Continuity mistake: When Grace is sitting at the edge of the cliff, talking to Bobby, in the wideshots you can see that there is no gun next to Jake on the rocks. The gun then appears when Bobby looks over at Jake and notices it. (01:50:40 - 01:51:50)
Revealing mistake: After Grace pushes Bobby off of the cliff, in some shot's the Sheriff's dead body breathes. (01:51:45)
Visible crew/equipment: Crew reflected clearly in Grace's eyes, along with camera, in an extreme closeup after she shoots Bobby. (01:53:45)
Continuity mistake: When Bobby strangles Grace to death, after strangling her, you can see Grace's arm by her side, yet in the following overhead wideshot both her arms are far out away from her side. (01:53:55)
Continuity mistake: Jake's arm changes position while he is lying dead at the bottom of the cliff. (01:54:00 - 01:56:20)
Visible crew/equipment: Man with a cap on, reflected in the triangular window when Grace is in the car. (01:54:40)
Visible crew/equipment: When Bobby is telling Grace he can't move and that she will have to come down, in a closeup of her eyes 2 or more people are reflected in them. (01:58:25)
Continuity mistake: Grace's legs change position while she is lying dead at the bottom of the cliff. (01:58:50 - 02:00:40)
Revealing mistake: After the radiator hose breaks for the last time, Bobby opens his mouth to laugh and it is obvious that the teeth that are supposed to be missing have just been blacked out because he touches them with his tongue. (02:00:15)
Continuity mistake: Between shots Grace goes from walking backwards to forwards, when meeting Bobby for the second time.
Continuity mistake: When Bobby is arguing with Darrell, there are four red round sponge marks on the right wing of Bobby's car. As we change to Darell's POV, just after the close up of the 'for sale' sign, followed by Darrell telling Booby to leave 'before I call the sheriff who knows me', there is only one red round mark.
