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. Then in a wider shot from behind them, Jack is a couple of feet off from Nancy, slightly behind her.
