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: 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.
Continuity mistake: As the two assistant workers walk away from the prison building at the end of the first day, Charlotte Gainsbourg's grip on her folders switches between shots.
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.
Continuity mistake: The protagonist just unveiled to his boss the "nest" ad, to which he suggests some not-so-minor changes. Luca Argentero is holding the drape in two very different ways between shots (first with bunched cloth sticking up top, then simply folded). (00:05:00)
Continuity mistake: Before Jesse's plate is placed on the table, the salt and pepper shakers are about a width apart. They are almost touching for a while, then back to being spaced apart. (00:10:20 - 00:11:00)
Continuity mistake: The glass that was dropped and shattered on the floor had a different pattern of fragments when Mitch [Robin Williams] knelt to clean it up. Most obvious was that the majority of shattered pieces settled toward Mitch's feet but were on the opposite side of the largest piece of glass during clean-up. There's also a "stupidity" in the way Mitch wiped up the glass - pressing down on the thin towel (apparently to entrap fragments), which is most likely to result in getting pierced. (00:01:40)
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.
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: 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)
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: While father and son are eating beignets, the passers-by behind them are not continuous between shots.
Revealing mistake: In the news reel detailing the Kohinoor theft, a few headlines appear, and at least one persists on screen long enough to easily spot the inconsistency between headline and article (filler text presenting a new local magazine from the London district of Lambeth). (00:09:00)
Factual error: While Evans and Eve are still in Grand Central they overhear an announcement which states "According to Port Authority policy This station will be closing for the evening." Grand Central is not part of the NY/NJ Port Authority. Also Grand Central is a terminal, not a station, as trains do not pass through Grand Central, they enter and turn around.
