Megatron says "No more hiding" referring to the Decepticons no longer camouflaging themselves or imitating other objects, but some Decepticons still imitated Earth vehicles and aircraft, such as the Devastator bots, which were even motionless when they were being stood next to and in hearing distance of humans babbling loudly. One of the Decepticon jets was also shown with a pilot inside, which seems to go against the "No more pretending" line.
During the scene in which Leo, Sam, Mikaela, and Simmons are going through the Egyptian check point (run by Deep Roy's character), Leo states to Simmons, "I can handle it. These are my people. I'm 1/36th Arab." It is almost mathematically impossible for someone to have a hereditary factor of 1/36th. They probably meant for Leo to say, "I'm 1/32nd Arab." This would have been very easy to do, as a great-great-great grandparent would be 5 generations back, speaking in genetic terms. And 2 to the 5th power is 32.
When Agent Simmons asks Wheelie where to find the older Transformers, Wheelie shows them by pointing lasers at a map of the United States. Simmons says "The closest one is in Washington," and they go to the Smithsonian Air and Space Museum in Washington, D.C. However, none of the lasers actually pointed at Washington, D.C.; the closest one pointed to eastern New Jersey.
When Sam's parents take him to college for the first time, you can see his mom clearly high off of marijuana brownies. Marijuana, when consumed in a food, takes about an hour before the effects are felt.
Over the course of the movie, characters take props out of nowhere. At the beginning Sam takes out pincers and a special receptacle to put the shard in it; and when Bumblebee blows up a hole through the tomb of the Primes, Sam and Simmons point lanterns inside the hole.
In the scene where Bumblebee and the other two Chevy hatchback Autobots are driving through the desert and come under Decepticon attack before the big battle at the pyramids, the same shot of Decepticon-fired shells hitting the sand around the vehicles and the vehicles swerving to avoid these strikes is used twice.
During the Shanghai Chase Scene, Sideways runs through a building and transforms on the other side. If you look closely, you can see the wall he approached in the former shot, and the wall he is leaving behind are the same wall on the same street. He didn't go through the building, he made a huge explosive U-turn.
When we see Mikaela for the first time (on the motorcycle, painting a devil on the side), she is lying forward on the bike, leaning over the right side. When the shot changes, she is leaning over the left side of the bike.
When Sam is kissing Alice on the bed there's a fan in the window, but when Mikaela comes back into the room and throws the box with Wheelie in it at Alice the window is closed and the fan is leaning against the wall.
Sam, Mikaela, Leo, Bumblebee, and 2 other Autobots hide out in the old brick building. As the humans are run out to leave, Bumblebee drives around the building with them already in the car. In the next scene they run out of the building, jump into Bumblebee, and drive off.
(at around 40 mins) When Sam is talking on cell phone outside on campus, going down stone steps, a girl in flowery shirt and cut-off jean skirt passes him as he's picking up papers. He continually talks as the camera changes angles, and the same girl is yet again walking by him, even though she was 8 feet past him 1/5th of a second before.
When Sam is showing Wheelie pictures of Project Black Knife, the pictures he is holding of the buggy and plane change hands several times, and the plane changes from being on the ground to being in the air.
When the Autobots are in the hangar, and Optimus Prime is doing his report to the general, director Galloway interrupts them and talks about their weaponry. The scene repeats at the end, when he asks if the Autobots would leave the planet peacefully.
When Sam is about to leave home for college his father is packing the car, he carries a set of golf clubs over his shoulder, in the next shot they are not there, then they reappear on his shoulder again later.
When they arrive at the quarry in Bumblebee, Simmons stabs Leo in the neck with a stun gun, which knocks him unconscious yet in the next frame you see all four characters getting out of the car including the now conscious Leo.
During the forest battle, when Starscream accidentally shoots Grindor with a missile, Grindor is damaged and loses a big part of his right shoulder. But a few seconds later, Grindor is seen to be undamaged.
When Sam visits Simmons, his blue jacket is unzipped. Then in the Air and Space Museum, his jacket is zipped up and then unzipped again when Jetfire breaks out into the plane boneyard. In three consecutive scenes, his jacket goes from unzipped, to zipped, then back to unzipped.
