Continuity mistake: In the first minutes of the movie, one of the cars from the bad guys' infinite supply comes beside the getaway car of the protagonists. Six does what good guys in movies are always able to do; stomps harder on the gas pedal, thus sprinting ahead. We see then the car take a left turn, with the camera positioned behind a bystander with a Ronaldo shirt. But what follows is more shots of the car still driving through the road it supposedly already left (including different natural light in a POV shot). (00:04:15)
Visible crew/equipment: During the rooftop battle, the camera pans left across a bad guy and onto a reflection of two crewmembers in silhouette in the colorful background. Looks like possibly Michael Bay himself (baseball cap, hands clasped behind head). (01:15:23)
Continuity mistake: In the beginning car chase there are several scenes where there is a sunroof above Ryan Reynolds' head. The Alfa Romeo Quadrafolio does not have a sunroof option. Multiple exterior shots of the car show there is indeed no sunroof. However, when they cut back to the interior, there is one.
Other mistake: In China after the pool explodes, everyone is dry.
Continuity mistake: When Rovach is the top of the building choosing new generals, the building they're on is rectangular, however when the generals are thrown over they start falling from the side of a round building (really the Aldar headquarters in Abu Dhabi). (00:56:30)
Continuity mistake: The black BMW chasing the green Alfa crashes, only to miraculously become a Mercedes.
