Factual error: At the end when Ben Willis and his son have Julie at the graves, Ray shows up with a gun. He fires at Ben but there is no bullet in the chamber. Later after the fight between Ray and Ben's son Julie picks up the six-shot gun and fires 8 shots at Ben.
Other mistake: When Karla and Ty are in the jacuzzi, the "Bob Marley" guy shows up and says they can't be there because it's after midnight. At the same time, the fisherman is killing the hotel's maid who is knocking on doors to clean the rooms. Why in the world does the cleaning lady do the housekeeping after midnight?
Continuity mistake: When Ben falls in the grave his eyes are closed, then the camera cuts and the first or second time it cuts and you can see his eyes sort of open.
Continuity mistake: When Julie is in the confessional, a tear slowly trickles down the center of her left cheek. We then cut to a side shot and the tear has moved next to her nose. (00:02:50)
Continuity mistake: Before Julie gets her knife and cuts Will with it, the camera zooms out and you can see her go for the knife and not get it, so they make you think she actually is supposed to go for it the second time. (01:24:00)
