Continuity mistake: In the first confrontation with Tedjo, he kicks away Vic's glasses (obviously from the wrong distance, as there's no way that kick would connect) and they fight some more. When Vic misses with his punch, Tedjo kicks him in the chest, doing it with the left foot, that becomes the right foot in the following shot. (00:02:00)
Continuity mistake: After spearing Tedjo through the wall, Bautista throws a piece of equipment at him sending him flying back on his butt. Tedjo slides right past some artwork on the floor, but he is shown stunned at its side and partially on top of it in the following shot. (00:03:15)
Continuity mistake: In his escape from the cops at the beginning of the movie, we see Iko Uwais drop down 2 floors from the 8th, where Bautista and Gillan are. One more in the overhead POV. Another one in a separate shot. Another shot again, another floor down. Then he drops another floor. Then Batista hits him with the tray making him fall 2 floors, but we see with that shot the difference between the two, and it's of 5 floors. It does not add up. (00:03:35 - 00:04:20)
Other mistake: Vic is helpless as Morris is bleeding to death on the sidewalk. She has her feet on a manhole in the view before the Staples, but in the overhead shot it's him with the feet on in it. On a sidenote, when he is helping her out and the passersby are seen, on the left you can spot by the Italian place under the umbrella a few extras who are having a great time and laughing, not bad for being 20 feet from a shootout and with a dying cop in front of them. (00:05:30)
Continuity mistake: Stu picks up a guy after he's first introduced, and tells him to stop calling him "Stuber." In the first shot, Stu is looking in the other guy's direction, but when the camera cuts to a different angle suddenly Stu is looking straight ahead. (00:06:43)
Continuity mistake: Vic's colleague brings him the plate with the tiniest piece of cake, the red fork switches side between shots (it also gets upright in the next shot 'stabbing' the cake instead of lying on the plate, but that could have been done by her out of frame, even if it's not a gesture that makes a lot of sense). (00:08:55)
Continuity mistake: Throughout the scene when Angie tells Vic about the Feds taking over the case, Vic's paperwork (the mugshot, the photo) change spot a few times. When Angie stands from the desk, Tedjo's mugshot is on Vic's cake's platter, even, but it's nice and clean back on the folder right after. (00:10:00)
Continuity mistake: Stu receives the flyer about the gym from Becca; he grabs it with his right hand, which becomes the left in the close-up. (00:10:20)
Other mistake: When Victor undergoes the eye surgery procedure, the doctors have opened his file, and it's in a June 2018 folder. The movie is set in August 2019, it's a bit unlikely that a whole year went past between the doctor visit and the actual LASIK. (00:12:05)
Continuity mistake: Vic is chatting with her daughter at the Chinese restaurant. He tells her to stop breathing (the way she does it, at least). Cut to a brief reverse shot when she is eating from the chopsticks; she is replying to him immediately, mouth completely free. In that spot of the convo you can pick up more inconsistencies, like the hair on/off her shoulders, and next Batista's chopsticks held up that disappear during the following cut. (00:13:25)
Continuity mistake: Stu pulls over by the new customer (Vic); he bangs on the hood, then there's a reaction shot of Kumail Nanjiani, and then again a shot from inside the car. The wheel is turned differently between shots. (00:16:20)
Continuity mistake: Stu just picked up Vic and he needs to do a U turn; first time we see the street there's just a parked car and no incoming vehicles from the worksite, but all of a sudden one appears for the rest of the scene, honking at Stu as he struggles with the maneuver. (00:17:10)
Continuity mistake: Driving to Koreatown, Stu is trying to strike up conversation with Bautista. In some shots he has the sun on his shoulder, in others he does not. And it always changes between shots, never during a single time when the camera holds the same view. (00:18:00)
Continuity mistake: An enraged Vic opens the car window and tosses the glasses out. It is clear that for these two strictly consecutive actions, the car is in a completely different spot (scenery, cars behind). (00:18:05)
Continuity mistake: Vic shows the badges at the two students that are Uber pool-ing with him. He is turned in a different way in the reverse shot, which makes the position of the badge inconsistent as well. (00:19:25)
Continuity mistake: Stu looks at his phone finding the 1 star review mentioning "Andre the Giant"; he's holding it in a different manner between the close-up and wider shot. (00:20:55)
Continuity mistake: Talking with the stripper backstage, Stu reminisces about the time when "her Harry met my Sally." The two dancers in the background (sailor and mime with suspenders) are suddenly turned around when reflected in the mirror. (00:28:00)
Continuity mistake: Driving to the suburb where the former cellmate is, Vic shows the pen knife to Stu. The pen is turned the opposite way in the close-up. (00:32:35)
Other mistake: The strip club the protagonists visit is, according to what Bautista says, in Compton. They are outside the joint a couple minutes before 3 PM. From there they need to go to Amo Cortez's place. When they arrive in front of the house, Batista grabs the keys and you can take a peek at the phone in charge; the address is highlighted and it is 111 Drysdale Ln, which would be in Orange County and 20-30 minutes away from their starting point, but the phone goes 'ping!' the moment the door closes, and shows it's 4:05 PM. Considering Madame Titties only mentioned a gang and not an address, and Batista earlier ordered to head to Long Beach (pretty weird place to go for a gang called Alamitos 13, obviously they'd be based in Los Alamitos), one could think that there's a part of the investigation not shown...but the phone showed a long uninterrupted course instead, with an estimation of 45 minutes of drive. (00:33:05)
Other mistake: Vic receives the bill from Uber; it says "Your Friday afternoon ride with Stu", but the ride took place on a Wednesday (as seen on Stu's phone in front of the dealers' crib: Wednesday 28 August 2019). (00:33:50 - 01:24:50)
