Continuity mistake: After Creasy cuts off the first finger of the first man he kills, he is using the car cigarette lighter to stop the bleeding. When the shot changes to show him using the lighter, the man's finger is seen bent around the top of the steering wheel.
Continuity mistake: When Creasy is in the car with Jorge Gonzales, Gonzales' can be seen with his sunglasses on when they were not on immediately prior.
Continuity mistake: When Creasy is cutting off the fingers of Jorge Gonzales, the sunglasses resting on Gonzales's nose constantly changes from one shot to the next. In some they're halfway down his nose so you can see his eyes, in others they're pushed all the way up. (01:18:00 - 01:21:00)
Revealing mistake: In the rave club, right before Creasy fires the sawed-off shotgun at the woman who's trying to hide, the part of the wall that will be blown out is visible (it's a patched-up circle). (01:28:30)
Continuity mistake: When Creasy's friend Ray is sitting on the couch at the Agency for Federal Investigation and calls Creasy an artist of death, from a side shot he eats a piece of food, licks his fingers clean, and from the shot it is clear that he is holding nothing in his hand. However, on the next shot from the front, Ray is holding something in the same hand, points to it with the other hand, leans forward and throws it on a plate, then picks up a napkin and wipes off the fingers he had just licked clean in the shot before.
Continuity mistake: Within the first hour of the film in the scene where Creasy is driving Pita and her mom to school, the mom is seen sitting behind Creasy in some shots and sometimes there is no one behind Creasy when it changes camera angles. Then towards the end of the scene the mom appears behind Creasy once again.
Continuity mistake: As Creasy is crossing the street, searching for a site to use the RPG, he is followed by a couple, a blonde in a striped top, and a man in a leather jacket. The couple passes in front of Creasy in one close-up, passes behind him in a second, long shot, then passes in front of him again in the next close-up.
Factual error: After Samuel shoots himself he is lying on the floor next to the Glock he used. The slide is locked back even though he had only one round and no empty magazine in the gun. The slide will not lock back in this configuration.
Visible crew/equipment: When Denzel is trying to get information on Samuel Ramos he is talking to a woman on the phone. When we first see her talking next to her computer, this shot begins looking over a rail and pulls back. As the camera pulls back, the track that it is sitting on is visible on the bottom right of the screen. You can also see electrical wire next to the track.
Continuity mistake: When Pita asks her father to drop her piano lessons, her father hugs her. His hand, between shots, continually moves from resting on her head to on her shoulder.
Other mistake: When Creasy is coaching Pita in the home swimming pool he calls her by his name, Creasy, not Pita.
Other mistake: When Sam is going through Creasy's resume in the back of the Mercedes, the resume speaks of a "Mr. Rosche", not Creasy. (00:09:40)
Continuity mistake: When Creasy kills the first Judicial Policeman, the scene where he cuts the guys fingers off and then shoots him in the head, he pushes the car down a hill. The first angle is from Creasy's view, and the hill is all dirt. It then cuts to a second angle from the air, the hill is now all grass. When the car hits the school playground, it looks like it fell from the sky, with no hill around. (01:22:15)
Continuity mistake: When Creasy is searching Pita's room for her journal, her mother walks in and suddenly starts talking with a southern accent.
Continuity mistake: When Creasy is trying to get the number plate of the car following him, Pita is trying to write the number down as well. It can be seen that the last number (9) has been rubbed out. Creasy later finds the diary with the correct number in place.
Suggested correction: He asked the journalist to search the number for him and then he added it for Pita.
Factual error: In the scene where they are first being chased (and where Pita writes down the license plate number), the plate on the other car has the number C5T K89. All DF plates for private cars and trucks have the format 123 ABC, as seen on the car driven by Creasy (845 PHY).
Continuity mistake: Near the start of the movie, when Lupita's father is talking in the restaurant, the flowers in front of him start off facing to the left, toward the other man at the table. However, after Mr. Ramos says that he is letting his bodyguard go, the flowers are facing to the right, toward him.
Other mistake: When Creasy thumbs through Pita's journal (which, unusual for American English, is addressed by her as "Dear Diary"), you can catch a glimpse on her first entry, made on a page titled "January 1", but reading "Today at school I had a great time." So, if she's alleged to be keeping her diary true-to-date, she's describing a school day on New Year's Day. Also, her handwriting changes considerably within the next three months (cf. April entry) - but then suddenly changes back in June.
Character mistake: The mother is supposed to be American, but she speaks in her native Australian accent near the end when she says, "I don't think I can take anymore of this" upon finding out that Pita may be alive.
Continuity mistake: During the first kidnap attempt, after Creasy is shot, he hides behind a green car. A shot then shows him on the ground again. (00:51:20)