During the aerial scene showing Bumblebee, Mudflap, and Skids driving down the road headed to Jordan, the sand is a reddish brown and there are large rock formations. When the camera pans down to show the front of Bumblebee's Camero alt. form, the sand is now white, rocks have disappeared, and there is a wire fence with wood posts visible on the right side of the screen.
As Jetfire smashes his way out of the Kennedy Space Center he turns to speak to Sam in the airfield. As he does so he knocks one of the wings off the tail of one of the aircraft accidentally with his staff. A few moments later the same shot is used and the same tail section is completely intact.
In a single shot, when Devastator starts to form the whirlpool, the camera pans and a man screams "Ayuda!" (for 'help' in Spanish), the pan continues past a truck to reveal Leo and Simmons. Then Devastator's whirlpool sucks the truck and the man who screamed is not seen.
(0:50:05) When Leo and Alice find Sam writing Cybertronian symbols on the walls, on small bits throughout the scene you can see that Sam's got Cybertronian marks in his arms (the ones he shows to the twins later in the film); yet he doesn't get them until some 6 or 7 minutes after, when Megatron holds his arms with his claws.
As Sam and Mikaela make the final run to Lennox and Epps, it is apparent that the continuous scene was filmed at different times of the day. Shadows change as well as lighting; darker evening coloration with Lennox and Epps, and brighter midday lighting with Sam and Mikaela.
During the scene in which Leo, Sam, Mikaela, and Simmons are going through the Egyptian check point, Wheelie pops up between Sam and Simmons, but Wheelie is never seen again in the movie. When everyone gets out of Bumblebee so he could create a diversion, Wheelie should of stepped out too, but he did not.
When the Decepticons travel on a ship to revive Megatron, one of them is disguised as a wheel loader. When Ravage impacts just seconds later, the wheel loader is gone and replaced by a bagger. During the same cut, the cement mixer obviously moved back (where there wouldn't be any room according to the first shot) to make room for Ravage, who's lurking around the bagger tracks in the next scene.
When Sam, Mikaela, Leo, Skids, Mudflap, and Bumblebee decide to continue instead of going to the authorities, Bumblebee transforms into the Camaro and nudges Sam by rolling forward a short distance, then reversing. As Bumblebee backs up, a driver wearing a balaclava is visible.
When Jetfire is reactivated at the Steven F. Udvar-Hazy Center in Virginia, he blasts open a hangar door and steps outside. The exterior shot shows him and the other protagonists in the "bone yard" at Davis-Monthan Air Force Base in Arizona.
In a few scenes in the movie, the USAF characters are at a military base in New Jersey, with a desert-like environment and mountains in the distance. New Jersey does not have a desert or big mountains.
The scene involving Egypt, Jordan, and the Bay of Aqaba is a geographic mess. Petra is almost 1,000 km. from the pyramids, which are just outside Cairo, which is hundreds of kilometers inland from the Mediterranean.
When the characters go to The National Air and Space Museum in Washington, D.C. to locate the SR-71 Transformer, the SR-71 breaks out of the hanger to go outside. They are now clearly not in D.C., but are at the "Aircraft Boneyard" located in Tucson, AZ.
In Transformers Megatron was dropped into the Laurentian Abyss in the Atlantic Ocean. In both movies this is erroneously portrayed as being deeper than it is in reality. "9,000 fathoms" is given in Transformers: Revenge of the Fallen. In fact, the deepest point in the ocean is the Mariana Trench in the Pacific Ocean, which is almost 6,000 fathoms deep.
When the medical helicopter flies in during the end battle, you can see "White Sands Missile Range" written on the side of the door. The battle is supposed to be in Egypt; a WSMR helicopter would not be there. The aircraft was painted red, white, and Blue. The medic was wearing US Army ACU body armor, implying that he was on a "tactical" aircraft, so the plane should have been olive green. it also should have been a BlackHawk, not the Huey depicted.
When they leave America, it is the middle of the day. They arrive in Egypt at the same time as they left, yet it is the middle of the day there too. Egypt is 8 hours ahead of New York, so it should be evening when they arrive.
