than a decade. According to the movie, this also must be a recent injury because Mojo is still requiring pain medication. Unfortunately, the portrayal of the injury is not entirely accurate as we see no "Elizabethan" collar on Mojo. Animals recently injured which require splints, casts, surgery or stitches would be discharged with a proportionally large plastic collar around their necks. This, of course, prevents the animal from biting, licking, tearing out the stitches or just exacerbating the injury. At this point, Mojo should still be required to wear such a collar.
An F-22 pilot mentions his ETA as being time on target. "Time on target" has a specific meaning in military parlance; to fire an offensive volley so as to have all artillery hit the target at the same time, not as an actual measure or estimate of time.
When Agent Simmons places the detector near Sam, he reports that he's seeing 14 Rad. Presumably, Sam has become contaminated by proximity to Bumblebee and the other auto-bots. If Sam is emanating 14 Rads, being in close proximity to him would be fatal in about 24 hours. Sam would certainly be dead himself by this point. Later, in the SUV, the detector starts to click again as the Autobots approach to rescue Sam and Mikaela. The switch is in the first position above off, which is the battery test position. It would not respond to changes in radiation in this mode.
When Mikala looks under Bumblebee's hood she mentions that the distributor cap is loose. The engine shown is a Chevrolet V8, either an LS7, or a supercharged 6.2L LS3 , neither of which has a distributor. Both engines use individual coils for ignition in each cylinder. And even if the engine shown were custom modified, there is nowhere to install a distributor.
The Airforce One displayed in the film is a 707/VC-137, from the markings most likely VC-137C SAM 26000. Considering the time setting the 747/VC-25 based version would be a better match. Also the marking do not match a real Airforce One version precisely.
During the Autobot introduction, Sam's pheromones are mentioned. Humans do not produce pheromones; we react to chemicals released by bacteria living in sweat and other body fluids, and the odors those bacteria produce are not affected by human sexual arousal or thoughts.
Ironhide complains about his foot rusting after Mojo "leaked lubricants" on him. Yet he crash landed in a pool when coming to earth and said nothing of rust. However, urine is essentially a diluted acid with salts in it, which would be more corrosive to ferrous metals than chlorinated pool water, so it could be that Ironhide's metal skin is rust-resistant but not rust-proof. More likely, however, is that he was grousing and exaggerating in the process, much like real people do; or just that he didn't complain at the time of landing in the swimming pool as there was nobody to complain to.
When the Cube is revealed a the secret base, we're told carbon dating has determined it to be on Earth since 10,000 BCE. Carbon dating is in fact accurate to within about 9 half lives of the carbon 14. 9 half lives of carbon 14 ( at 5280 years per half-life) gives an accuracy limit of about 50,000 years. 10,000 years BCE is well within the time frame able to be determined by radiometric dating using carbon ratios, and would in fact be the most accurate dating method for something in this time frame.
When the F-22 intercepts the helicopter 4500X the audio pronounces the tail number as "forty five hundred x-ray." Aviation standards require most numbers be pronounced individually and should have been pronounced "four five zero zero x-ray." However, most controllers are more compulsive than pilots about this and pilots would commonly abbreviate this to either "fourty five hundred" or "four five hundred".
The relationship between Captain Archibald Witwicky and Sam Witwicky keeps on changing throughout the film. At different points during the movie, Archibald is said to be Sam's great great grandfather, great grandfather, and grandfather. However, he could have just gotten tired of saying "my great-great grandfather, Archibald Witwicky..." He seldom said "great-great" other than in his report.
When Sam is in his class giving his presentation, he mentions that the sale price of his Great-Great-Grandfather's swag was to be put toward his "car fund", yet he clearly indicates to the teacher at the end of the class that he already has the $2000 he needs. However, it is very possible that Sam was planning on investing in his car or hoping to be able to buy a better car with more money.
When Mikaela leaves Sam after looking at his engine, the passenger door is open. When Sam starts the car, and closes the hood, the passenger door is closed. However, Bumblebee has shown himself able and willing to open and close his doors whenever he wants.
The movie states that the robots are radioactive (they even use a "Geiger-Müller tube" to detect their presence). Given that Geiger-Müller tubes can detect even a single particle of ionizing radiation (even in the presence of no radioactive material they will still quietly click away due to normal background radiation), it's quite feasible that the radiation levels of the transformers is not sufficient to noticeably harm any of the humans they come into contact with, given their relatively brief exposure and the human body's ability to repair moderate amounts of radiation damage.
The yellow "1971" Volkswagen Beetle briefly shown in the scene where Sam is picking his first car at the dealership is actually a 1973-1977 model (and in fact a Super Beetle, a different model than the common Beetle). This may be a gag about the proverbial dishonesty of car dealerships.
