Continuity mistake: When the girls are vandalising Jeff's house, when they're almost done, Josie and Isabel are in the van, almost kissing but then the bomb goes off. A second after the bomb, the van is empty and both girls are on the street.
Continuity mistake: When the first police officer looks at the body, Maggie's long hair is down her back, but is not when an officer takes a photo. (00:01:38 - 00:02:33)
Other mistake: In the Special Thanks section, Bobcat Goldthwait's name is misspelled as "Goldthwaite." (02:28:28)
Continuity mistake: The covered object (storage container or pet carrier?) is at an angle to and extends past Bob's desk, but is against the side of the desk when "Binky" the rabbit jumps onto it, as well as when Binky jumps from it onto the floor. (00:12:53 - 00:13:47)
Factual error: When Marcus is walking down the street after first meeting the team, he gets picked up by Johnny and his sister. You can see Government of Manitoba vehicles in the background, while the movie is set in Des Moines, Iowa. (00:22:38)
Other mistake: When Adam Sandler calls his daughter on a video chat in the car with her friend, the picture of his daughter is not the same as when she is in the car. When they jump between her and him on the call, her hair and background are completely different than they are in the car. (00:23:17)
Continuity mistake: Andy is walking alongside a highway and is roughly between the "End Road Work" and "Speed Limit 55" signs. There is a tall, thin sign pole on the right-front side of the screen. Andy is almost at the pole when there is a cut to Bishop breaking into and searching a house. The camera returns to Andy, who is still walking at the same pace and just reaches the pole, but he should be much further ahead. (00:30:24 - 00:32:10)
Continuity mistake: The desk lamp (which has an odd 2-3" "halo" around its perimeter) faces the screen (angled away from Sid). Suddenly, the lamp aims at Sid spinning in his chair. The lamp goes back to its original angle but varies a couple more times. (00:41:20)
Continuity mistake: Before Francois writes on the whiteboard (dry-erase), the words at the top are not boxed-in (or underlined). After being boxed-in, the words are surrounded by more of an oval shape, then not highlighted at all - but the words on the third line are boxed-in, followed by being underlined 4 times, to not underlined, to being boxed-in again. (00:17:28 - 00:19:05)
Visible crew/equipment: When Grace is entering the flower store, if you look closely at the door, you can see the reflection of the entire camera crew and equipment present. (00:16:07)
Factual error: It is Halloween night, 2023, but there is summer tree foliage (and even flowering shrubs some time later). There should be peak fall foliage in Vernon, British Columbia, Canada by mid-to-late October. (00:05:40 - 00:14:53)
Continuity mistake: The coat rack suddenly has a long-strapped tan purse/bag hanging alongside Juliet's coat. The purse soon disappears. (00:10:45 - 00:11:15)
Revealing mistake: More than once, when speaking to their robot doubles, it's obvious that both Charles and Elaine are actually just talking to nobody, given their mannerisms.
Factual error: Fodor is woken by the nighttime cry of a fox, whilst staying on the Isle of Man. There are no foxes on the Isle of Man, and none were present in the time period of the film. (00:37:45)
Visible crew/equipment: Emma Stone is let out of the carriage and runs to the left of screen across the leaves. The camera follows her. On the bottom of the frame, right side, the shadow of the camera is visible. This is the scene before the assistant shows her the frog.
Continuity mistake: Near the start the left side of Romy's hair dangles, but strands are suddenly held behind her ear. (00:06:45)
