Continuity mistake: The positions of the two black SUVs relative to the driveway and garage are different when Justin is reviewing the recording and looks at images from opposite sides. In the first view, the SUVs are not pulled up close to the garage doors; the garage is at least a car's length away because it is not visible to the left of the screen. In the second (opposite) view, the SUVs are parked close to the garage and the SUV that is supposed to be parked near the corner of the driveway is further away. (00:25:30)
Continuity mistake: The angle/position of Katie's fork near the corner of the table varies, even though she has her hands on her lap or folded on the opposite side of her plate. (00:03:04 - 00:04:30)
Revealing mistake: This happens in the second ceremony when Wolf didn't press the button to shut off the lights to steal the golden dolphin because of the good comments. Few seconds later, the lights shut off, and you can see that the meteor on the top disappears at the time.
Continuity mistake: While driving to Harper's house, Jordan did not have the sun visor down, but it was down when she was backing up after she passed Harper's house, #237. The sun visor was not down when Jordan was going down the driveway to the house. (00:17:15)
Other mistake: Food products used for a snowman's eyes, nose, and mouth (olives, cucumber, and ketchup, respectively) do not stay intact or unchanged over a 1-2 day period, if at all. [The idea is too absurd to categorize as a "deliberate mistake."] (00:48:33 - 00:57:00)
Other mistake: The GPS voice said, "Your destination is on your left", but Kath kept driving (slowly) on the dirt road and did not reach the cabin for over 30 seconds (longer than would be expected). A GPS system typically announces how many feet until you reach your destination, plus "You have reached your destination" after traveling that number of feet. (00:05:00 - 00:05:38)
Character mistake: We see the lead driving on the motorway to get to the cottage. She leaves at junction 6 for Princes Risborough. Which means she is on the M40 that goes to Birmingham. When she arrives the host asks about the drive down and mentions the M4. This is a different road entirely, that goes to Swansea.
Revealing mistake: The $100 bills in the briefcase looked quite fake and were obviously a prop. (00:13:40)
Continuity mistake: Parker is walking straight (legs/feet parallel) when he slips on the apple, but the still-frame photo that Adrian has on her laptop screen shows Parker's left foot at about a 45° angle. (00:04:40 - 00:10:20)
Revealing mistake: Driving home from meeting Gigi, there is an image on the windshield of a blue handicapped parking permit/placard that is supposed to be hung on the rearview mirror, but there is no placard hanging - the permit's image is superimposed on the windshield. The image even briefly appears and reappears. (00:34:05)
Continuity mistake: Marge had her left hand on a Win Fall ticket that (supposedly) was coming out of the printer on the side of the machine. Marge moved her hand away without removing the ticket. When the camera shifted, the ticket was not there. (00:54:10)
Continuity mistake: Simi enters the bedroom and the upper half of the bedspread is smooth. Aunt Claudia is holding a book with both hands, so she is not touching the bed. The front (somewhat aerial) view of the bed shows that the upper part of the bedspread has multiple ripples. (00:17:55 - 00:18:42)
Continuity mistake: Ishmael shots Karim in the right side of the stomach, but the wound moves to the left side.
Continuity mistake: During the "Good Afternoon" number, Ferrell and Reynolds are standing in front of horses. They're fairly close to the two. The scene changes and the horses are further away.
Revealing mistake: The guy with the sunglasses changes from behind and in front of shots. (00:09:46 - 00:10:15)
Continuity mistake: During their first encounter (the first we see in the movie, at least), Sheila sits next to Gary, and they both order Old Fashioned. Phil the Bartender makes a comment on that, and she shoos him off. Look at Kaley Cuoco 's bag; one of the straps keeps going on/off the top of the bag between shots. (00:03:30)
Factual error: The movie is set in the Northern Great Plains of the United States, and the tribe is identified as Comanche, but the Comanche were located in the Southern Great Plains, across present-day northwestern Texas, eastern New Mexico, southeastern Colorado, southwestern Kansas, and western Oklahoma.
Other mistake: When Marilyn is standing on the subway grate and the skirt is billowing up, there is one of the takes where there is a dark spot near the front of the skirt. All others are spotless.
Continuity mistake: After Art yells for Jesse to come to eat lunch, the stick of butter on the plate is roughly parallel to the edge of the table, but is diagonal when Art and Jess come to the table. A later view from the other end of the table shows the stick of butter parallel to the edge again. Some of the family members take a roll out of the basket, but none take any butter (so did not move it). (00:20:45)
Continuity mistake: The gingerbread man cookie falls into the coffee cup, and the top is barely below the rim. Looking into the cup, the top of the cookie is much further down but does not fall this fast. The coffee cup is about half-full. Jackson takes a drink. The cookie does not interfere with the flow of the coffee into Jackson's mouth. When Jackson lowers the cup from his mouth, there is no visible cookie. (00:08:20)
