Continuity: In the scene where Paul is the hotel room, he removes the door slide bolt from the dresser and puts it on the door. He only puts one screw on it and its also positioned awkwardly. In the next shoot, there are two screws on the slide bolt with it placed correctly on the door.
Continuity: In the house full of water, Abuelo forces Paul's head into a filthy toilet. When the toilet is shown in the same scene, it is totally white.
Revealing mistakes: When Paul is trying to escape in the car and hits one of the villagers in the road, the man is yanked back, (by an obvious harness), before the car even touches him.
Revealing mistakes: After Paul hits the man and the car runs off the road, the hubcap comes off the wheel twice... the second time the wire on the cap is clearly visible.
