During the shootout on the freeway, Mike shoots and kills the same Haitian twice.
In the Macarthur Causeway chase sequence, the characters drive over the same bridge repeatedly. As a result, you can see them passing the Miami Herald building at least four times.
During the Yellow Hummer chase scene, the driver side mirror is knocked off and reappears several times.
When Marcus and Mike are the exterminators, Mike leaves his tool belt on the floor. But when he leaves the house he is wearing it.
When the yellow Hummer leaves the mansion it has a sun roof but later in the chase scene it does not have a sun roof but has an overhead consul.
When they arrive at the base at Guantanamo, Tapia tells the cops that the Americans can't help them because they are still on Cuban soil. The Marine tells them that they are standing in a minefield. At Guantanamo, the minefields are INSIDE the fence, on the American side - not on the Cuban side. Furthermore, there is no hard wall surrounding the U.S. Naval base at Guantanamo - it is all chain-link fence.
When Marcus comes out of the shower after accidentally ingesting two ecstasy pills, he tells Mike and Captain Howard that he has an erection. Ecstasy, like all amphetamines, makes it harder to get and maintain an erection, so despite the drugs 'loved up' effects a spontaneous erection would simply not happen.
Rats don't mate facing each other.
It is not possible to shoot through a thick steel chain with a handgun.
Even though many movies depict it this way, you cannot release cars from a carrier by releasing a handle or breaking a chain. Each car is individually secured to the carrier rack by chains and straps.
During the car chase scene, when Mike and Marcus do a 360 in their car, you can clearly see it is a Caucasian stunt driver with dark sunglasses doing the actual 360 spin. Once that is done and the car is accelerating forward, it is Mike back in the driver's seat.
The money in the coffin in the funeral home is marked "For Motion Picture Use Only" (This was digitally corrected for the DVD/VHS).
When Marcus is swept into the ocean after the pool breaking, you can clearly see that the water continues to flow though the pool is almost completely empty.
Cables visible on stunt players during the explosion during the gunfight with the KKK.
During the initial shoot out at the mansion in Cuba, black squibs can be seen floating in the swimming pool just before they go off.
In the very start of the shootout at the Haitian hideout, when Marcus says "You got to call yourself the devil in his house?!", but his lips say, "You got to call Mike the devil in his house?!"
A lot of the scenes that involve the Ferrari 575M/550 Maranello do not portray its engine sound correctly - the sound is that of a raspy Ferrari flat-crank V8 engine, not the 575M/550's quieter, more refined V12.
When a police cruiser overturns at the end of the causeway chase sequence, a camera can be seen flying out of the driver's side window.
When the police car flips over, you can see the compressed air gadget on the underside of the car.
When the Haitian gets into the semi's cab before the causeway scene, director Michael Bay is seen operating a camera for a handheld shot in the background. Behind him is much of the crew.
When Mike is driving towards the Haitians whose cars are piled up, he brakes and the car turns. As the car turns and Mike pulls out his gun, a stunt driver is briefly seen in between shots and it then cuts to Mike's face immediately after.
After the freeway chase, when Marcus opens the passenger door of the Maranello 550 under the overpass, as the door swings open you can see a bunch of onlookers in the mirror.
One of the early scenes is supposed to show "Amsterdam Harbor", despite a number of revealing inconsistencies: Firstly, there are palm trees visible in the background, which do not grow in Holland; secondly, the vehicles shown at the harbor are so-called "conventional cab" semi-trucks with a protruding front, rather than the cuboid "cab-over trucks" you would observe in continental Europe; and the actual port of Amsterdam is much smaller and cannot handle the large cargo vessels featured in the scene.
The size of the harbor shown is more reminiscent of Rotterdam Harbor, the biggest in both the Netherlands and the whole of Europe; perhaps the naming was artistic license because American audiences would be more familiar with the name of Amsterdam.

In the harbor, someone is making a phone call from a "public" phone. The phone is clearly visible, but it isn't a phone that's used in the Netherlands. There are green public phones, but the design and logo are different. Also, there is a label on the phone booth which reads "Dutch Telecom". This company does not exist at all. The correct text would be "KPN Telecom".
[2:12:56]During the car chase scene in Cuba after leaving Johnny Tapia's home,on a building marked "Alcaldia", there is a flag which is not the Cuban flag.
It is pointless to smuggle synthetic drugs like ecstasy. One of their major benefits is that you can synthesize them anywhere from more or less legit precursor substances and thus avoid crossing heavily controlled national borders.
By entering Johnny Tapia's house illegally, all the evidence Mike and Marcus collected are useless in a court of law.
No reason to go without judge and warrant on that wire tap since they have plenty of evidence for probable cause.
When Syd shows up to clean the money for the Russians they go into a room where a woman is placing ecstasy tablets into little bags. The woman is not wearing gloves and would eventually overdose from absorption of the drug through her skin.
Mike orders the speedboat driver to shut the engine down. His Spanish words are "Cierre el barco," which would never be used in any context. They mean something like "close the boat's doors." Proper orders would be: Stop (deténgase), stop the boat (detenga el barco), or shut the engine down (apague el motor). A police officer in Miami would be aware of these forms, given the large Latino population.
At the beginning of the movie, when the girl is messing around with Tapia's handgun, the gun supposedly goes off accidentally, yet the actress clearly closed her eyes just before the gun discharged, in anticipation, just before pulling the trigger.
In the beginning of the movie when the helicopter takes off from the Coast Guard Cutter, the helicopter pilot can be heard calling the cutter with a callsign of 6003. The helicopter is clearly an HH-65 Dolphin and would have a callsign of 6503.
A police lab analyst identifies Kuninsevich to Mike and Marcus as "a lieutenant in the Russian mob". No Russian organized crime syndicate uses "lieutenant" as a designation.
