Continuity mistake: Judge Pendergast calls the daughter of his therapist, who reacts with typical New York aplomb. During the scene, the same extras continue to walk back and forth with no logic, sometimes coming twice from the same direction, even. Most egregious example the blonde with a ponytail and sunglasses on top of her head. She is behind Jennifer Aniston in the opening shot and appears at least 4 times (possibly more but there's another blonde too -unless it's the same one who occasionally removed the glasses) and walks away from Aniston and Forte two times in a row. (00:17:40)
Continuity mistake: Stretch takes the licence plate off the limo just before it's stolen. When he's clinging onto the bumper as it's being towed, the plate is back on.
Factual error: When the guy is talking to him on the phone and the Russian smashes it on the floor, the phone smashes and the battery comes out but the guy other end can still hear him. (01:04:00)
Continuity mistake: During the early part of the movie, the left rear door of Doc's car is dented. For the rest of the movie, the dent is gone.
Continuity mistake: There is a scene where she accidentally stabs someone - she gets blood all over her from the stabbing and then in the very next scene is wearing the same shirt without blood stains.
Revealing mistake: About seven minutes in, during the scene where we see Cooper helping the Nerd as a cameraman, you can tell that Cooper has been added to the scene using green-screen effects, as the actor was unavailable to shoot at the location. The lighting on Cooper doesn't quite match the lighting of the scene, and you can see a slight "blur/feathering effect" around him where the greenscreen background was removed.
Plot hole: When Mr. Shepherd arrives at the school he learn Joseph's (the student's) name but loses his memory. When they are telling him the nativity story Shepherd says "this Joseph" when referring to the student, but he shouldn't remember it.
Continuity mistake: Vincent and Oliver are eating ice cream, Vincent's ice cream cone repeatedly changes levels of ice cream left in his ice cream cone as he eats it. (00:48:00)
Continuity mistake: When Hugh Grant writes "Protagonist" on the board, the writing changes depending on the shot, most noticeably the G - sometimes it looks a bit like a backwards question mark, other times it's so slanted it looks more like an S.
Revealing mistake: During the opening, one of the shots showing infographics about the stolen diamond lingers long enough to allow the viewer to spot the most obvious kind of filler text - literally the "Lorem Ipsum."
Continuity mistake: When the young girl is on the beach removing her socks, she takes three socks off.
Suggested correction: Jess is wearing yellow socks with polka dots, and yellow wellies. There are three shots in which we see Jess removing or tossing her two yellow polka dot socks, and one of her yellow wellies.
Revealing mistake: As Glenn, Blake and Monica are being surrounded by zombies, as Monica asks "Fucking hell, how many more of these are there?", in the background you can see a zombie sitting astride his victim, flailing away with a hammer or hatchet. It is obvious that he is just swinging his arm back and forth, without connecting with anything. It looks as if he is dusting, not slaying someone. (01:23:50)
Continuity mistake: In a scene at a night club, Colin Firth's friend has a glass of red wine in his hand and then he has a glass of white wine.
Continuity mistake: When Dex sees "his" son for the first time, the kid in close-ups is playing with the toy that dangles from above, and there's a toy football by him. In the wider angles none of the above is happening. (00:38:40)
Continuity mistake: At the first gig of the band "Soronprbfs," Frank enters the stage. As he attaches his microphone, Nana, the drummer, is standing with her back to the audience. Clara starts her keyboard playing, cut, and Nana is sitting and waiting for her cue. (00:08:00)
Continuity mistake: While father and son are eating beignets, the passers-by behind them are not continuous between shots.
