Continuity mistake: Her bruise from being shot in the vest appears and disappears and reappears, also moves from her left to her right side.
Factual error: J-Lo plays a Chicago cop, but in the very first scene you can see the CN Tower in the background, obviously shot in Toronto. The tower is seen again in the background later in the movie.
Continuity mistake: At the end, after J-Lo leaves the wedding, her man is waiting outside for her. Her jeep is parallel parked between two other cars, but when her man decides he is going to drive for them, he gets in and pulls straight out. He doesn't even turn the wheel to get out of their parallel parking spot.
Factual error: While walking downtown in "Chicago", you can clearly see the blinking sign of Honest Ed's which is a Toronto department store and is found nowhere else.
Continuity mistake: In the bar scene where J-Lo goes over to meet with Catch at his table, they are both served a bottle of beer. Each time the camera shoots Catch at the table, his beer bottle is turned in a new direction. First the label is facing front, then the bottle is turned to the left and the right. This happens throughout the scene but yet you never see Catch pick up his beer bottle once.
Continuity mistake: After the scene when J-Lo hit her brother, she is sitting at home, putting ice on her fingers. Then Catch knocks on the door, she answers it and he closes the door, but right in the next shot, the door is wide open, you can even see the flat number, 85. (00:51:30 - 01:51:35)
Continuity mistake: When J-Lo and Catch are in the park, Catch runs to the top of a cliff and jumps into the water as J-Lo watches him jump and hit the water. In the second it takes Catch to bring his head above water, J-Lo has vanished and is already to the top of the same cliff ready to jump. There is no way she could have gotten undressed and to the top of the cliff that fast.
Continuity mistake: At the end of the film, Catch is driving away. You can see the reflection in the windshield of the foliage above the car moving but if you look through the back of the car, it seems the car isn't moving at all.
Continuity mistake: When Jim Caviezel goes to the flat, after she did not show up in the coffee shop, J-Lo follows him and she closes the door. When they are in the apartment talking, the door behind Jim Caviezel is now opened, then it's closed, then opened again. (00:38:00)
Factual error: In the beginning of the movie, there is a scene (which of course was shot in downtown TO) in which a bus passes in the background. It is obvious that it is a TTC (Toronto Transit Commission) bus.
Factual error: When J-Lo and her man go to the Blues club, and her guy starts playing the trumpet, it is obvious that he isn't really playing because his fingers don't move with the notes. A trumpet's range is wide, but not the way he was "playing".
Continuity mistake: At the beginning of the movie, when Jennifer Lopez is chasing one of the guys from the drive-by shooting under a highway/bridge, the shot goes back and forth between her running, pumping her arms up and down, and holding her arms straight in front of her pointing a gun.
Continuity mistake: After jumping in the water from the cliff she surfaces too quickly. Having jumped from the same spot into the same water, I know how deep you go and how long it takes to surface.
