Continuity mistake: Lucy goes up to Max, taunting him and he snarls at her. In this shot the chain holding his right arm is tight against the wall like usual. But in the next shot as Lucy is backing up with her pistol, there is lots of slack in the chain with it resting along the ground. It's tight against the wall again holding him in the next shots.

Continuity mistake: When Baca's Hummer starts throwing up steam and smoke from the engine, they slow down to stop and get out to check it out. As they are slowing down and coming to a stop, the camera shows a view from inside looking out the front windshield and there is a guard rail on the side of the rode that is right next to them as they stop. When the camera changes angles to outside as Baca opens the door, the guard rail is suddenly at least a good 5 or 6 car lengths behind them. (00:23:30)
Continuity mistake: After the crew inside the second Hummer talk about the foods they miss, it shows a shot of them going around a turn with the rear Hummer in the lane over and with the front Hummer half covered in shadows from the trees. In the next close up just before the lead Hummer starts to smoke, it is suddenly fully in the sun and the rear Hummer is suddenly right behind it. (00:23:20)
Continuity mistake: Zoe and her friend are walking out of the medical training room at the start and she has her phone/ipod in her hands. In the next shot in a close up, she's suddenly putting her hands in her pockets. (00:04:35)
