In 1992, when Saldeya arrives in the United States, she is seen wearing a t-shirt with a big "Japan Rags" logo on it. Japan Rags is a brand owned by French clothing company Le Temps des Cerises, which was founded in 1998.
Cataleya knocks over her shoes on the policeman's desk when she is assisted up in her drunken state. The policeman then adjusts the shoes on the edge of his desk, but after the camera cuts to Cataleya being led out, he adjusts them again.
At the end of the film, before the credits roll, two people can be seen sitting on the bench in the background. However, after Cataleya hangs up the phone, a close up of the bench is shown, with only one person sitting on it. As the bus is departing, the two people are there again.
Cataleya states that her parents were killed in front of her when she was nine years old, yet the end credits list her as being ten in the flashback. Also, in the edited version released for cinemas, her parents were killed outside the apartment where Cataleya sits. So she only hears the gunshots, but never actually sees her parents die, or even their dead bodies. (Although in the full version of the film, she sees both her parents die, one after the other.)
In the scene where she is swimming in the shark tank, she lifts the massively heavy piece of glass to exit the water. If you look at the corner of the glass slab, you can see the large eye-hook screwed into the glass and the cable attached to it to help her lift the glass.
When Cataleya enters the US through Miami as a child she escapes from her federal guardian through a window out the bathroom in the airport. There isn't an international airport in the US with bathrooms that have windows connecting to the outside.
When they are searching the garage for Cataleya, Agent Ross says to "check every boot". This is a British term for what Americans would call the trunk of a car. The actor is British, but his character is supposed to be Amercian (based on his accent) and so wouldn't use this term.
In highlighting the arrival of the antagonists into Chicago, a Boeing 747 operated by KLM was captured landing at O'Hare Airport. The errors lie in the facts that KLM operates into O'Hare only out of their hub in Amsterdam, and even if they did operate into New Orleans (the baddies' place of residence) law prohibits a foreign carrier from operating in a domestic capacity within the US. So it is impossible for them to have taken that type of aircraft operated by that carrier between New Orleans and Chicago.
The GSM location algorithms only returns the X-Y coordinate, the location of the cell phone in some error distance. But FBI detected her flat, Z coordinate, the floor of the flat without any mistake and this is even impossible with current technology.
When Cataleya attacks the Don's house she fires an RPG that enters the living room and explodes, destroying almost every item of furniture in the surrounding rooms, even the table that Marco and his hences were standing around. But in the next scene everyone is still alive, even though the table is blown to bits.
The goof items below may give away important plot points.
When Cataleya discovers her murdered grandmother and uncle, she is wearing brand new boots with clean soles. Her boots should have been dirty under the bottom as she had been running through underground tunnels to escape the FBI invasion of her home.
