When talking to Marcus on the hospital roof, Mike has handgun put between the trousers and his waistline exactly behind his back, but in the next cut the gun is shifted to the right.
After the helicopter crash -Marcus empties the water out of his left boot twice.
When Judy enters Gatorville with the marshals she is seen wearing two piercings in her left ear. During the confrontation with Armando in her next scene the piercings are missing.
When McGrath frames the banker's lover for the "murder suicide" at the beginning, the bullet holes and blood spatter from when the bodyguard got shot would not fit the narrative at all.
On 1:10:34 Mike said "We got the guy that had captain Howad killed".
In reality the guy who killed captain Howard is Armando.
It was in part three.
Will Smith calls out to Martin Lawrence as "Mike" when following him to the hospital elevator, even though Lawrence's character is actually "Marcus." Will Smith actually tries to say Marcus, he couldn't finish the whole name. In fact you can hear him saying Marc as in Marcus.
When Marcus is on the hospital roof in nothing but a gown, the sign on the adjacent building says that it's a Grand Hyatt hotel. Miami doesn't have a Grand Hyatt, but the one shown is in Atlanta, a sign that most of the movie was filmed there.
The villains are based in a disused theme park called Gatorville. Ludwig says it closed in 2017 as a closeup of its Wikipedia page is shown. The page says the park closed in 2018 but also that it had an albino alligator as its main attraction between 2005 and 2019.
At about 42 minutes into the movie Smith is talking to some other detectives in an office. When the shot shows the back of his head, the shaved hair on the back of his neck is lopsided -- someone didn't give him a proper cut.
When the helicopter hits the water -there are water drops on the camera lens.
At 0:32:49 -drops of liquid on the camera lens.
The movie's finale is set in Islamorada in the Florida Keys, as shown on the nav screen of the helicopter that flew there. The aerial shots of the vast, hilly forests it supposedly contains are obvious fakes: most of Islamorada is less than 1,000 feet wide, and like the rest of Florida, it contains zero natural hills.
It makes no sense for McGrath to work for the cartels after they tortured him. If anything, he should want revenge on them.
At 0:47:46 -since 3/4 inch nylon rope has a minimum breaking strength of about 12,000 pounds it is highly unlikely that Marcus could hold that much weight.
At the 31 minute mark -the shooter puts his firearm inside his jacket and can still shoot the artist.
Not one writer in hollow wood knows what is required to "hot wire" a vehicle.
