Character mistake: A shot shows Djimon Hounsou completing his year entry on a large chalk board. The entries are 20 years apart. The third entry on the second line is 2274, the next should be 2294, but instead it records 2394. The one after corrects the sequence with 2314. Considering there is an entry only every twenty years, you would think he'd be more careful. (00:20:15)
Continuity mistake: When Theresa and Ben walk down the road leaving town, and run into the woods from the Sheriff, Theresa's roller suitcase falls over on its 'back'. A minute later, when Ethan catches up to them, the suitcase is on its 'front'. (00:36:30 - 00:37:30)
