Character mistake: When Katie's husband arrives in town and confronts her on the night of July 4th, he says "I miss you Katie." He does not know her name to be Katie as that is the name she created when she came to town. He is married to Erin.
Suggested correction: He says "I miss you, baby" and then "I miss you so much, baby."
Revealing mistake: In the scene where Josh Duhamel and Julianne Hough are in the row boat, it starts to rain so they rush to shore. They huddle under a tree and you can see behind them that the rain is only falling right around them - only slightly further away on the lake there are no rain drops hitting the water.
Other mistake: When the husband breaks into the old lady's house and checks her voicemail, it says that Katie left a voicemail Monday at 11:47am. When the husband calls the restaurant, the recording says they are open from Tuesday to Sunday. So Katie shouldn't have been at work.
Factual error: When David Lyons checks the map on his computer where it shows where you can travel with Coach America, it shows all stops and routes. But Southport isn't a stop or on a route. Closest stop is Wilmington. (00:17:43)
