Continuity mistake: At the end, when Gloria hurls Oscar completely out of sight beyond the horizon, a huge crowd of South Koreans rush up directly behind Gloria, cheering and applauding, only a few feet away from her. The camera cuts to a frontal shot of Gloria, and now the crowd is 30 feet or more in the background.
Revealing mistake: Despite Sigourney Weaver supposedly having had her fingers cut off if you watch her when she's in her straitjacket you can see her fingers moving around.
Continuity mistake: When Sasaki is showing Sook-Hee through the mansion, Sook-Hee begins walking up a few steps. The camera changes to a different angle where Sook-Hee has suddenly rotated 90° to her right to face the stairs in front of her. (00:05:30)
Continuity mistake: When Michelle gets catapulted onto the wall and begins wailing, her right arm is straight, semi-parallel to her shoulders. Next shot and it is bent, hand up to the level of her face. (00:22:55)
Continuity mistake: When Gina and James visit her sister, Gina sits down at the table with the family. Then in a close up with James and Ramon, Gina walks into the same room she should already be sitting in. (00:48:30)
Continuity mistake: After the credits, Tom Hopper sees and hears a bunch of helicopters and calmly walks indoors. He then addresses the waiter raising his left hand before the cut. In the next wide shot though we see him with a right hand raised that reaches for the champagne tray and grabs a glass. He says "Thank you" in a third shot, same angle as the first one, and in fact, the champagne flute is in his left hand now. (00:02:50)
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.
Other mistake: When Bill is alone with the girl at his house, there is a roaring fire, but in the next scene the fire is completely out and he comments, "you must be cold, I didn't have time to start a fire".
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.
Continuity mistake: The old man in the hotel lobby pulls the flowers out of the megaphone and calls the protagonist. She lowers the headset to talk to him. The left speaker is all the way across the opposite side of the neck in the first shot, less shifted to that side in close-up. (00:04:00)
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)
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: At the toll booth, Afonso does a thumb up sign to the operator, not knowing what he really said to his son about their ride. He is doing the gesture with his right hand, left hand, right hand again depending on the shot. (00:07:00)
Continuity mistake: In the first scene, the old alien man comes to pick up his spaceship and Ratchet instructs him to "Now, let's fire up that mag booster." The old alien pushes the switch forward to start the mag booster. Later in the movie, Ratchet flips the switch backwards to "engage mag booster" as Clank commands. (00:06:30 - 00:26:30)
Continuity mistake: Mikey dropped the wristwatch Andrew gave him and it landed face down with the bands upward. When Mikey jumped off the rock to retrieve it, the watch's face was on its side (visible to the screen) and the bands were parallel to the ground. (00:05:04)
Revealing mistake: When the Creature is telling Louis the "Bat Story," the Creature is holding a burning torch in its right hand against a wholly-dark background. It becomes apparent that the shots of the creature are actually Dutch Angle shots (the angle of the camera is rotated about 45°), because the smoke from the torch is not rising straight upwards; rather, the smoke is rising at a 45° angle toward the upper left corner of the screen.
Other mistake: The tow truck driver says he has to repair the "split axle" before they can proceed. It wasn't clear what kind of truck he arrived in but the car could easily have been towed on the rear wheels on a wrecker and winched onto a flatbed.
Continuity mistake: The gang Bo is reluctantly part of gets to Maurice's crib where he is playing cards with his homies. The red jacketed one is defiant, and grabs a handful of red and blue chips in front of him tossing them in Angelo's face. But if you check out of the table in the wide shots before this occurs, you'll notice that red chips were never in the stack in front of him to begin with. (00:19:05)
Continuity mistake: In the 3 wheeled vehicle, Bennie is driving and Conner says "Women do not go for that whole constipated Debbie Downer look." A shot shows Bennie's hair blowing wildly in the wind, then cuts to a view from Conner and suddenly Bennie's hair is straight and still, then cuts again and once again his hair is blowing. (00:39:45)
