Near the beginning of the film, when Sam is reviewing Zoe's file on the plane, Zoe's birthday is shown as 03-08-99. Later, Zoe's birthday is shown to be 03-08-02 (the code to the computer), a difference of 3 years.
Near the beginning of the film, as Sam is driven to Zoe's residence, she is informed that Zoe's mother passed away when Zoe was 10. In a later scene near the end, she and Zoe discuss how Zoe's mother passed away when Zoe was 8.
When Sam is reading Zoe's dossier, Zoe's birthday is written as 03.08.99. When Zoe enter's her birthday as a security password she enters it at 030802.
At 42 minutes when Sam is putting her hair up, it changes from being almost completely up, to down, and back.
When the three women are rescued, near the end of the film, an ambulance is seen displaying the "Star of life" symbol, used in Western countries. Morocco, like all muslim countries, uses the Red Crescent as the official ambulance marking.
During the taxi ride that takes Sam and Zoe to Hassine building, a brief shot shows the taxi driving on the left. In Morocco it is right-hand traffic.
For the "principal costume standby" credit in the end credits, the word "principal" is misspelled as "principle".
During the invasion of the house, one of the invader's ARs are shown with no rear sight or optical sight, only the front sight base.
This would not be a likely scenario in any reasonable situation.
At 33 minutes after Alik shoots one of the invaders, his slide locks back (indicating an empty magazine, no rounds left, aka he only had 2 blanks) yet he continues down the hall, and in the next shot the slide is forward again (indicating, once more, a loaded weapon)
In the end when Sam is shot in the arm she walks out of the house bleeding with a serious wound. But the ambulance crew is more concerned about Rima and her minor wounds and taking no notice of Sam.
in the beginning when they are driving away in the attackers car, the arm of a person standing in the back can be seen for a second.
On the main movie poster, Noomi Rapace is holding an airsoft gun "WET5268" instead of a real Glock 17 or at least a good mock-up.
