Continuity mistake: As the "lone wolf" escapes on the bike, there's a fancy swooping camera shot which tracks him, cutting to a shot from the front just as he scythes between two dark cars and past a police car. In that quick shot a woman suddenly appears cowering by the police car who wasn't there before.
Continuity mistake: Before taking Michael's mask, Corey calls Allyson and tells her to meet him at the diner at 9:00 pm. Later we see Allyson at the diner waiting for Corey, but when she checks her phone and sees Laurie is calling the time is 5:36 pm. (01:13:56 - 01:24:41)
Continuity mistake: When Sarah fires at the jeep chasing them she brings the weapon back in with the slide in the normal position, in the next shot it is in the locked back empty position. (01:26:50)
Continuity mistake: In a pivotal scene in the middle of the film, Josh and his stepmother Constance are having a conversation about how Lyle has helped Josh adapt to life in New York City. In the background, the same woman can be seen walking past them multiple times. She is wearing an open gray sweater with an orange shirt.
Continuity mistake: Marion's shoes change when in the museum, from heels to flats.
Continuity mistake: When the FBI realises that the Ford Bronco that Alex Lewis shot an El Paso PD officer from was full of pigeon droppings, and Det Marquez remarks that Lewis' burned-down family bakery was full of pigeons, it can be seen through the office windows that it's still daytime outside. However, when the FBI arrive at the bakery, it's late at night. It is unlikely that the FBI would take hours to show up at the bakery given how time-sensitive it was to find Lewis, or collect evidence on his whereabouts.
Continuity mistake: When Priscilla meets Elvis in Germany the position of the letters on the bed and of the papers scattered on the floor change positions between shots.
Continuity mistake: When the moderator tells Lydia "I couldn't help but notice you flinch just a little bit", Lydia has her right hand placed firmly on an armrest. When the shot cuts, her right hand is away from the arm rest. (00:09:15)
Continuity mistake: RJ got into his van and drove parallel to the house, almost reaching the end (right side) of the house when he saw Pearl in front of him and stopped. When RJ got out of his van, it was parked near the beginning (left side) of the house that he had already driven past. Also, Pearl was standing in front of a fence, so it didn't make sense that RJ would be driving straight toward a dead-end. (00:57:07)
Continuity mistake: The instructions Evelyn is given had two copies created for the film - the handwriting and circling of the numbers change between shots when she's reading them in the IRS office. Notably the first time we see the instructions it says "don't forget to breath" at the bottom, then later that's changed to "breathe" as it should be. Although interestingly that change is the only one on that version of the notes, implying someone caught the grammatical error during filming and added the "E."
Continuity mistake: The orange feather toy that was in the cat bed with the cat when Sam got to the bookstore was not there a couple camera shifts later. (00:25:33 - 00:26:25)
Continuity mistake: The first time Tess tries to open the lockbox with the key inside when she gets to the house, the way she is touching/holding it changes between cuts. Specifically, she goes from only having one hand on it to both hands.
Continuity mistake: Jimmy's Suburban had a stick-on blind spot mirror on the driver's side (also shown on CCTV when he left the grocery store near the beginning of the movie), but the blind spot mirror was not there when he was driving away to get Natasha on a boat. (01:22:55 - 01:25:58)
Continuity mistake: The kitchen walls were distorted (at awkward angles), but Zero got to the house around 6:46 and talked to Shelly for a short period of time. The now-blurred clock on the wall appeared to advance to almost 6:47, keeping a reasonably approximate pace with the scene's progress. However, only about 30 seconds passed until Brandon came in, but the clock (no longer blurred) had jumped to 6:50. (00:28:00 - 00:28:50)
Continuity mistake: Riley puts the red hard-covered book and two others into the box, but puts the same books into the box when Gabby starts to help. (00:13:35)
Continuity mistake: Before the family went outside, the fire extinguisher was part-way below the window sill. When Peter (father) went inside, the fire extinguisher was away from the window sill (more toward the right of the screen). (00:07:33 - 00:09:12)
Continuity mistake: Kol shouts, "Stop the car!" Adam slams on the brakes from a cruising speed, yet miraculously, the car is bumper-to-bumper with a parked red SUV. When Kol gets back into Adam's car, the red SUV should be visible. However, outside of the windshield, there is a white blur. A car drives close by on a perpendicular road that wasn't there before Adam stopped. (00:15:48 - 00:16:20)
Continuity mistake: After Ross is shot, he lies on the pavement with his head to the left of the white line, but later his head is to the right of the white line. (His body would not be rotated 180° by police.) His head is on the white line in between this discrepancy. (00:06:38 - 00:09:30)
Continuity mistake: Jenna takes one red cup from the 3 stacked next to the higher stack and returns the two cups to her left (and left of the higher stack). Jenna uses her left hand, supported by her right, to handle the bottle of wine, but the 2 cups disappear after she sets the bottle on the table. (00:19:50 - 00:20:14)
Continuity mistake: Diana is meeting a client who is really into fisting, and does not take nicely her refusal to be on the receiving end of his knuckles. As he shoves her to the floor, her hands are plainly on sight, and they hold nothing, but conveniently when she is on the floor in the next shot she is holding the mace spray can. (00:14:15)
