Griffen is wearing a yellow t-shirt when the girls are in the police station, but when they leave and have a discussion on the steps he is wearing a green t-shirt and a green shirt. The t-shirt changes back to yellow when they are on the boat, but when they get to the police station for a second time he is back in green. All this is supposed to be the same day.
When the twins are walking up the beach after getting off of the sea-doos, Madison is wearing a life jacket in the first shot. The camera switches to Griffen, in which Madison's reflection can be seen in his eyes, and she is still wearing the life jacket. One second later, the camera goes back to Madison, and the life jacket has been removed.
When the girls find the hidden antiquities on the boat, there is a crew-member standing in the doorway behind Alex, and another person wearing white walking behind the first man.
Near the end the girls are searching the bedroom on the boat. When one of them looks under the end of the bed a cameraman's bare toes are briefly visible at the bottom of the frame.
