Continuity mistake: Jen unboxes the stuff she grabbed from the basement where she spotted the railroad tracks. She picks up a large vase which she shows to her business partner; the hand at the bottom is the vase is the left or the right one depending on the camera angle. (00:10:40)
Other mistake: In final 14 minutes, the greys are attacking the house. Several screws are "unscrewed" from the plywood. The first two are turned the wrong way, and the sound effect is of tightening. (01:23:54)
Factual error: On the Miz's certificate of appreciation hanging on his refrigerator, the words "Department of Defence" are visible. "Defence" is the British spelling of the word defense, and any official U.S. military document with that word would have used the U.S. spelling. (00:14:30)
Character mistake: In the scene discussing the provenance of the mirror, the girl stated that Sherman marched to the sea in 1865. It was actually 1864.
Continuity mistake: When Aaron throws the umbrella down it turns inside out as it lands on the floor. A couple of shots later the umbrella can be seen from above and it has turned right side out.
Plot hole: Luka sneaks into Bayonetta's hotel room and plants a hidden microphone. While sneaking out, he is caught. That's when he is astonished to find a child with Bayonetta who calls her "mummy." He does eventually escape the room and sits in corner with his radio, surprised that they both went to bed and he receives nothing. The problem is: One must be an idiot to plant a mic in a lone woman's hotel room in the dead of the night, unless he truly enjoys listening to her snoring! Planting the mic in her apartment or office, or on her mobile phone makes a lot more sense.
Character mistake: In the scene where Beatrice looks at the newspaper clipping about her accident. The word "sentence" is misspelled "sentance" (00:24:35)
Factual error: The black Range Rover used throughout the movie has the wrong licence plate. The third and fourth numbers on the plate (UK spec licence plate) are '0' and '9' which refers to the vehicle as being a 2009 spec. The Range Rover used in the movie was discontinued in 2006 and was replaced with the face lifted model which the one in the movie is not.
Revealing mistake: Before Derek punches the side of the wall, you can see the weakened area of the wall before impact. Look at the color difference.
Continuity mistake: At the end the guy is watching the video of the man that shoots himself in the chin, blood and bone go everywhere, then it shows the guy and girl walk in but there's absolutely no blood. They would have definitely noticed it.
Continuity mistake: When Swifty is calming the horse, and the scrap dealer exclaims, "He's fast!", Swifty has his face pressed against the horse's nose; in the cut to the long shot, Swifty is suddenly facing the horse, looking up at it. (00:25:00)
Continuity mistake: By the end of the film, we realise that the Djinn (in this case an invisible and shape-shifting earthly entity of Islamic lore) has staged most of the film's events as a mass illusion. Meaning, the Djinn is a deceiver and can lead humans into dangerous and even deadly situations, but the Djinn cannot perform physical miracles (or else the whole movie would end almost as soon as it started). At the story's climax, the lead characters, Khalid and Salama, end up in the 62nd-floor penthouse of a luxury high-rise, where Khalid drops Salama to her death from the penthouse balcony, just as the vengeful Djinn intended. However, only minutes earlier, we see that the high-rise building is actually still under construction, and it's stated that the building is months away from completion (its main entrance and plate glass have not even been installed). The Djinn only created the illusion that the building was completed to deceive the lead characters. In reality, without electricity and functioning elevators and hundreds of feet of completed stairwells, there was no physical way for Khalid and Salama to reach the 62nd-floor penthouse suite of the high-rise for the climax scene, even if they were being deceived by illusion.
Continuity mistake: When they are discussing whose pinkie gets cut off, Vince grabs Craig by the neck and pushes him against the refrigerator. Craig is first shown pushed against the right hand side of the refrigerator, but whenever the camera is on him for the rest of the scene, he is shown standing against the left hand side of the refrigerator.
Factual error: Just after Spud gets suspended from school, his mum is looking through a property catalogue of London homes. All the telephone numbers shown start with 020 7. The film is set in 1991, and inner London telephone numbers at that time started with 071, not changing to 020 7 until June 1999.
Continuity mistake: After Seligman offers to wash Joe's coat, she tells him not to and it's her coat. He shrugs it off and sets the coat on the bed and turns, walking away. It suddenly jump cuts to him being back at the foot of the bed facing her and asking her what happened.
Continuity mistake: The layout of the two slices of pizza on the tray and the position of Tyler's fork on his plate differ after Matt reaches the table. The slices of pizza are touching, then spread apart like a "V." Tyler's fork moves from being diagonally across his plate with tines facing him to being situated near the edge of the plate with tines facing Jessica. (00:13:19)
Continuity mistake: At the beginning of the movie, the waiter is wheeling the cart out of the building. Two workers are loading the van, with Saman to order them around. One is wearing a hat, the other isn't. Hatless Guy walks out of the van first and is sprinting back towards the building, with Hat Guy noticeably behind, but in the next shot Fabrizio passes the cart to Hatless Guy and Hat Guy is already way past them both. (00:01:30)
Continuity mistake: Emily Smith-Dungy just kicked her bags in the snow. Her neighbour and schoolmate Kat drives by and offers her a ride home. Emily after initially rejecting her help accepts it; the trophy switches hands from the first quick shot to the next. Her scarf is also positioned differently. (00:08:40)
Continuity mistake: When the awful cousin Charlotte hands Gwen the slice of unbirthday cake, she does it with her right hand, left hand, right hand. (00:04:20)
Continuity mistake: After stabbing the bad guy at the beginning, Callahan for some reason pulls back and somehow dives past a door managing to drag in a grown woman who was all crouched down by the entrance. Wonky physics of it aside, the bad guy shoot at him, but shoots just a hole in the door frame. The hole appears to be CGI, and in fact when Callahan shoots back from the bedroom, the hole is gone. (00:01:35)
