Continuity mistake: When Kirk Lazarus tricks Tugg Speedman into giving him the map, in one shot one of the shotgun shells on his back in his artillery belt is out of place and not lined up with the rest of them. In the very next shot, all the shotgun shells are lined up and in place evenly. (00:44:05)
Visible crew/equipment: When Max meets a man in a car who invites him to jump in, they go to the place where Natasha was killed. When the car drives in the alley and we see it from the top of the building (the camera angle), the camera filming them is visible in the reflection on the car's roof (it's mounted on a rod hanging high above the alley). (00:18:25)
Continuity mistake: When Mutt slams his fist on the table in the diner, the ketchup and mustard bottles fall over. When the shot pans to Indiana's back, the bottles are standing up again. He then tells Mutt to sit down and the camera pans back to Mutt. The bottles are lying down again and Indiana picks them both up.