When the film begins, at 10:14 pm in Shanghai, it is still slightly light outside, especially at the horizon. At that hour in the summertime, the sun have gone down. There might be some light in the sky, especially if there was a full moon. (Shanghai is 8 or 9 hours ahead of Zulu Time (GMT), meaning the events of the movie would be after dawn and occur in broad daylight, which is obviously not the case.)
When in Egypt, the sand changes from red to white. The scenery also dramatically changes during the final Pyramid fight, as there is red sand and large rock formations in the pit with Leo and Simmons; and there is white sand and rolling dunes where the Autobots and Sam are. The two protagonist groups are not that far away from each other, making the dramatic changes physically impossible.
When the USS Topeka (SSN-754) is operating on the surface, the footage shown is an early flight I Los Angeles Class submarine. The Topeka is a 688I class; its diving planes should be on its bow, not its sail.
When Lennox is giving Galloway a parachute in the plane he asks him if he is familiar with the MC-4 parachute. However, when Galloway pulls the cord and gets pulled out of the plane, his parachute is round. The MC-4 is actually a ram air parachute that is rectangular in shape.
The handheld GPS unit Agent Simmons uses in Egypt (Garmin GPSMAP 60CSx) is shown being viewed sideways while in reality maps are only shown on it in a vertical format. Additionally, the graphics shown on it in the movie are much more detailed than the real unit is capable of producing.
In the opening sequence (dated 17,000 BC) what appear to be African tribesmen are show hunting a tiger. Tigers have never been indigenous to Africa. In fact the last common ancestor of tigers and other big cats probably left Africa 2 million years ago. Modern humans first left Africa 70,000 years ago and began to diverge so humans hunting tigers in Asia 19,000 years ago would not have appeared African.
While the cargo planes are marked AETC on the tail. AETC is "Air Education Training Command", which is only used for training pilots. Once a pilot is trained on a cargo plane, they would fly for AMC, "Air Mobility Command". However, since NEST doesn't officially exist, flying under the AETC could be part of their cover so not to expose the existence of the Autobots.
According to the creators of the film, the Constructicons are a legion of robots with one of seven body types. This is why Long Haul (Green Dump Truck), Rampage (Bulldozer), Scrapper (Yellow Scoop Loader) and Mixmaster (Cement Mixer) can fight Bumblebee's group, while also seemingly being part of Devastator at the same time.
When the Transformers are in robot form, their paint jobs are chipped, scratched and weathered. When they are vehicles, the same paint is super-glossy and waxed with no blemishes. However, it could be possible that they use the same hologram system that they use to create fake drivers.
When Skids and Mudflap enter the military hangar to upgrade from the ice cream truck, they get to choose between becoming a Chevy Beat and a Chevy Trax. Skids chooses the Chevy Beat, which already has his name on the license plate. However, given the lower intelligence of these two robots the military may have already had their names on the plates in order to avoid the fight that happened anyway (the fight of who was going to be what car).
During the F-16 air strike, several of the F-16's are Thunderbirds, painted red, white, and blue. Although these are used for air shows, they are maintained in a fully combat-ready state (except for the paint scheme and the addition of a smoke generator) and could readily be pressed into service in a time of emergency.
While flying over the desert, you can see a pilot inside Starscream. In previous shots (the 3 riders on the motorcycles) and in Transformers, Transformers often use "digital pilots" to enhance their disguise. Although the digital pilot would not really work since Starscream has a bunch of tattoos, it could just be a "default" setting to display the pilot when in jet mode.
According to the Secretary of Defense in Transformers there were no survivors from the base attack in Qatar. In this movie Glenn Morshower (SOCCENT Colonel Sharp) returns and is now General Morshower. As indicated by the different name, this is an entirely different character from the one who died in Qatar.
NEST is actually part of the US Department of Energy rather than Defense, as the acronym stands for "Nuclear Emergency Support Team." However it's entirely possible for two groups in two different agencies to share an acronym, especially if one of them is secret. Given that the Transformers are radioactive, making the public confuse their unit with the Nuclear Emergency Support Team would work to their advantage in keeping them secret.
