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: Nicholas Cage is stapling the posters with his missing child (strangely enough, all the concert posters are in terrible condition even if they advertise events that happen exactly when the movie takes place). He hears his son's voice and turns around, the wind flips the poster on his hand. When he turns back to it, the poster is gone (but he still has one to attach). (00:27:00)
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: After reviving Ethan after escaping from the water tank, IIsa's bra strap is visible under her tank top. When she changes later, the bra disappears. (01:10:00)
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: Jake and Olivia leave their broken car near the woods. The windshield wipers are in the upper position and the driver's door is opened. As the bad guys arrive, the windshield wipers are in the lower position and the door is closed. Then they come close to the car, the windshield wipers are a bit higher and the door is wide open.
