Continuity mistake: When The Rock is putting early in the movie he is on the phone, when the shot comes back to the room the putting green is missing. (00:01:50)
Factual error: In this relatively low-budget but extremely well-produced 2013 science fiction film, a 6-man crew travels from Earth to Europa (one of the moons of Jupiter) to search for traces of life in the vast oceans beneath Europa's icy surface. One of the astronauts dies in-transit, leaving 5 crewmembers to complete the mission. When the large "Europa One" interplanetary spacecraft arrives at its destination, all 5 surviving crewmembers descend in a small landing craft to the moon's surface, leaving the Europa One spacecraft in orbit, totally unmanned. This is an inconceivable factual blunder. The narration plainly states that this mission picked up where manned lunar missions of the 1970s left off; so, many of the same protocols are in place. Just so, no manned space mission would ever abandon the primary space vehicle in orbit, placing the mission at risk by sending the entire crew down together in a landing party. At least two astronauts should have remained aboard the orbiting Europa One just in case the landing mission went sideways (as it does in this film).
Factual error: This film takes place in the north eastern USA. During the beautiful scene with the large black bird soaring above, they added a close up of an Andean Condor. The Andean Condor only lives in South America; Peru, Argentina, Chile, etc.
Continuity mistake: The needle Cheryl's holding goes back and forth from her right to her left hand between shots.
Character mistake: In the scene where Beatrice looks at the newspaper clipping about her accident. The word "sentence" is misspelled "sentance" (00:24:35)
Visible crew/equipment: When Julian follows Chang around the streets, during the second point-of-view shot from Julian's perspective, you can see the distinct shadow of a cameraman with a camera on his shoulder cast on the wall. (00:38:02)
Continuity mistake: Max is wearing a suit jacket while he is beating a young woman. He throws her against a dresser and then when he goes to pick her up he is in shirtsleeves.
Continuity mistake: At the beginning, the little girl's body changes position. When the trucker finds her, her lips are slightly apart, but when the police examine her body, her lips are closed.
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)
Visible crew/equipment: When Sonya is getting ready to get in the shower there is a shot from inside the bathroom of her in her bedroom, if you watch the closet closest to the bathroom door you can see the shadow of a nearby crew member cast on it, moving around. (01:04:27)
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.
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: 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.
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: 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: 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: After the fake movie intro, the two guys drive to a secluded place where their drop is supposed to happen. "Cheno", the one in the driver seat, has the right hand down his side and the left hand on the right side of the steering wheel in a pretty unique position. But in the reverse shot, it's his right hand on the wheel. (00:03:00)
Continuity mistake: When Ivan invites Richie onto his yacht for the first time, a jet ski pulls into Ivan's close-up, and disappears after it cuts back.
Factual error: It was very nice of the East Anglian Transport Museum at Chappel and Wakes Colne to provide a train for the coder to go home in, and come in to work. The station is even in Suffolk; but of the two lines through the station, one is used by public trains, and the other by historic preserved trains. When the coder gets off her morning train, it is seen passing across points from the museum platform line into the railway museum, rather than continuing up the line to Sudbury, as a public train would. Appropriately, the train is a heritage DMU - a museum exhibit which has not been used on the main line for at least 25 years. So that's three reasons why she's not on a train which actually goes anywhere.
Continuity mistake: When Paul Walker bends down to see his wife's body, the clock reads 09:47, however in the next scene, the time stamp on the movie shows 09:30am. (00:13:00 - 00:13:40)
