Continuity mistake: After the cartoon segment, Deni entertains some playful banter with his girlfriend and takes off, putting a shirt on while he runs. When the neighbour asks him "Late again?", the guitar strap is on opposite sides of the instrument as the editing switches to a reverse shot. (00:06:40)
Continuity mistake: At the start of the film, a man is giving a tour of a building under reconstruction to some potential buyers. One shot, as he's telling them that this sits on a 14-acre lot, there are just 3 people as they walk through a doorway. The film jump cuts to a closer angle, and suddenly a 4th person appears in front of them from thin air. (00:02:34)
Continuity mistake: The protagonist woke up in the lobby, where he went to wait for the return of his daughter and wife. He goes to the receptionist, talks to her, mentions the doctor. She says she'll have the nurse station pass a message. Sam Worthington in the reaction shot has taken both hands off the counter. Cut, and he is waiting and staring at the nurse, but with the right hand on the counter. (00:34:25)
Continuity mistake: After Wesley has intimidated the snot bully, he comes back home and finds the police. Sitting at the table, his mom holds his arm and says "Wesley, Mr. Chambers asked you a question." Mary Elizabeth Winstead has her right arm on the table, close to her body. Change of angle and she is holding the coffee mug instead. (00:45:10)
Continuity mistake: Katie has been grounded, and like most teenagers decides to just drink up a lot of booze. She's sitting on the bedroom floor with her bestie and passes her the bottle of vodka: her friend takes it with her left hand and drinks, but in the following shot she's finishing the gulp by holding it in her right hand instead.
Continuity mistake: When the guy leaves the motel, he only grabs his jacket, but when he's outside, he has a helmet in his hand. (01:14:55)
Revealing mistake: When Anita goes to destroy their getaway car you see her pour gasoline all over the roof and hood. Then when she lights it on fire it's only burning inside the car. (01:06:40)
Continuity mistake: When everyone is leaving the basketball game near the beginning, watch the crowds around the main characters as they walk down the hallway. Sometimes the extras aren't consistent from show to shot. Ex. At one point a black couple brushes past Ryan - the man is on his right and the woman is on his left. When the shot cuts to the opposite angle, suddenly the man is to Ryan's left and the woman is totally missing. This happens a few times throughout the scene.
