Goofs

When Kim makes a phone call just before getting kidnapped, she describes the man as having a beard. When Bryan hears this recording on the plane, it's changed to mustache, and again in a later scene when Bryan is listening to the recording it's beard.

When Bryan drives Kim to the airport, exterior shots show a Nissan Sentra. Interior shots show a BMW 7-Series, as evidenced by its unique seat and headrest design.

When Bryan listens to the recording of his daughter on the airplane, the recording starts when his daughter says "They've got her", which would have been when his daughter was in the bathroom. Bryan originally started the recording after his daughter was under the bed in the bedroom, so the recording wouldn't include that part. It also would've recorded Bryan's voice, which was not on the recording.

When Bryan interrogates Marko, he removes his tie and loosens his collar. When he returns to the light switch, his tie has returned. Next time he hits the switch, the tie is missing.

After Bryan Mills saves the girl from the construction area brothel, he drives away in a white SUV. The pursuing bad guys shoot out the back window. The same window is intact in several following scenes.

Bryan's diversion with the small walkie to avoid being caught when the French agents detect his cell phone location cannot work in the way depicted. First off, walkies usually are PTT, so either you can listen or you can talk, but to change from one mode to the other, you need to push a button. Even if these walkies were to transmit and receive at the same time without hitting a PTT button though, Bryan would have to either dial or pick up the phone before he could start moving to his alternate location. That alternate on the other roof was too far for him to have reached it in the few seconds that pass between the start of the conversation and the first shot of static Bryan with his binoculars. But even if they had shown him on the move rather than observing, the French agents would have known he needed to stay in range of the low-power walkie for the trick to work, so he could not be more than a few dozen yards away.

When Bryan's friends come over for a barbecue, they are drinking Newcastle Brown Ale. However, as seen particularly with Sam's beer, the contents are too clear to be that particular brand of beer.

The police license plates have a single letter, which would make it a commercial plate rather than a police car plate. Police car plates in California only contain numbers.

When Bryan is chasing the sheikh's barge along the Seine in his car, he appears to be traveling at high rate of speed alongside the barge. The barge would likely be traveling around 5 knots, about the speed of a light jog. The speed limit for boats on the Seine is 15 knots, (about 17 mph), so even if the boat could somehow travel at the maximum speed for the river (which would be impossible for a boat like that), it would still be at a crawl for a car.

He wasn't driving alongside the barge, like a race. The barge was well ahead of him. He was speeding through traffic to catch up and get ahead far enough to jump off a bridge.

When Amanda was taking a photo, the camera phone was held in the landscape position, but when Peter was taking the photo for them, he held it in the portrait position. Later, when Bryan was reviewing the photos, all the photos were in the landscape position, including the one supposedly taken by Peter.

Some phone cameras and some print kiosks don't have the capability to switch from landscape to portrait.

Kim's map of Europe shows Czechoslovakia as one country. It split into the Czech Republic and Slovakia in 1993. However, she may have used an older map to plan her trip.

When Bryan listens to the mobile phone and the call ends, the audio sounds like a home phone cutting off, not a mobile. It's actually the sound of the phone being smashed. Later, the phone is discovered smashed.

Bryan never reloads his gun. He often takes the guns of people he has just killed, so reloading is not necessary.

When Peter jumps off the elevated road to escape Bryan, the semi-truck trailer Peter lands on clearly has a padded roof.

At LAX, Bryan discovers the map and drops his daughter off on the arrival level, even though her flight is departing for Paris. You can see they are on the lower level, which is the arrival level at LAX.

When Bryan has finished using the white SUV after the building site chase scene you can clearly see various bullet holes. These are in fact "Hardly Dangerous" bullet hole stickers that are often used in movies. This is clearly evident in the rear of the vehicle.

When the girls are in the apartment in France, they turn the music up loud so they do not hear Kim's mobile phone ring. When the camera pans over to her handbag, the phone is ringing, but "Silent" mode is selected.

When Bryan goes to the girls' Paris apartment for the first time, he edges along a ledge on the outside of the building. An overhead shot reveals an obvious stunt double.

Jean-Claude's computer has a QWERTY keyboard, a type not used in France. It should be an AZERTY layout.

When the women are taken to the sheikh, there are 3 women present including Brian's daughter, but when Brian enters, only his daughter is present. Did Brian rescue only his daughter and leave the others to slavery? The story also never accounts for the other enslaved women Brian encountered, neither the one with his daughter's jacket nor whether Amanda's body was recovered or returned to her family. They seem to be just abandoned.

When Mr Mills visits the house on Rue Paradis, he appears to use a forged French ID to introduce himself as a policeman. But he speaks perfect northern Irish English throughout the scene. No one would have mistaken him for a Frenchman.
