Continuity mistake: When Agents Mackelway and Charelton are driving to the scene where there is a murder victim in a car hanging at the edge of a cliff, we can see the dust trail from the car begin about 50 yards up the dirt road. With as little wind as there was in this scene, we should be able to see dust all the way up the road. Also, when they start talking with the local sheriff there is a very noticeable cloud of dust behind them, there is a brief cut away, then the dust cloud is totally gone.
Continuity mistake: After Jack and Nancy leave the Allison boat and are returning to shore, just as they are watching their stolen car being towed from the shore, there is a shot in front of them and Nancy is snuggled up close to Jack, slightly behind him.
