Factual error: Their 'spot' for drinking is apparently in the French Quarter because of the street signs. That said, they are drinking Budvar beer. If you know about Budvar, it is the original Budweiser beer from the Czech Republic. Budweiser sued Budvar and won, preventing them from using the name 'Budweiser', even though Adolph Busch came up with 'Budweiser' after going to Pilsner, Czechoslovakia. Budweiser being the bully, and their lawyers and all, won the lawsuit. So now the beer is sold as 'Czechvar' in the US and 'Budvar' everywhere else, meaning they couldn't be drinking it in the USA.
Factual error: It is not possible that Pitt could have gone up to the ship when it was already blasting off. There was literally fire in the tunnel.
Suggested correction: It was a bit confusing, but what I saw was a shower of sparks or hot particles and some fumes, and no fire in the tunnel until he was through the hatch. The makers may have been influenced by seeing vapour prior to a rocket launch, and then some rockets use a shower of electric sparks to ignite the engines. It was implausible, but no fire in the tunnel.
Continuity mistake: Mr. Furlong pushes Zeke into the fishing tank and it breaks, soaking him from head to toe with water. Moments later they are walking out and he is dry.
Continuity mistake: On the ship, Dr. Zimsky reveals that project DESTINI is an acronym and that the last letter is "I" and not "Y." (INI standing for INItiative). When Rat is at his computer, he goes to the website for Project Destiny, with a "Y" and not an "I." This same thing happens when the Project Destiny subtitle flashes across the screen.
Continuity mistake: Daniels' face gets splattered with blood, in a following shot there's slightly less blood, then when she uses the radio to call back the others, her face on the screen shows no blood at all. In the other shots after it's there again.
Continuity mistake: When Nick is sitting on the bed talking to Jessica, her position changes from lying on her side to lying on her back, as the camera angle changes.
Visible crew/equipment: When Dennis Weaver is in the cafe a shadow of a cameraman is cast across the table he is sitting at. The shot then changes to a wider angle to reveal that there isn't anyone near him who could have cast that shadow.
Continuity mistake: Before Tony leaves he closes the drapes. He then says he won't go out and will stay home. She says to go out, and he agrees, so he goes to the drapes and closes them again.
Factual error: Mel and Goldie board a ferry. A visible sign states 'Detroit-Racine Ferry'. Detroit is on the east side of the state of Michigan but Racine, Wisconsin is west of Michigan, across Lake Michigan. The only water route to get from Detroit to Racine would be to circumnavigate the entire state of Michigan.
Revealing mistake: When Han shoots at Bruce Willis and the others with the Gatling gun, we see cartridges on the ground. You can tell that they are all blanks. The tip is jagged and has been closed - live ammo just has an open hole where the bullet was.
Revealing mistake: On the ice the tank is firing - in slow motion we see empty shells are littering the area. The shells have crimped ends, revealing them to be blanks.
Factual error: The movie takes place during the 1990s, but throughout the movie cars are shown with Illinois license plates with "Illinois" written in cursive. These plates were not introduced until 2001. (00:24:45)
Revealing mistake: When the kids are burying Gus, his supposedly dead face flinches when they shovel dirt on him.
Factual error: When Swagger is fleeing from the police in the car wash after being shot, the radio says that he is at a car wash at 9th and Girard. There is no such intersection. On Girard Ave, 9th street picks up south and north of that street.
Continuity mistake: When the police are moving in to arrest Dzhokhar Tsarnaev, the shot shows an FBI SWAT officer grabbing him. But in the next cut, the officer changes to a Boston Police Officer while changing back to a FBI Officer in the following shot.
Continuity mistake: When Fox and Wesley first jump off the building onto the moving train, Fox has on boots with heels, but when she lands on the top of the train, her boots are flats.
Revealing mistake: Before Paxton is hit with the 3 prong instrument, you can see the bloody holes already on his shirt. (01:01:20)
Continuity mistake: When surrounded by police and a garbage truck, Frank drives his car from the overpass onto the passing transport trailer below, then lands behind a hatchback and in front of two cars - a white compact with a sunroof and a grey hatchback. In one specific shot from atop the trailer, as Frank rolls his window down (before he requests the gun) the only vehicle behind Frank's car is the white compact, which is at the trailer's rear. Note things such as the trailer's safety bars, and the view through the compact's windshield for starters. That grey hatchback is back when the ramp is lowered, for the ensuing crashes. (00:08:20)
Visible crew/equipment: At Hoover Dam, after the salute, when Defense Secretary Keller speaks with Lennox and Epps, the reflection of the white reflector screen is visible on Keller's glasses. What's more, the boom mic's reflection is actually visible within the reflector screen's reflection. Two for the price of one. (01:35:30)
Factual error: In the big battle scene at the Home Mart store after Robert turns the power off to the building, you see Robert grabbing welding canisters. When Robert has Ralphie turn the power back on, it cuts to one of the bad guys in the break-room, and a digital microwave starts counting down. A digital microwave could not have any memory of any prior cook settings, let alone any way to set it, since the power was already out. (01:55:40 - 01:56:35)
