Other mistake: When the blonde arrives from Stockholm, the announcer refers to the arrival (in French) at gate "seize" which is sixteen in English. The subtitles say Gate 18, which is Dix-Huit in French. (00:36:45)
Other mistake: When Bryan is replaying the conversation between him and Kim, as she was being kidnapped, you can hear parts of the conversation that happened before he started recording.
Other mistake: Bryan is recording as his daughter is being taken. When Marko comes on the phone, Bryan unplugs the phone from the recorder to speak with Marko. So, he actually didn't record him saying "Good Luck" yet. On the plane, Marko says it on the recorder.
Other mistake: When Amanda is taking a photo, the camera phone was held in the landscape position, but when Peter is 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. Also, when Bryan was reviewing the photos, they were on a SIM card from Kim's broken phone, not Amanda's phone, which is what Peter used to take the picture.
Other mistake: In the scene at the construction site, the guy in front of Liam Neeson gets a card with the number 4. When we see him inside, he walks past the number 4 room.
Suggested correction: The guy who gets a card number 4 is not in front of Liam, he was in front of the guy who was in front of Liam, so we never saw which room he actually went into.
