Continuity mistake: When Bucum is in the trailer at the beginning of the film, and the woman starts shooting at him with a shotgun, he runs and dives through a window. Before he dived through the window he had his pistol drawn. But when he's flying through the window, you can see it in the holster on his leg.
Visible crew/equipment: When the two diamond robbers get out of the black van and into their Mercedes and drive away, you can see the camera reflected on the top of their car. The camera cuts to a view from above the vehicle looking in through the sunroof, then when they drive away, the camera is visible in the reflection.
Plot hole: When they were on the boat fighting, the girl that got shot in the head would be moving instead of just lying there.