After all landlines and cell phones are to be shutdown, people in the background of the fight scene in the city are seen using their cellphones. Although, it doesn't necessarily mean that they were talking. A possible explanation for this is that they were trying to phone their family/friends, and failing.
During the Freeway chase, Decepticons: Bonecrusher and Barricade together are in pursuit of the Autobots. Bonecrusher pulls ahead to battle Prime, tearing up the roadway by dispatching hapless motorists. Barricade, however, disappears and does not reappear nor is he mentioned again for the rest of the film.
Upon arriving at the Hoover dam Starscream destroys a power substation. Reacting to this the engineer informs Banacheck that the MBE hangar has lost power. Logically, however the power system would be contained within the dam's structure preventing an attack like that from happening. The substation would service nearby communities not the dam.
In the highway scene, right up until the shot when Bonecrusher tackles Optimus Prime, the road they are on is clearly ground level. In the shot immediately after, they are seen tumbling off an elevated highway road, falling onto a lower elevated road. Then they fell off again and finally reached ground level where they continued fighting.
In the city fight scene, a large piece of a building falls onto the left side of the street, yet when a citizen passes by (and probably accidentally kicks it) the piece appears to move as if it weighed nothing.
When the vehicle with the S7 officers holding Sam and Mikeala is attacked by the Autobots, it is clearly shown more than once that the SUV's gear stalk is in the "park" position. It is most visible when the vehicle's roof is torn off and the SUV lands on the ground.
When the Predator flies over the desert to the fight with Scorponok, there is no shadow of it on the sand, a result of the Predator being CGI. A similar issue occurs when Ironhide comes out of the pool and walks directly over the girl with the tooth, meaning the girl should be wet from the pool water dripping over her off of Ironhide. But she isn't, due to the fact Ironhide is CGI as well.
At the Hoover Dam the water intake tower clock has the 'Arizona' wording digitally removed from the clock image when shown close up. However in a following shot the full 'Arizona Time' wording is visible (although out of focus).
Several bits of footage are reused in the movie. When the Decepticons mobilize, the footage of Blackout is the same footage from his approach and landing (notably the pilot in the cockpit at night, which switches to the chopper banking before the F-22 fly by over the desert during the day) in Qatar, and Barricade driving down the street in the city, passing up the same black Cadillac as he did before he confronts Sam the first time.
Right before the debriefing of the analysts the movie shows a helicopter flying towards the Pentagon. Right before this the Washington Monument is shown. The top third of the monument is crooked, indicating a clear glitch in the software.
When the Decepticon tank Devastator / Brawl is running over a BMW during the Mission City sequence, it is obvious that the prop is not even close the the weight of a real tank; it barely crushes the vehicle at all, riding right up onto the chassis. As it does so, it is also visible that it has rubber band tracks rather than the Diehl 570P tank treads of a real Leopard II or Abrams; this is because the running gear is from a piece of construction equipment, not a tank.
in the scene when Barricade (The Police Car Decepticon) is attacking Sam, when he throws Sam into the windshield of a parked car, you can clearly see that this is not their first take, you can tell that by where he gets thrown, the impression is already on the windshield.
After the Autobots have left Hoover Dam and are being pursued by Barricade, Bonecrusher, and Brawl (Devastator), the Transformers and extra cars are all driving on the wrong side of the road. Highway signs directing the flow of traffic are visible while the chase scene takes place in the opposite direction stated by the signs. (at around 1h 50 mins)
When Mikaela is walking away from Bumblebee after looking under the hood, and Sam is trying to get the engine started, the passenger door is open. As the engine roars to life, and he gets out to close the hood, the passenger door has closed with no indication of someone closing it.
When the surviving base attack U.S soldiers call for air support, its information is relayed to the M.A.G.I.C air watch dog airplane. The screens on board are blank. Technically they are plotting positions for the air support which they can't because the screens are black.
The goof items below may give away important plot points.
After the soldiers are fired on by Starscream in Mission City, Epps tells Lennox that it had to be an Alien attacking them because friendly aircraft would never fly below buildings. Yet, when the friendly F22s attack Megatron, that's exactly what they do.
When Bumblebee takes the car over, after Sam picks up Mikaela and parks, she opens the door to go look under the hood. You can clearly see in the foreground of the shot that there's a black mark on the passenger side door/fender. It disappears in the next shot and is never seen again.
As Mikaela runs towards Sam before he begins running with the cube she passes Bumblebee on the tow truck. But as she faces Sam you can see the tow truck behind her and Bumblebee is nowhere to be seen. Yet as she runs back to the tow truck Bumblebee reappears.
In the fight between Megatron and Optimus Prime, there is a yellow Pontiac GTO shown for a second before it is torn in half. Before its destruction, the GTO's rocker panel is clearly already in two pieces which are not properly attached to the vehicle.