At the end of Transformers, Frenzy is killed by his own weapon, cutting his head in half. In this film, the head is in Simmons' secret room, in a glass case, fully intact. Simmons likely repaired the head as a trophy.
None of the Transformers transform in the same manner twice, or transform in the same manner as they did in Transformers. ILM deliberately animated the transformations uniquely so that the movements could follow smoothly from the character's actions, such as Bumblebee emerging from the garage at the start. It can be taken for granted that these Transformers, unlike those in the cartoon, can vary their transformation.
When Soundwave orders the Decepticons to mobilize, a shot of 4 robots flying to earth is the exact same shot of the Autobots coming to earth from Transformers. Although it is the same shot, more falling protoforms have been added in the background to give the impression of mass invasion.
When they go to meet Agent Simmons in New York City, there is a shot of the Brooklyn Bridge with the American flag on the eastern tower of the bridge. Although, earlier in the film, the Constructicon Mixmaster knocked the flag off the tower who is to say that the flag had not been replaced. As patriotic as Americans are they may have had it quickly replaced as a sign of strength.
The Air Force character Epps was a Technical Sergeant in Transformers and is a Chief Master Sergeant in Transformers: Revenge of the Fallen which takes place two years later. It is plausible that he was able to make rank that quickly as he did help to save the world from the invading Decepticons in the first movie.
When Sam's mom eats the cannabis brownie she gets high in what seems like 5 or 10 minutes. The director's commentary and deleted scenes reveal that more time has elapsed than that but is not shown on screen in order to move the story forward.
When Sam and Mikaela are driving away from the college with Alice on the hood, Mikaela slams the car into a pole and drives away. The airbags do not deploy. Air bags do not deploy 100% of the time. Moments later, Megatron drops the car into a warehouse. The airbags deploy because the impact was much greater.
An overhead scene of the Pentagon identifies it as "The Pentagon - Washington D.C." The Pentagon is in Arlington, Virginia, but Arlington's politics and economy are heavily dependent on Washington, so many Arlingtonians refer to as themselves as living in Washington.
Megatron tells Starscream that it is time for the Decepticons to let the world know of their presence. To that point, Transformers have destroyed a gigantic chunk of a major metropolitan city in America, a large chunk of Shanghai, have had battles in four other continents, rampaged across a major college campus, destroyed a forest, and stomped around the Witwickys' backyard multiple times. There is no conceivable way that the human race does not know of the existence of the Transformers at this point.
A group of F-16 fighters flying in formation bank off to engage the Decepticons. Inexplicably, they each launch flares, a decoy for heat-seeking missiles, as they break formation. (This is likely because it's stock footage of F-16s on maneuvers.)
When The Fallen takes over the TVs and demands "this boy", a Social Security card is shown bearing the number B216-31-1892, and the name "Samuel James Witwicky". Several frames later, a totally different Social Security card is shown bearing the number B5420-29-8261 and the name "Sam Witwicky". Obviously the numbers are intentionally fictional, but they should not differ.
When the NEST team is in the cargo plane over Egypt, the pilots announce that they are having a problem with the plane. The plane Major Lennox is in rolls over to an almost 90 degree angle before straightening up. In the cargo hold the soldiers are only slightly jostled. But all of the soldiers should have been slammed into the port side wall by gravity during this maneuver.
The goof items below may give away important plot points.
In the areal shot of the USS Theodore Roosevelt, a number of F-14D Tomcats are on deck. The United States Navy retired its last Tomcats on Sept 22, 2006. When the carrier is sinking, no Tomcats appear. This is likely due to old file footage being used for the initial shot, and CGI for the sinking.
In the climactic battle in the desert, Sam, Mikkeala, Lennox, and Epps run from the building as the bombs are explode. As Ironhide emerges from the smoke, his left arm cannon clearly falls off as he runs. When the Fallen arrives and knocks all the Autobots over taking the Matrix of leadership off Optimus Prime, Ironhide has both arm cannons intact.
After Devastator has ripped off the top of the pyramid, Agent Simmons gives coordinates to a US Navy aircraft carrier. Simmons is supposed to be on the same pyramid, but you can clearly see the same pyramid in the background without any damage.
