Continuity mistake: While eating dinner, Lauren has a glass of wine setting on a black coaster. After a scene change and return to the dinner table, an aerial view shows the coaster without the wine glass on it (and the wine glass is missing from the table). (00:38:32 - 00:40:18)
Continuity mistake: The pile of clothes Lea took out of the dryer and placed on the table were rearranged differently when the camera shifted to the opposite side. (00:41:52)
Continuity mistake: At the Internet Store, Spencer was told his house was "right outside" the service area, internet was not available, and a satellite would not work. At the Phone Store, Chad told Lynn and Zoe they were in the "dead zone." When Lynn answered Spencer's call by putting her head out the upstairs window, she said, "The service is great up here." Lynn and Zoe could listen to the news on their cell phone in the kitchen and Zoe read about asteroids just outside the front door. Internet worked? (00:04:53 - 00:28:00)
Continuity mistake: In the opening scene, the players are taking their third card of the hand before the dealer reveals their second card. (00:02:40 - 00:03:15)
Suggested correction: That's not what happened. It was a montage scene. It's not 3 different players, it's the same player and 3 different hands. Notice the card is always dealt to the same spot.
Continuity mistake: Toward the end of the film, Hannah, who has had her face pummelled by one of the villains emerges from the creek having escaped the fire with only minor bruising on her face and a cut on the bridge of her nose. Immediately after that, they are rescued but her face is now deeply cut, both eyes are blackened and there is a deep gash on her cheek.
Continuity mistake: The appearance of young JR's hair has many inconsistencies. For example, JR's parted bangs (on the left) are long enough to hang part-way into his right eyebrow while he is walking toward the bedroom, but his bangs are well above his eyebrow when he is standing in the bedroom doorway. When JR is in bed that night, his bangs are separated along the right side of his forehead, but neatly combed together (no gaps) after a camera shift and contrary to gravity. (00:05:10)
