Continuity mistake: When Ree visits a girl holding a baby, when she's about to leave the baby's hat swaps from off to on between shots.
Character mistake: Throughout the film, the characters refers to the seigneurie as Beaufort or Beaupré, which are actually two different places.
Continuity mistake: During the last fight with Darkseid, there's changes to what the farm looks like. At one point, instead of the windmill there's a building, which we never saw when Clark drove past the spot. And the overturned truck is missing in a several of scenes even though it should be visible.
Continuity mistake: After Rita and Eddie's fridge is repossessed they are arguing outside their flat. On the wall outside their neighbours' flat there is a wheeled trolley or pushchair hanging on the wall. This disappears and then reappears several times during this sequence of the film.
Revealing mistake: In the final scene we see a bomb disposal technician disarming a nuclear bomb. The screen of the laptop is shown in one brief shot. It displays a database program of some sort, and has been filled in, perhaps to look like it contains lots of helpful, bomb disarming related information. However, it is actually just random button mashing; most of the 'codes' consist of the letters 'dfgty'. Look at where they are on the keyboard. Very lazy: dgght dfhdftyh fghrthy.
Continuity mistake: In the scene where Beau and Chiles are in the hotel room, with Canter knocking on the door, Chiles puts on her shirt twice.
Continuity mistake: Neither Abra, Betty or her kids age a single bit in a time span of 20 years.
Revealing mistake: In the scene where Rachel McAdams goes to Patrick Wilson's office to explain why she left the bar so abruptly the night before, there are four TV monitors behind her as she does those weird charade movements. Only one monitor has a picture. The picture is of the New Jersey anchors of the job from which she was previously fired. Also, the characters in the picture never move.
Continuity mistake: After Dave stabs Ravi, the shot cuts to Kurtis running through the woods trying to escape. Ravi (in the clown costume) is seen among the ones pursuing him, but he's either dead or dying at this point, and, obviously, cannot chase someone while riding an ATV. It's a recycled shot from when Tommy was attempting to escape.
Suggested correction: It isn't Ravi on the ATV. Towards the beginning you see Dane on the stairs talking to 3 students, a little later on in the cafeteria you see the same 3 students sitting at a table and the shots keep switching between them and Dane and his friends, and Dane says something like "and they will be in the woods dressed in the same outfits/costumes as us." It's meant to confuse the cops when they show up.
Continuity mistake: The sweat stains on the phone costume keep changing when in the police station. (00:12:00)
Continuity mistake: In electric avenue scene, the number of wood bars the cast has to go around changes from two to four.
Factual error: A fire breaks out in the hospital due to one of Abby's victims being exposed to sunlight as she's turning into a vampire, destroying that vampire and a burning a nurse to death. Modern hospitals have fire sprinklers, fire extinguishers, etc. and sensors/alarms that the fire would have activated.
Continuity mistake: When Wally is talking to Sebastian in his bed, the latter has lost two of his bottom teeth. For most of the rest of the movie they are there. In the last scene they are gone again.
Factual error: In the scene where they are in the U.K, a little boy is hit by a van and you can hear the police and medical services coming. The sirens are American sirens which differ greatly from the High Low pitch that the U.k Is famous for and do not fit the scene at all.
Continuity mistake: Carrie's skateboard is broken in half after she sneaks off with Flicka to ride it in the city. Later, when she's sitting on the couch depressed about Flicka being gone, the skateboard is in perfect condition. Adding to this is when she gets a new board near the end of the movie. (00:58:00 - 01:14:00)
Factual error: When they are watching the prince's wedding on TV, you can see the TV-channel's logo in the corner of the screen. The channel NRK didn't start using this logo until 1996, so the program is definitely a rerun, and not the original airing from 1968 which is when this film is set.
Deliberate mistake: At the beginning of the movie while driving through town the old rusty horse trailer was facing from left to right. at the end of the movie as they were leaving town, they showed the same trailer and the picture was inverted, parked in same location,however it was facing right to left.
Deliberate mistake: When Jared is picked up at the airport in the limo, after the scene where the limo is driving down the interstate it cuts to a shot of several tall buildings. In the street at the bottom of the shot, the traffic is moving backwards if you watch the facing of the vehicles. Looks as if the film plates were flipped. (00:06:30)
Revealing mistake: Throughout the film the actors' breath is visible. This wouldn't be happening during the summer when the film is set.
Continuity mistake: In Joanna's bridal shower she gives a necklace to Marni. When Marni is talking to her nanny the necklace disappear between shots.