When Sam runs into the car to escape Alice, she sticks her 'metal tongue' through the windshield, smashing the window on Sam's side and leaving a jagged edge. In the next shot, the window is fixed (a new whole window). As they drive away, the window has been cut away cleanly, with no jagged edges.
When the Decepticons destroy the USS Theodore Roosevelt, EA-6B Prowlers (they look like an A-6 with a "football" on the tail) can clearly be seen forward of the bridge, their traditional parking place on the flight deck. When the ship sinks, the Prowlers have been replaced by SH-60s, which are sliding down the flight deck.
Only one Pyramid in Giza, the Pyramid of Khafre, has a smooth top. The machine to harvest Energon is hidden in that pyramid, and the whole fight takes place there. You can see the smooth top when Devastator is climbing the Pyramid. However, every shot is taken on the Pyramid of Khufu. For example, when agent Simmons is climbing the Khufu Pyramid, Khafre, which he should be climbing, is visible in the back.
When the Decepticons sink the carrier, the hull number changes from changes from 74 (the USS John C. Stennis, the ship Simmons radios for the rail gun fire mission) to 72 (the USS Abraham Lincoln) and then back to 74. News reporters later identify it as the USS Theodore Roosevelt, whose hull number is 71.
One of the reasons for sending Megatron down into the deep ocean was that it was cold to keep him frozen. According to the Prequel Comic, Megatron was frozen on Earth due to a lack of Energon. Whereas, the drop team that revives him was more than likely fully-energized and capable of resisting the cold and depth of the ocean.
Soundwave announces that Optimus Prime is dead before he actually dies. This is because he's in contact with Megatron and Megatron has stopped his attack, something he'd only do after knowing Prime was going to die. Thus although Prime wasn't physically dead, there was no doubt he was finished.
Near the end when Sam and Mikaela are running towards Prime, on the last Airstrike, when they drop the large bomb, at least one viewer thinks an explosion/reflection can be seen over Mikaela but not Sam, a compositing error. This is not possible - this shot was a "practical effect" in which the explosion was actually set off behind the actors, and according to the cast it set the world record for the largest special effects explosion performed with actors on set.
Only a prime can kill a prime, thus Optimus must be revived to kill the Fallen. Megatron easily killed Optimus,Optimus Prime is not an original Prime he is only a Prime by being the next leader of the Autobots and by having the Matrix of Leadersip thus having Megatron kill Optimus is a possibility.
Sam was lying on ground after explosion and has swollen jaw and burn on left cheek. When he stands up to hug Mikaela he has no burns on cheek and his jaw is no longer swollen. This is no doubt caused by the power of the Matrix of Leadership bringing him back to life.
During the scenes in the desert, some have claimed that Mikaela's white jeans stay perfectly white. However, it is obvious that they become dirty as the battle progresses though maybe not as fast as some may think they should. This is obvious in the seen when Sam is injured - her jeans are dirty. It also should be noted that the sand is white too.
When the pyramid eating robot is throwing rubble on the Sphinx, in the foreground, there are pigeons on the nose of the sphinx. This is not a mistake as that is actual footage of the sphinx as noted in the director's commentary.
The "three kings" stars of Orion's belt were supposed to mark the location of the hidden tomb of the Primes, as seen at sunrise from the Dagger's Tip. But stars are at a slightly different point in the sky at sunrise each day, so they could not accurately point the way to the tomb at sunrise except on one day each year. No date was specified in the clue.
When the Decepticons go under water to revive Megatron, the Navy states that 5 "objects" went under water. If one of the Decepticons was killed to bring Megatron back to life, 6 "objects" could not have come out of the water: Ravage spits out the Doctor Robot (5+1=6), one gets stripped into parts (6-1=5), Megatron gets reactivated (5+1=6), and Ravage swallows the Doctor to head back to the surface (6-1=5).
Mikaela and Sam are running through the desert. They are being shot at; explosions going off around them; they jump and fall off buildings that explodes and collapses around them and when everything is over, Sam's clothes are in rags and pieces and he is burned, scarred and bloody. Meanwhile Mikaela, who has gone through the same ordeal as Sam, looks like she's just left the make-up chair.
