When Isabella and Jesus discuss what to do with Crockett and Tubbs, they speak in English. Yet, both Spanish speakers, it is unclear why they do not converse in their common native tongue. (However, it is possible they filmed it in English to make it easier on the audience instead of having to read subtitles.)
In the final shootout, Gina gives Zito the green light to move to take cover behind some large wheels. But he walks to safety passing the front of the car where the firepower is, instead of round the back.
When the Aryan boss calls to change the final meet location to the shipyard, its still dark out. But when Tubbs and Crockett drive off to the to the meet the sky is much lighter. When they arrive at the shipyard it is again pre-dawn darkness.
When Crockett and Tubbs are cleaning guns at the aircraft hangar a helicopter is visible behind them. After the camera angle changes and returns, a white airplane is now behind them in front of the helicopter.
In the opening nightclub scene, the first shot of Crockett (over his shoulder) reveals him to be clearly wearing a white shirt under his suit- the collar is plainly visible. Cut to the next shot, from the front, and he is wearing a black t shirt instead.
When Sonny and Ricardo is walking on the streets in Haiti on the way to meet Yero in the restaurant. Sonny has no hair gel on. But when he walks in the restaurant. He has hair gel on and his hair is all combed back.
When Sonny and Isabella drive off from the shooting at the end of the movie, Isabella attacks him in the car. As the car turns around, the gear shift is in drive, when Sonny constrains Isabella it is in park, and when he drives on it is in drive again. Sonny does not touch the gear shift in between.
Crocket wrestles a guy to the ground right before they storm the trailer and his body armor goes from having the shoulder straps ripped off when he stands up, to being fully fastened as soon as the camera changes to him peering around the tree (next camera angle).
When Sonny tells Isabella to put some money aside and drop out of the business before she gets hurt, Isabella's earrings are swaying quite a bit when the camera is facing her, and they are still when the camera is behind her.
When Crockett and Tubbs are driving to meet the chief after their confidential informant jumps in front of the truck, you can see the lights in the bottom of the Ferrari's visor used to light their faces in the car for the camera.
In the scene outside the hospital when Crockett is loading his guns into the trunk of the car and receives a call from Yero, the outline of Colin Farrell's lav mike, wire and mike head is clearly noticeable through his shirt.
In the opening club scene when Crockett and Tubbs go the roof of 'Mansion', they are clearly on the roof of a building that is downtown Miami ('Bank of America' building in background, etc). 'Mansion' is located on Washington Ave on Miami Beach, not downtown Miami.
When Crockett and Isabella go to Cuba to have mojitos, it is supposedly to La Bodeguita del Medio. The Bodeguita is in a closed-in neighborhood in Havana Vieja on a small street, about 6 blocks from the nearest docks, and with no ocean or highway view. Yet in the bar scene one can clearly make out the ocean and highways. Moreover, the Bodeguita is a tiny place with no outdoor seating, no disco-style dancing, and is mostly a sit-down restaurant with a small bar attached. It is not a "night-life" place.
The topography of Colombia's northernmost peninsula known as Guajira is basically an arid desert, quite different from the jungle backdrop used to describe the smuggler's airplane. This backdrop would most likely fit the Sierra Nevada of Santa Marta, where the "Santa Marta Gold" marijuana is produced.
The aircraft which they are using to transport drugs out of Columbia is an Adam A500. They have been instructed to transport and deliver 1,000 Kg of drugs. However, the Adam A500 has an empty weight of 2,427 kg, and a gross weight of 3,175 kg (gross weight is fully loaded, including passengers / pilot and fuel). So the aircraft they are using is only capable of transporting a weight of 748 Kg, including fuel, passengers, and cargo. It would be impossible for them to transport themselves and 1,000 Kg of drugs on one plane in one load, although it is a pretty cool looking aircraft.
The black Dodge Charger has a SRT badge on the front grill meaning it has a 6.1L V8 engine. On the side quarter panels it say 3.5, which means the car would have a V6. Also the head restraints in the SRT model are stitched and read "SRT 8". This "SRT" doesn't have this on the seats, nor does it have SRT spoiler on the trunk.
When Ricardo is translating the email when they are on the ship, he chooses the origin language as English and the destination language as Spanish. Yet, when he presses translate, it translates from Spanish to English.
During the film's primary shootout, the police are shown bringing in snipers who are located in elevated positions above where the gun battle occurs. Despite having an excellent and unencumbered view (thus the ability to fire accurate shots) and no chance of hitting Crockett or Tubbs, the snipers fire only two times and discontinue their shooting even when the gun battle looks to be turning against the police.
When the Miami PD's speed boats are heading for the final showdown, Crocket's speed boat's running lights are backwards. The left (port) light should be red and the right (starboard) light should be green.
