In the opening scene, the character of Molly Graves dives into the water wearing a black two piece bikini. When cutting to the shot of her swimming underwater she now also has a purple robe on.

When Robert Graves shoots the sheriff, the sheriff falls back against his police vehicle, and the gunshot wound cannot be seen from the front where he had been shot. In the next cut, the wound is clearly visible on the sheriff's back.
