Continuity mistake: When Ray returns to the Pit Stop in a police cruiser, the car is parked under the Pit Stop sign, but in the next shot, the cruiser is far from the sign.
Continuity mistake: Ray is speeding on the road that he previously traveled very cautiously. He is engaged in a tricky overtaking of 4 vehicles in a row. In the side view close-up he is overtaking the sedan, but after the close-up on the speed meter that is going past 80, he has yet to pass that same car, since the car before that was a SUV.

Continuity mistake: Peri is at the edge of the excavation. In the view from behind the dog (just after her dad reaches down for the rock) her right braid is on the lapel of the coat, while it was all on the outside of the collar earlier. (00:10:25)
Continuity mistake: Ray is sitting in the lobby with his wife. She is stroking the face of her daughter with her left hand, but the hand is not there in the close-ups. (00:18:25)
Continuity mistake: Peri is being visited by the nice Dr. Berthram. The stethoscope tube passes between shots from outside the collar of the shirt, to inside. (00:24:40)
Continuity mistake: The protagonist woke up in the lobby, where he went to wait for the return of his daughter and wife. He goes to the receptionist, talks to her, mentions the doctor. She says she'll have the nurse station pass a message. Sam Worthington in the reaction shot has taken both hands off the counter. Cut, and he is waiting and staring at the nurse, but with the right hand on the counter. (00:34:25)
