Continuity mistake: The protagonist at the beginning of the movie sunbathes topless.The camera is positioned where the kid is spying her, and in that wide shot she is placing the garment she removed close to her lower half of the body. When he waves his hand casting a shadow over her eyes, the bikini top is in the corner of the towel next to her head. (00:01:20)
Other mistake: Cops do not show up at a desert murder scene "in the middle of Bum Ass nowhere, Australia" on a blazing hot day eating a freshly opened and still hard ice cream bar.
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.
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 Keisha shows the father the painting she made, the father places it on the table over the color palette. Then after Keisha screams in the father's face, the magazine is gone. He sprays her with breath spray and replaces the painting over the color palette. (01:07:00)
Other mistake: Throughout the film, you can frequently see many people's faces blurred, phone numbers blurred, store-fronts blurred, etc. This is because the production could not afford the rights to show these people, places and things, and simply blurred them out.
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: 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: The movie opens with a man walking with a dog by a body of water. He is holding the leash with his left hand and the dog is by his left side. Cut to the next shot taken from across the water, the leash is now in his right hand and the dog is on his right. (00:00:20)
Continuity mistake: The Boss kneels by Tasha after hitting her, and asks her did she get the money. In that particular shot, blood trickles down her face in a single clean path, but in the close-up and in other later views part of the blood branches down coasting her nose. (00:39:10)
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)
Character mistake: Luca calls Eve in the dark outside the house, searching her. But they all know that Eve is deaf. (00:33:20)
Factual error: Near the end, Zoe and Trey battle to the death, Zoe armed with a tomahawk and a knife, Trey armed with a Husqvarna chainsaw. During the battle, Zoe manages to amputate Trey's right hand, with which he was gripping the chainsaw's safety release and trigger (as his left hand gripped the support handle). Bellowing in pain, Trey continues swinging the chainsaw by its support handle with his left hand. Lo and behold, the chainsaw is somehow, miraculously, still revving in-and-out, which is only possible if the safety release is continuously depressed with the palm of the right hand as the fingers rhythmically flex to squeeze the trigger. Of course, with all major tendons in the wrist severed, an amputated hand cannot grip or flex or squeeze anything.
Continuity mistake: The protagonist is told about the budget cuts that will lead to the library shutting down. During the scene, the strap of his hat keeps going back and forth in front / behind his ear. (00:02:05)
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)
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: When Diana's father's surgeon shows Diana around the hospital, they end up in an operating room and they are both wearing street clothes. Problem is there are doors in every hospital where operations are performed and no-one is allowed past those doors without wearing scrubs, paper hats, booties and face masks, no matter who you are - they have to keep the operating rooms as clean as possible.
