Continuity mistake: When Abby slaughters the bullies, we see most of the scene from Owen's underwater point of view. First, a decapitated head floats down, leaving a trail of blood. Then, more dismembered bodies splash into the water. We get the sense that the pool water around Owen should be pretty bloody. Yet, when he surfaces, the water around him is completely clear, with no evidence of any blood or bodies.
Continuity mistake: In the final battle scene after the Band reaches the canyons and are on a cliff overlooking the Guardians, you can obviously see that Twilight doesn't have his lute. After focusing on Soren struggling to remove the pot of tar, we see Twilight flying with Digger and Gylfie, but with his lute. Impossible to be so fast. (01:11:55)
Continuity mistake: In the first scene with Lucas in the race car, a curly also wants to get in it, but he is smashed to the ground by the driver who puts a brake. First we saw a lot of blood dropped from his head (on the starting grid), and in the next scene, shot with another camera, the blood disappears.
Continuity mistake: When Becky is having lunch in the park with her workmates, they all turn to look at Adam and the blonde workmate is holding her drink in the air. In the next shot, however, the drink is flat on the table, with no time to change.
Continuity mistake: In the scene where Cindy is about to have her abortion, we see a shot of the nurse holding her hand and the nurse has on purple latex gloves. In the next shot, the nurse is holding her hand without gloves.
Continuity mistake: When they jump on the train at the end of the film, the train tail light is on the right hand side and its also a light that didn't come in until the 80's and in the long shot of the train speeding along the tail light is on the left hand side.
Continuity mistake: When Brown is talking to Michies Mother about the Final jam, Brown goes round to his desk. If you look at the computer when he does this, it is pointing slightly to the left. Then he goes round to the front of the desk and the computer is pointing to the right before anyone has the chance to move it.
Continuity mistake: First when Carson kisses Rachel she's on his left side. When the kiss is over she's suddenly on his right side. (00:52:00)
Continuity mistake: When Marie dinners with Didier for the last time, the girl behind has either her hands on the table or grabbing the menu, depending on the angle.
Continuity mistake: When Ellie & Fiona are breaking into the garage to steal the gas tanker truck, Fiona's hands are by her side. The camera angle changes, and her right hand is up, holding her rifle strap.
Continuity mistake: When the security guard opens the back of his vehicle the gun is pointing to the left, but when the shot changes as the security guard reaches in for the hat, the gun is pointing to the right. Then as he turns to put the hat on Tyler, the gun is again pointing to the left.
Continuity mistake: Towards the end of the movie, after Boyka gets out of the car with the briefcase, Turbo gets out after him and has a conversation. When Turbo goes back to the car, you see Boyka standing on the side of the road. There is only that one road in all the shots. In the next close up shot of the car door closing, and the car moving, we see the car getting out on to the road from a small by-lane (of sorts)! Where did this road come from? How did the car move places?
Continuity mistake: At the end of the movie, when Ray makes a call to channel one news, he is seen to press the dial button, but when he looks to see a fleet of super hybrids, his phone is displaying a picture rather than placing a call.
Continuity mistake: When the crazy 8 go for their first night swim, they are dry when they get to the chapel on the way back, yet when they get into their dorm, they are semi-wet.
Continuity mistake: At the end of the movie, when Robert has been resurrected as a tricycle, the bell and ribbon keep moving back and forth from the right handle bar to the left one.
Continuity mistake: During the last scene, the strands of hair that Edgar has running down his face/right cheek are over the top of his head during some shots. Edgar is holding a book between both hands, so not moving the strands himself. (01:16:19 - 01:16:55)
Continuity mistake: Near the end, the orderly restrains Kristen and the doctor says not to drug them. The doctor is holding Kristen by the arms. However in the close up of her getting the injection her arms are free, only to be restrained again in the next shot.
Continuity mistake: During the "bedroom scene", Dana suddenly had wrist chains on for a short period of time. Before this, a chain could be seen dangling along the wall near the bed, but the chain was never seen going onto the bed. The same is true for the chain attached on the other side of the bed. (00:02:50)
Continuity mistake: The little Nono is singing the nursery rhyme in front of the cafè. One of the nazis tosses him a coin, while the other puts the cigarette down, but at the cut he's already taking a puff.
Continuity mistake: After the shootout at Sarah's birthday party, White Mike is visited at the hospital by Molly. Mike's pillow has marking "Property of Queens Hospital", they cut to Molly, then back to Mike, and the marking is gone.
