Continuity mistake: The main character is chatting with Harper at the shooting range. Harper's earbuds and protective goggles change position between shots throughout the scene. (00:08:50)
Revealing mistake: Right after the little girl sprays the monster with bug spray, you can see the costume of the monster, it's wearing a black cap. (01:19:00)
Continuity mistake: Maggie asks her mother about the book she just started; she replies in a reverse shot where Maggie is suddenly drinking a glass of wine. (00:04:10)
Continuity mistake: When Kurt and Kavi are washing clothes, the clothes change position on the line, specifically the red shirt at the end and the shorts Kavi hangs up. The red shirt is twisted around the line, but in the shot of Kavi hanging the shorts, the shirt is hanging perfectly straight down.
Continuity mistake: The crew arrived at the volcanic island in turmoil, and are talking with the local captain. The captain asks them to carry also some of the dead people, and they start asking him what the plan is, if there's one at all. The pass at the neck of the captain shows the side with the symbol in one shot, the blank one in the next. (00:25:10)
Continuity mistake: Maureen spent the first night in the spooky house, without conclusive results. They are meeting the prospect buyers in a bar. When Lara walks up to them and begins the conversation, the arm position of the man changes wildly between shots several times at every cut. (00:08:40)
Continuity mistake: The chef at the airport stabs someone, but the knife blade is clean afterwards; moments later he stabs it through the valise, and it is covered in blood.
Revealing mistake: Set in Pittsburgh, PA, scenes were obviously filmed out of sequence. Many scenes were "out of sync" with the snowfall, whether in progress or amount (if any) already accumulated. For example, there was no snow downtown, but views from the helicopter showed snow-cover around the nearby parkway (Route 376). In another scene, it was snowing when Ryan turned his Jeep into a downtown road that was covered with at least one inch of snow; switching to a "live" newscast, the sun was shining outside.
Continuity mistake: Walter tore out the newspaper article ("Body of Woman Found at Greenland Rest Stop") fairly neatly/evenly; it was relatively straight across the top, though a little jagged as could be expected. When Walter looked at the article some time later, the jagged top was worse and there was MORE space between it and the title. The right side also appeared to be more jagged than it was and include a little more of the article that was to its right before being torn off. (00:07:03 - 00:13:37)
Continuity mistake: The bullies spray-paint the lead girl's bike pink, yet in the next scene, it's getting spray-painted again.
Factual error: When Joe and his girlfriend, who is also Albert White's mistress, walk through the hotel room kitchen, that whole kitchen, is not a 30's era kitchen. It even has a convection oven and a blast chiller, pan racks, etc. that are more from this time.
Continuity mistake: After their fight with the monkey Sara has some scratches on her forehead and cheekbone but when she gets to the castle with Freya they are gone.
Factual error: In the Templehoff Airport flyover scene there are Soviet era Antonov An-12 propeller driven aircraft on the tarmac. These were first used by the Soviets in 1953.
Continuity mistake: When Lady Susan is counseling her daughter Frederica in her bedroom, the shot shows an unlit candle on a dresser behind Lady Susan. The shot changes back and forth between Frederica and Lady Susan. When the shot changes back to Lady Susan, the unlit candle is gone, though there is no one else in the room.
Continuity mistake: When they are at Sarah's house, the boy's father tells her to go outside and ask Lucas to pull the van around back. When Sarah walks to talk to Lucas her long braided hair is tucked into her shirt and her arms are crossed. In the next shot when the camera comes back, her hair is on the outside of her shirt despite her arms still being crossed. (00:45:55)
Factual error: Viggo is "playing" the bagpipes on the wrong side. They should be under his left arm, not his right. He is also not blowing hard enough to make the required sound. They sound good, though.
Factual error: In the wedding and arrest scene the U.S. Customs Service officials have police attack dogs. The U.S. Customs Service only has drug detection dogs. (01:57:00)
Audio problem: The chef finally gets the bright idea to fire his hunting rifle at Morgan's fleeing vehicle. In a previous scene he was grabbing ammunition for his rifle, and he also loaded it. The rounds appeared to be high power rifle ammo, probably in the 7mm Remington magnum or .30-06 range, very common hunting rounds. When he fires his rifle it sounds quieter than a suppressed shot, however he has no suppressor on the muzzle end of his weapon. (01:09:20)
Factual error: When Steve Carell is telling his nephew Jesse Eisenberg that he is leaving his wife, the view from his 1930s era Hollywood Hills home shows the modern skyscraper-filled LA downtown skyline.
Factual error: During the scene when Ed the I.T. guy is working on his laptop to fix the problem with the presentation, his laptop is sitting on top of a couple of Cisco network switches with cables connected to them. The ports on the front of the switch where the cables are plugged in would have flashing lights on to show power and connectivity, as well as lights on the left-hand side of the device as we are looking at it, no lights are present which suggests it is not powered up and connected to anything.
