Continuity mistake: When we first see Hobbs he is marking a load of paperwork as captured. On the first sheet, he punches "captured" directly on the photo. In the next shot the word "captured" has changed its position on the photo. (00:09:35)
Continuity mistake: In the final chase, we see Max taking the arrow out of his hand and Furiosa pulling the knife out of herself. A few shots later, Furiosa is changing gears and moving the rig to the left of Max's rig. In that shot, the knife is still lodged in her body. (01:39:40)
Continuity mistake: After Noah's creepy "it got pretty wet here this weekend" joke at the family dinner table, Jennifer Lopez holds her tray in a complete different way between shots, multiple times depending on the angle. (00:29:00)
Continuity mistake: As Jake and Olivia steal a car while their enemies are shooting at them, we see a rear-view mirror. A few seconds later, Jake turns to check if they are followed, and the mirror has vanished. As they reach the safe house the mirror is back. (00:19:55 - 00:21:30)
Revealing mistake: When Benji imagines putting on a mask of an agent he plans to impersonate, when the camera pans around to first show the mirror, the mirror Benji's hands are further up on his face than the reflection, and the mirror Benji's hands move down his face slightly before the reflection starts to move them. Also, the mole that Ethan has on his left cheek isn't reversed in the mirror image. The "mirror" was actually a hole in the wall between two identical sets (one mirrored), with Simon Pegg and a Tom Cruise double in the foreground, and the mask actor and Tom Cruise in the background "mirror" set.

Character mistake: At the truck stop, Mark (young Damian) meets with Martin. Martin tells Mark that he had the shedding pills reverse engineered and hands him a piece of paper. The percentages of the 5 ingredients only add up to 90% rather than 100%. (01:29:25)
Continuity mistake: Nicholas Cage sees his ghostly son through the window of a bus, and so he rushes after him. Right at the first left turn, the natural light couldn't be any more different in the two separate shots. (00:32:30)
