Continuity mistake: After Adam Westinghouse catches up to the main characters, he fires up into the air and threatens to shoot them in the back if they don't stop. They turn to face Adam and Lucas is holding his BB gun in his left hand. The camera cuts to a different angle and suddenly Lucas is holding the BB gun with both hands but in a right handed hold. And he is also a little bit closer to Noah. (01:21:45)
Continuity mistake: When Noah enters the first house, a man wearing a black boggan on his head turns to look at him. Close to him is an old woman sitting on a couch watching TV. In the this shot, her shadow on the wall is slightly elongated and thin. But it cuts to a different angle and you can tell they moved the lighting around for the shot as then her shadow is roughly the same shape and size as her and much dark and thicker. (00:03:20)
